6 / 16 page  A G E N C Y A P P R O V A L S T E C H N O L O G Y THERMATEL Model TA2 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. There is an inherent non-linear relationship between power and mass flow. The microprocessor in the TA2 compares the power against the calibration curve and converts the power requirements to the mass flow rate. Temperature is also measured to provide temperature compensation of the mass flow over the operating range of the instrument. For further information on thermal mass flow measurement, request a copy of the MAGNETROL “Thermal Dispersion Mass Flow Measurement Handbook,” Bulletin 54-621.
