This video shows how to verify callibration of the Magnetrol® TA2 thermal mass flow meter at the customer site, eliminating the time and expense of sending the flow meter back to the factory to verify its callibration.
Many thermal mass flow meters are of the insertion type. As a starting point, proper insertion depth and straight run per the manufacturer’s recommendations should be adhered to. There will also be a flow arrow located on the probe or flange depending on the process connection. This is because thermal mass flow meters are calibrated in one direction and are only accurate in the direction for which it was calibrated. If not installed properly it can still measure and be repeatable but accuracy will be affected.
Verifying flow meter performance is an essential step in ensuring your flow meter is meeting its specifications. Manufacturers design-in diagnostics tests that can be run in the field, in the pipe (in-situ) or in the instrumentation shop.
Advantages of Thermal Dispersion Switches for Pump Protection
Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD. As the temperature difference increases or decreases due to heat transfer, the set point is reached and the relay de-energizes. These devices can be employed to protect pumps from potentially damaging operating conditions.Thermal dispersion switches use similar principles as thermal mass flow meters.

There are many well documented flowmeter technologies that are essentially trying to accomplish the same thing– measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flowmeters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flowmeters, however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.
WWTP Grease-to-Gas Initiative
Enabled by Advanced Level and
Flow Control Technology
Turning a waste product into a useful commodity is one of
the seminal achievements of the Green Revolution. There’s no
better example of this than the modern day “bioalchemy” that
transforms waste grease into prime biogas that can fuel heating,
dehumidification and power generation units at wastewater
treatment plants (WWTPs).
Thermatel® TA2 thermal mass flow meters are up to the challenge of your most demanding applications. TA2 thermal mass flow meters will help optimize your green energy initiatives by improving measurement of greenhouse gases and making processes less energy intensive and more energy efficient.
Thermal flow meters measure flowrate in units of mass flow rather than flow at operating conditions. Because temperature and pressure variations will influence the gas density, mass flow measurement provides optimum measurement accuracy despite temperature and pressure variations. The following paper provides a summary of common applications for Magnetrol® International’s Thermatel® thermal mass flowmeters.
The first step to energy management and reducing the energy usage is to obtain good measurements of the flowrates of each individual combustion source. In addition to providing tools for improving energy management, the measurement of the natural gas utilized by individual combustion sources may also permit users to meet the regulatory requirements for determining emissions by reporting actual (rather than estimated) natural gas usage for each individual combustion source within the facility.
Energy efficiency is more crucial to the water industry than ever before. With ever-increasing costs and regulatory pressure, plant operators are constantly looking for ways to strategically manage energy use. With solid backing from the concept that knowledge is power, Magnetrol International has introduced its Thermatel product line to help treatment plants understand their energy use by gauging heat transfer.
Using Thermal Dispersion Air Flowmeters in Wastewater Treatment Plants
Compressed air is normally used to provide air into Activated Sludge wastewater aeration basins. Controlling the amount of air that is released is very important since it controls the growth and the health of the microorganisms. Thermal dispersion air flowmeters can be effectively used to control the amount of air to run such systems properly.
Thermal Dispersion Flowmeter Technology Helps Utility Meet Federal Environmental and Health Regulations
Many water quality plants are using flow controls to help achieve critical operational goals. This recent case study shows how thermal mass flowmeters can help your plant ensure compliance with stringent government regulations.
A leading Oil & Gas company required a gas flow measurement technology that could accurately measure natural gas flow rates at their compressor stations. One of the applications of interest was measuring vent gas emissions from the packing systems of compressors. This application not only requires flow measurement at very low flows and low pressures, but the capability of achieving high turndown as well.
Low-Flow Sensitivity Means High Reliability for Flare Gas Applications
The Thermatel® TA2 thermal dispersion mass flow meter provides reliable mass flow measurement for flare gas applications to comply with monitoring requirements. No additional pressure or temperature compensation is necessary to achieve a flow rate at standard or base conditions from a single transmitter.
A single TA2 model series for all applications, features and approvals required. Universal approvals include cFMus, ATEX, IEC, EAC, INMETRO, KGS and CCOE. Accepts both AC and DC input power.
Thermal mass flow technology is a method of gas flow measurement that does not require correction for changes in process temperature or pressure. Thermal mass flow technology also has a benefit of measurement at low velocities and greater turndown capabilities than those obtainable with other flow measurement devices.
