The Thermatel® Model TA2 is an easy-to-use, economical, continuous gas flow meter that is often utilized to manage energy costs or to meet environmental regulations in a variety of industries. TA2 total cost of ownership is reduced through ease of installation, calibration verification in the field and reduced maintenance with no moving parts or ports to plug. Since the measurement is based on heat transfer, the TA2 has reliable performance at low gas flows and pressures where other technologies have difficulties.
THERMATEL Model TA2 mass flow transmitter measures mass flow by detecting heat dissipation from a heated surface. The sensor contains two mass balanced elements with precision matched RTDs. The reference sensor measures the process temperature (up to +400° F [+200° C]); the second RTD measures the temperature of the heated sensor. The power to the heater is varied to maintain a constant temperature difference above the reference temperature.
