The Level Measurement Company That Industrial Engineers Trust When It Really Matters

There's a question that practically every industrial process has to answer, dozens of times a day, across thousands of facilities around the world: how much material is in that vessel, and where exactly is the level? It sounds simple enough, but in reality, level measurement is one of the most technically demanding challenges in industrial instrumentation. Fluids foam. Solids bridge and coat. Temperatures spike and pressures fluctuate. Hazardous materials demand failsafe reliability. For engineers who live with these challenges every day, one name has stood out for decades as the company that genuinely gets it right — AMETEK Drexelbrook.

Founded in 1963 and headquartered in Horsham, Pennsylvania, Drexelbrook built its reputation on a single, transformative idea: that there was a better way to measure level than the technologies available at the time. The company pioneered RF admittance level instrumentation, coining the very term "RF admittance" to describe an approach that went beyond simple capacitance measurement. By developing its proprietary Cote-Shield technology, Drexelbrook solved one of the industry's most persistent headaches — the problem of conductive material coating the sensor and causing false readings. That breakthrough alone set the company apart, and it's been setting the standard ever since.

Today, AMETEK Drexelbrook operates as part of AMETEK Level Measurement Solutions, a division of AMETEK, Inc., a global industrial technology leader with approximately $7.5 billion in annual sales. Being part of AMETEK gives Drexelbrook the engineering resources and global reach of a major corporation while maintaining the deep application expertise and product focus that made it great in the first place.

What Does Drexelbrook Actually Make?

Drexelbrook's product portfolio is genuinely comprehensive, which matters because no single measurement technology works well in every situation. The company offers point level switches and continuous level transmitters across multiple technology platforms — RF admittance, ultrasonic, open-air radar, magnetostrictive, and guided wave radar. That breadth means a Drexelbrook engineer can honestly recommend the best technology for your specific application rather than shoehorning your problem into the one solution they happen to sell.

The RF admittance product line remains the crown jewel and is widely considered the industry's gold standard for difficult applications involving viscous fluids, slurries, foamy materials, and coating-prone substances. For non-contact applications, the USonic ultrasonic transmitters feature patented SmartGain technology that automatically ignores false echoes from tank obstructions and agitator blades — no manual tweaking required. The open-air radar transmitters use FMCW technology for highly accurate continuous measurement even in vapor-heavy or turbulent environments.

One product that deserves special mention is the Universal Water Cut Meter, which measures the water content of crude oil flowing through a pipeline. It's a niche application, but a critically important one for the oil and gas industry, where accurate water cut measurement directly impacts production accounting and revenue calculations. Drexelbrook's decades of capacitive measurement expertise make it one of the few companies capable of doing this reliably.

More recently, Drexelbrook has moved into Industrial IoT with the BrightTEK wireless tank monitoring system, which includes satellite uplink capability for remote or off-grid locations. That's a meaningful evolution for a company with roots in analog instrumentation.

Who Trusts Drexelbrook?

The customer list reads like a map of heavy industry. Oil refineries, petrochemical plants, pharmaceutical manufacturers, food and beverage processors, pulp and paper mills, water and wastewater treatment facilities, power generation plants, mining operations, cement manufacturers, steel mills — if there's a vessel with a level that needs measuring, Drexelbrook has probably solved that problem for someone in that industry already.

In safety-critical applications, Drexelbrook's commitment to reliability really shines. Many of their instruments carry SIL 2 certification, with SIL 3 capability in redundant configurations, as well as FM, ATEX, and IECEx approvals for hazardous-area use. Features like AutoVerify and Manual Certify allow operators to confirm that their level switches will actually respond when called upon — without interrupting the process or pulling the sensor. For high-level alarms on storage tanks or overfill protection systems, that kind of confidence isn't a luxury; it's a legal and ethical requirement.

A Reputation Built on the Hard Stuff

What's most telling about AMETEK Drexelbrook's reputation isn't what they say about themselves — it's the applications engineers trust them with. When process conditions are harsh, when the material is problematic, when the consequences of a bad reading are serious, that's when experienced instrumentation professionals reach for Drexelbrook. More than 60 years of application data, a genuine commitment to recommending the right technology for each job, and products built to perform in conditions that would defeat lesser instruments — that combination is why Drexelbrook remains the reference standard in industrial level measurement.

