Thermatel® TA2, Thermal Mass Flow Meter - Reliable mass measurement for air and gas flow applications

Today’s THERMATEL Model TA2 Thermal Mass Flow Transmitter provides reliable mass measurement for air and gas flow applications. The powerful, yet easy to use electronics are contained in a compact explosion proof enclosure. The TA2 is available with both insertion probes as well as flow body design for smaller pipe sizes. The TA2 offers excellent performance at an exceptional value:

• Direct mass flow measurement of air and gas;
• Strong signal at low flow rates with high turndown;
• Process temperatures to + 200°C;
• Rotatable housing & display for viewing from all angles;
• Built-in totalizers & optional second mA & pulse outputs; and
• Field calibration verification.

Thermal dispersion mass flow technology is rapidly becoming a preferred method to measure the flow rate of gas for industrial process operations.

Thermal mass flow meters offer an attractive alternative to older measurement technologies, because they provide a direct, accurate measurement of mass flow rate, without having to correct for temperature and pressure conditions.

Additionally, because of its properties of low flow sensitivity, wide turndown and low pressure drop, thermal dispersion mass flow measurement can improve process control in a wide variety of typical and more challenging applications.

About Thermal Mass Flow Measurement
Thermal flow meters are primarily used in air and gas flow measurement applications. The meters consist of a transmitter and probe with temperature sensors (RTDs) located in the pins at the bottom of the probe.  One sensor measures the process temperature and the other sensor is heated to a specific temperature above this. As the flow rate increases heat gets taken away from the heated sensor. Some manufacturers use a variable power operation to keep the temperature difference constant, while others keep the power constant and measure the temperature difference. The Magnetrol® Model TA2 measures the power it takes to maintain a constant temperature difference between the sensors. This relationship between power and mass flow rate is established during calibration.
