Kurz Flow Meter Allows Precise, Real-Time Dry Flow Measurements for Landfill Pollution Reporting

Kurz Flow Meter

Landfill gas (LFG) is a natural byproduct of organic material decomposition in landfills. LFG is approximately half methane (natural gas's primary component), half carbon dioxide (CO2), and a small amount of non-methane organic compounds. Methane is a potent greenhouse gas that traps heat in the atmosphere 28 to 36 times more effectively than CO2 over a 100-year cycle.

Landfills for municipal solid waste (MSW) are the third-largest source of human-related methane pollution in the United States, accounting for around 15.1 percent of total emissions in 2018.

LFG can be captured, transformed, and used as a renewable energy resource instead of escaping into the air. Using LFG reduces odors and other risks associated with LFG emissions and methane migration into the atmosphere, which contributes to local smog and global climate change. 

A collection of wells and a blower/flare (or vacuum) device remove LFG from landfills. The collected gas moves to a central location where it can be stored and handled, depending on the gas's ultimate use. The gas can be flared or put to good use in an LFG energy project from here.

Because of regulatory requirements, numerous landfills install gas control controls. The federal government has adopted legislation that regulates the use and upkeep of landfills. These rules help eliminate ozone precursors (volatile organic compounds and nitrogen oxides), methane, NMOCs, and odorous compounds in landfill gas pollution, which harms human health and the environment.

Thermal flow meter technology is known for having a low-pressure drop and is suitable for calculating extremely low flows. On the other hand, standard thermal flow meters do not operate well in condensing gas environments like landfill methane recovery systems. The accuracy issues associated with wet gas flow measurements grow by the unpredictability of moisture levels caused by leachate, rain, temperature, and humidity. 

The Kurz WGF flow meter is perfect for use in wet gas applications. Kurz allows you to quantify gas flow precisely and provide real-time dry flow measurements for pollution reporting (federal, state, local regulations, greenhouse gases, and the Landfill Methane Rule).

Reduced Bore Vortex Flowmeter Provides Better Measurement for Low Flow and Also Saves Cost

Reduced Bore Vortex Flowmeter

Azbil’s AX24 Multivariable Vortex Flowmeter offers accurate and reliable flow metering in a multivariable design. The multivariable design incorporates a high-accuracy velocity sensor, a precision platinum RTD temperature sensor, and a solid-state pressure transducer. The meter’s process connections match the line size but use integrated reducing flanges, and the meter body reduces in diameter, increasing the fluid velocity through the meter. Increasing the velocity in this fashion extends the meter’s measuring range to capture lower flow rates that a full line size meter might miss.

Industrial Refractometers

Industrial Refractometers

Refractometry, a mixture of physics, material science, and chemistry, is a method that calculates the composition of known substances by measuring their respective refractive index (RI). The refractometer determines dissolved solids' concentration by making an optical measurement of a solution's refractive index (nD). The refractometer measures the refractive index nD and the temperature of the process medium. The calculation is based on the refraction of light in the process medium, called the critical angle of refraction, using a yellow LED light source with the same wavelength (580 nm) as the sodium D line (thus nD). In most solutions, the concentration of solute in a solvent can be determined by measuring the refractive index nD. The relation between the refractive index and the concentration depends on the solvent and solute, temperature, and wavelength.


Typical examples of industrial refractometry uses are:


  • The calculation of the salinity of water to assess its drinkability.
  • The analysis of dissolved solids in liquor production in pulp and paper production.
  • The assessment of sugar content ratios for food products and beverages.
  • The understanding of the hydrocarbon content of motor fuels. 


These are just a few examples. There are many more common industrial uses for industrial inline refractometers and thousands of unidentified potential applications.

Level Measurement Solutions for Water Treatment

Level Measurement Solutions for Water Treatment

Several functional level measurement technologies have viable solutions for a broad range of industrial and municipal water treatment applications. Because of the variety of applications that exist and the varying application conditions, no one technology is best suited in all cases. 

POINT LEVEL VERSUS CONTINUOUS LEVEL INSTRUMENTS

Regardless of the application, there are two significant classifications of level measurement instrumentation: point level and continuous level measurement.

Point Level (On/Off) measurement indicates the absence or presence of level at a certain threshold (point) within a vessel.  Point-level switches perform as high level and spill prevention alarms, low level, pump protection alarms and pump control.

Continuous Level (Proportional) measurement indicates the level in a vessel over the full span of capacity.  These devices perform as process control as well as inventory control and management.

LEVEL CONTROL TECHNOLOGY CHOICES

The technologies used to measure level are affected differently by the varying process conditions. Below is a brief description of the different technologies commonly used in a water treatment facility.