Precision in Motion: How Smart Positioners Drive Modern Plant Performance

Industrial processes rely on tight, repeatable valve control, and electro‑pneumatic smart positioners now sit at the heart of that mission. A smart positioner receives a 4‑20 mA or digital command from the control system, compares that signal with live stem or shaft feedback, and modulates air to the actuator until the valve reaches the requested position. Integrated microprocessors execute this closed‑loop routine in a few milliseconds, which lets the positioner correct friction, supply‑pressure swings, and process disturbances before those issues disturb the loop. Because the device continually confirms where the valve sits rather than where it should, operators gain true position certainty and tighter process variability.

The electronics that drive this precision also unlock diagnostics. Embedded memory tracks travel counts, cycle time, pressure differential, and deviation statistics so maintenance teams can spot packing wear or air leaks early instead of reacting to a stuck valve later. Configuration tools built on HART, Foundation Fieldbus, or similar protocols let technicians commission, tune, or interrogate the instrument from the safety of the control room rather than climbing scaffolding with a handheld calibrator. That combination of self‑diagnosis and remote access sharply lowers mean time to repair while trimming the person-hours once devoted to periodic stroke checks.

Chemical plants illustrate the value. They meter acids, bases, and solvents that challenge elastomers and trims; when temperature spikes or polymer fouling changes valve friction, the smart positioner compensates instantly, so the recipe stays on spec. Pulp and paper mills use large rotary control valves to throttle steam, white liquor, and bleaching chemicals. Heavy stock concentration and high differential pressures can create stiction. Still, a modern positioner’s high‑gain air relay and adaptive PID tuning keep the digesters stable and the sheet basis weight flat. Food and beverage processors lean on sanitary diaphragm and butterfly valves. Smart positioners speed Clean‑in‑Place cycles because their fast response clears lines quickly, and their stainless or polymer housings tolerate caustic wash‑downs. Water and wastewater utilities use them on filter backwash and disinfection skids, where the instruments’ low air consumption shrinks compressor power while continuous valve signature tests satisfy regulatory documentation.

Westlock Controls designed its K20 Smart Positioner to deliver those benefits easily. The front‑mounted LCD presents plain‑language menus, and a technician can complete auto‑calibration in less than one minute, even on large rotary actuators. The device includes optional HART 7, which means engineers can pull trend data or trigger calibration from any compliant asset‑management suite without cracking the enclosure. A non‑contact Hall‑effect sensor replaces gears and potentiometers, so wear never drifts to zero, and vibration never loosens a linkage. Standard 4‑20 mA position feedback comes built‑in, eliminating an external transmitter and the extra tubing and terminations that often leak or corrode. Users can order embedded limit switches to satisfy permissive logic or proof‑test routines without bolt‑on boxes. At the same time, NAMUR mounting speeds installation on quarter‑turn actuators found throughout water plants and CIP skids. Intrinsically safe and non‑incendive approvals extend the same features into solvent recovery units and Class I areas in chemical and pulp facilities. Rugged resin, low‑copper aluminum, and 316 SS housings let specifiers match the environment, whether the positioner faces salt spray at a coastal desalination plant or caustic liquor in a bleach tower. 

In short, electro‑pneumatic smart positioners translate digital intent into precise mechanical motion while furnishing the insight and resilience that today’s plants demand. Westlock’s K20 embodies that role: it couples rapid, foolproof commissioning with diagnostics and feedback that sharpen control and slash downtime, all wrapped in a sensor architecture that refuses to drift. Plants that deploy it gain tighter loops, faster startups, and lower lifecycle costs—benefits that resonate from batch reactors to aeration basins and every valve stroke in between.

The Versatility and Precision of Variable Area Flowmeters (Rotameters)

A rotameter, a variable area flowmeter, is essential for fluid measurement. It provides a simple yet effective means of measuring the flow rate of liquids or gases in a closed system. The rotameter operates on a straightforward principle: a fluid flows through a vertical, tapered tube, lifting a float inside. As the fluid moves, it pushes the float upward, and its position in the tube corresponds to the flow rate. The wider the area the fluid flows through, the higher the float rises. This design allows for an immediate visual flow readout, with markings on the tube indicating precise flow rates.

The rotameter's working mechanism relies on the balance between the upward force of the fluid flow and the downward force of gravity on the float. As the flow increases, the float moves higher up the tube until these forces are in equilibrium. Conversely, if the flow decreases, the float drops. A key feature of rotameters is that the flow reading is direct and doesn't require additional instrumentation, making it highly user-friendly. The taper of the tube and the float design vary depending on the fluid's properties, such as its viscosity and density, ensuring accurate measurements across a range of conditions.

