The AMETEK Drexelbrook Impulse Guided Wave Radar Level Transmitter

The Drexelbrook Impulse is a guided wave radar (TDR) that measures all liquids and slurries' overall level and other volumetric measures. When competitive water sensors fail, the Impulse continues to provide accurate values. 

The Drexelbrook Impulse is a two-wire guided wave radar that uses field-proven TDR level (Time Domain Reflectometry) technology to produce accurate Total Level, Distance, and Volumetric outputs on all liquids and slurries. 

The Impulse handles even the most challenging level measuring applications. It will continue to give dependable and accurate measurements even in the presence of disturbances such as agitated or uneven surfaces, foam, or probe coating. Changes in the density and dielectric characteristics, dusts, mist, and turbulence do not affect it. When other water level sensors fail, the Impulse continues to measure. 

This water level sensor is a perfect replacement for costly mechanical dispenser systems, with a wide range of probe types and material possibilities for various applications. 

This guided wave radar is simple to use for any user due to its simple navigation, push-button setups, and HART connections. It only takes a few minutes to install. Choose your level measuring type and language, and the Impulse is ready to use. 

The Impulse guided wave radar is intrinsically safe, explosion-proof, and non-incendive, and it does not require calibration or level changes.

Additionally, Drexelbrook recently introduced an enlarged coaxial sensor for The Impulse GWR. The new 1.66" (42mm) diameter probe provides reliable accuracy within high viscosity liquids. The new enlarged coaxial sensor option for The Impulse GWR allows the material to flow off the sensor easily when used with viscous fluids.

Industrial Process and Commercial Pressure Gauge Selection

Download the US Gauge Product Selection Guide from this link.

Pressure gauges are ubiquitous in practically all industries on machines all around the world. At the same time, there are millions of different combinations of shapes, sizes, options, and materials. It's imperative to follow these five application factors for safe use and extended product life.

Process Media

Because direct contact of the sensing element to the process media is possible, any caustic media, particle media, or media that can harden and clog the pressure gauge element, must be avoided. Using a direct connection and Bourdon tube sensor is satisfactory for a non-clogging, non-corrosive medium. Use a diaphragm seal for process media that could cause blockage or be corrosive.

Temperature of the Process Media

Very hot media, such as steam or hot water, can raise the internal temperature of the gauge, resulting in failure or a dangerous state. For high-temperature applications, use a gauge "siphon" or diaphragm seal.

Environment and Ambient Operating Temperature

It is critical to understand the rated ambient environment for any instrument. Elevated ambient temperatures, dampness, vibration, and corrosive environments can all impact accuracy, calibration, and safety. If oxidizing or reducing atmospheres exist, select the appropriate case and mechanism materials, and consider installing supplementary devices, such as remote diaphragm seals, to move the gauge.

The Potential for Severe Pressure Fluctuations

The addition of pressure restrictors, snubbers, or liquid-filling will increase the service life of the pressure gauge in applications where dramatic line pulsations or high over-pressure conditions are possible.

Installation Orientation and Connection Type

Bottom (radial) and rear connectors are standard on pressure gauges. NPT (National Pipe Thread Taper) threaded connections are the most common. However, numerous different process connections are available, including straight threads, metric threads, and specialized fittings. Make sure you understand how the gauge is connected. Pressure gauges should almost always be upright when installed.