RF ADMITTANCE/CAPACITANCE
RF Admittance/Capacitance employs a radio frequency signal and monitors for a change in capacitance. Either the presence or absence of material or how much material is in contact with the sensor, making it highly versatile and a right choice for a wide range of conditions and materials for point or continuous level measurement.

RADAR
Radar utilizes either Pulsed Wave or Frequency Modulated Continuous Wave (FMCW) through-air transmission that allows for an accurate non-contact reading of reflected electromagnetic signals.

MAGNETOSTRICTIVE
Magnetostrictive uses an electric pulse from ferromagnetic wire to accurately detect a float's position with embedded magnets.  As the pulse intersects the float's magnetic field, a second pulse reflects an electric circuit that accurately determines the distance and thus the level position.

CONDUCTIVITY SWITCHES
Conductivity switches measure the drop-in resistance when a conductive liquid contacts with two probes or a probe and a vessel wall.

ULTRASONIC (POINT LEVEL)
Ultrasonic (Point Level) measurement electronically resonates a crystal at a fixed frequency to generate sound waves that travel across an air gap to a second crystal.  As liquid fills the gap between the two crystals, the second crystal begins to resonate with the first.

ULTRASONIC (CONTINUOUS LEVEL)
Ultrasonic (Continuous Level) measurement uses a transmitter to generate an ultrasonic pulse and measures the time it takes for a reflected signal to return to the transducer to determine a liquid level.

GUIDED WAVE RADAR (GWR)
Guided Wave Radar (GWR) utilizes a Time Domain Reflectometry (TDR) technique by sending a highly focused electronic signal down a metallic rod or flexible cable waveguide. When the transmitted signal intersects the liquid's surface, it reflects along the rod or cable to determine the distance traveled. The level position is then easily inferred.

HYDROSTATIC
Hydrostatic measurement immerses a pressure transmitter with a sensing diaphragm and a sealed electronic circuitry that transmits an analog signal proportional to the liquid level above the sensor.

FLOAT SWITCHES
Float switches rely on a low-density float mounted in a vessel that magnetically couples to a limit switch. A change in fluid height actuates a switch by moving the float.

VIBRATION/TUNING FORK
The Vibration/Tuning fork is piezoelectrically energized and vibrates at a frequency of approximately 1200Hz, and as the process media cover the fork, the frequency shifts. The internal oscillator the frequency shift by and converts it into a switching command.

POINT LEVEL SOLUTIONS

Advanced RF Admittance/Capacitance point level devices are the most versatile of the point level technologies, especially with process media that can coat the sensor. They provide excellent spill/overfill protection. They are simple to install and have no moving parts, making them virtually maintenance-free. Their robust design and circuitry make them an ideal solution for many water treatment applications.

Both tuning forks and ultrasonic gap switches provide reliable high- or low-level measurements in various applications. For non-coating conductive liquids, conductivity switches provide economic priced measurement while float switches appear in many basic applications at very cost-effective prices.

CONTINUOUS LEVEL SOLUTIONS

Mechanical systems such as floats and bubblers require extensive maintenance and are less reliable and accurate than electronic systems. Hydrostatic systems afford better reliability and are simple to use, and can transmit data to another receiver for remote monitoring, recording, and control.

RF Admittance/Capacitance level is a time-proven and one of the best available technologies for indication and control. RF technology inherently provides the highest accuracy and repeatability in interface measurements. Variations in the makeup of upper and lower phases of a liquid have no appreciable effect on system accuracy. Recalibration is not required.

For short-span measurements, RF Admittance technology provides one of the most preferred readings. As the level of measurement span decreases, the more appropriate RF technology becomes. In spans of only a few inches, RF systems can repeatedly produce accuracies of 1/32ths of an inch. RF has the added benefit of not being limited by “dead zones” inherent with many popular technologies often selected for measurement ranges larger than 5 feet.

Non-metallic tanks pose no technical problems for Ultrasonic, Magnetostrictive, Hydrostatic Pressure, Radar, and GWR (Guided Wave Radar) technologies. The GWR approach is suitable for vessels with internal obstructions and uses lower energy levels than airborne radar technologies. Non-contact technologies, such as Radar and Ultrasonic, can have measurement ranges up to 130 feet. 

For long-range measurements or headroom limitations, flexible sensors offer insertion lengths up to several hundred feet for Hydrostatic Pressure and RF Admittance technology products. Loop-powered GWR (TDR)-based products allow measurement ranges up to 115 feet in selected applications. Magnetostrictive technology provides an accuracy of 0.1% of measurement span in flexible sensor designs up to a maximum range of 70 feet.