Rotameters are versatile and used in many industries where accurate flow measurement is crucial. In the chemical processing sector, for example, rotameters measure the flow of various chemicals in production lines, ensuring the correct dosages and proportions. Pharmaceutical companies also rely heavily on rotameters for accurate measurement of liquid ingredients in the production of drugs, where precision is critical for quality control and regulatory compliance. Similarly, in the oil and gas industry, rotameters monitor the flow of gases such as nitrogen or oxygen, essential in upstream and downstream operations. The ability to handle corrosive materials and aggressive chemicals makes rotameters especially valuable in harsh industrial environments.

The water treatment industry is another area where rotameters play a pivotal role. Here, they monitor the flow of water and chemical additives to ensure proper filtration, purification, and disinfection processes. By keeping an eye on flow rates, operators can maintain optimal system performance and prevent the waste of resources. In HVAC systems, rotameters regulate the flow of gases and liquids, ensuring energy efficiency and the proper functioning of heating, ventilation, and air conditioning units. These industries rely on rotameters because of their simplicity, reliability, and ease of use, making them a go-to solution for many fluid management needs.

Rotameters are not just for industrial use, but they also find a place in laboratory and research environments where precise control over gas and liquid flow rates is required.

Pressure Drop Characteristics Across Different Industrial Valve Types

Pressure drop significantly affects the design and operation of industrial valve systems. It refers to the reduction in pressure as fluid flows through a valve. Several factors influence this phenomenon, including valve type, flow rate, fluid properties, and valve geometry. Understanding pressure drop ensures efficient and safe operation of fluid systems. Here’s a detailed description of the pressure drop as it applies to various types of industrial valves:

Ball Valves

Ball valves offer simplicity, durability, and tight seals in industrial applications. The valve uses a spherical ball with a hole through the middle, aligning with the pipeline to allow or block flow.

Pressure Drop Characteristics:

• Low Pressure Drop: Fully open ball valves exhibit a low pressure drop due to their straight and unobstructed flow path. The smooth, rounded interior of the ball minimizes turbulence and resistance.
• Impact of Partial Opening: Partially open ball valves significantly increase pressure drop. The fluid navigates around the partially obstructed path, creating turbulence and resistance.
• Valve Size and Flow Rate: Larger ball valves and higher flow rates reduce the relative pressure drop, but designers must consider potential cavitation and erosion.

Gate Valves

Gate valves primarily control on/off flow in a pipeline. They consist of a gate (or wedge) that moves up and down to start or stop the flow.

Pressure Drop Characteristics:

• Minimal Pressure Drop when Fully Open: Fully open gate valves exhibit very low pressure drops because the gate remains entirely out of the flow path, allowing fluid to pass with minimal resistance.
• High Pressure Drop during Partial Operation: Partially open gate valves significantly increase turbulence and pressure drop, making them unsuitable for throttling applications.
• Design and Maintenance: When open, a straight-through flow path minimizes pressure drop, but over time, wear and tear on the gate and seat can impact performance and increase pressure drop.

Globe Valves

Globe valves excel at regulating flow and are used in applications requiring precise flow control. They consist of a movable disk-type element and a stationary ring seat in a spherical body.

Pressure Drop Characteristics:

• Higher Pressure Drop: Globe valves inherently exhibit higher pressure drops than ball and gate valves due to the fluid changing direction as it passes through the valve. The tortuous path creates more resistance.
• Flow Control: Globe valve design makes them ideal for throttling and precise flow control, but this advantage comes with higher pressure drops.
• Valve Position: The valve opening degree significantly affects the pressure drop. Partial opening creates more resistance and higher pressure drops due to increased turbulence.

Butterfly Valves

Butterfly valves control flow using a rotating disc. They are commonly used in applications requiring quick shut-off and suit large-diameter pipes.

Pressure Drop Characteristics:

• Moderate Pressure Drop: Fully open butterfly valves exhibit moderate pressure drops because the disc remains in the flow path even when rotated to the open position, creating some obstruction and turbulence.
• Variable Pressure Drop: The pressure drop increases as the valve moves towards the closed position. The partially obstructed disc increases flow resistance and turbulence.
• Efficiency and Application: Butterfly valves efficiently handle large volumes of flow with moderate pressure drops. They are often used in water distribution, HVAC systems, and various industrial applications where space and weight considerations matter.

Factors Influencing Pressure Drop Across Valves

Several factors influence pressure drop across industrial valves:

1. Valve Design: Internal valve geometry, including the flow path and obstructions, plays a significant role.
2. Flow Rate: Higher flow rates generally increase pressure drop due to greater frictional forces.
3. Fluid Properties: Fluid viscosity and density affect how they interact with valve surfaces.
4. Valve Size: Larger valves typically exhibit lower pressure drops for a given flow rate than smaller valves.
5. Operational Conditions: Valve position (fully open, partially open, or closed) significantly affects pressure drop.

Understanding these characteristics helps select the appropriate valve for specific applications, ensuring efficient and safe operation while maintaining desired flow control and minimizing energy losses.

Industrial Open Air Radar Transmitters Powered by FMCW Technology

Basic Understanding of Radar

Radar (Radio Detection and Ranging) is a system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. It transmits a signal, bouncing off the target and returning to the radar system. By analyzing the reflected signal, the radar can determine various parameters about the target.

FMCW (Frequency Modulated Continuous Wave)

When discussing FMCW, we are talking about a specific type of radar signal. Here's how FMCW works:

1. Continuous Wave (CW): Traditional radar systems emit a brief pulse of radio energy and then wait for that pulse to reflect off an object and return. In contrast, Continuous Wave radar emits a constant signal or wave.
2. Frequency Modulation (FM): In FMCW radar, the frequency of the continuous wave signal is varied or modulated over time. This can be done linearly, where the frequency increases or decreases at a constant rate or in other patterns.

The benefit of FMCW is that the frequency change provides a way to determine the range (distance to an object). There's a delay when the transmitted wave bounces off an object and returns. During this time, the transmitted wave's frequency has changed. By comparing the received wave's frequency to the current transmitted frequency, the radar system can determine how long it took for the wave to return and thus calculate the distance to the object.

FMCW radar is handy because it can be more compact, requires less peak transmit power (because it's continuous wave and not pulsed), and can provide range and speed information simultaneously.

Open Air Radar Transmitters

"Open air" in the context of radar transmitters usually refers to systems that operate without waveguides or enclosed transmission mediums. Instead, they transmit their signals directly into the environment. These systems are used in various applications, including vehicle radars (like those used in adaptive cruise control or autonomous vehicles), weather radars, and more.

Summary:

An open-air radar transmitter that uses FMCW is a radar system that transmits a continuous wave signal directly into the environment, modulating the signal's frequency over time. By analyzing the frequency shift of the returned signal relative to the transmitted signal, the radar can determine the range to the reflecting object. This technology is widely utilized due to its efficiency, compactness, and ability to provide detailed information about detected objects.

Drexelbrook's open-air radar products deliver exceptional resolution and accuracy tailored for demanding applications. These instruments harness FMCW (Frequency Modulated Continuous Wave) technology, ensuring a powerful signal at the measurement surface. This robustness guarantees optimal return signals, even when measuring agitated liquids.

A Drexelbrook radar level transmitter stands out as the optimal choice for applications that necessitate non-contact technology.

Advanced Water Level Monitoring in Sewage Pools

The complex sewage system of a power plant necessitates immediate maintenance and management. The water utilized for operating turbines and other waste materials runs through the sewage system, and ultimately to the municipal wastewater treatment facility.

Some treatment pools are located in isolated areas around the plant, making it challenging for maintenance staff to access and repair damage promptly. Plant maintenance personnel continually look for ways to more effectively manage the pools and avoid situations where wastewater could overflow.

With the sewage system linked to a central control room, data from each sewage pool has to be transmitted to the primary Distributed Control System (DCS). To achieve optimal management of the sewers, continuous monitoring and attendants are usually necessary.

Technicians understand that sewer blockages inevitably lead to wastewater flooding due to the time required for the equipment to address the backup. This flooding results in significant damage to the surrounding area. Hence, it is crucial to regulate the wastewater level in the pools to prevent such incidents from occurring.

An outstanding solution for this problem is to install two Drexelbrook USonic continuous level transmitters to monitor level in the sewage pools. The USonic's capability to deliver contactless, continuous, and precise water level readings in the pools provide engineers with a comprehensive understanding of the pools' condition. The device's compact size and integral design facilitate easy installation, enabling a quick and efficient solution. With a measuring range of up to 30 feet, the USonic effortlessly provides water level readings of the 12-foot-high sewage pools. Its scan distance function can identify obstacles in the pool and record interfering signals. The USonic connects to the central control system via a 4-20mA interface, granting the engineers constant oversight of the water levels in the sewers, ensuring that the sewers would maintain the appropriate water level and the system would receive a notification in the event of an emergency.
