Page 1 of 6 Description The measuring system is designed for flow measurement. Gas flow through the sensing section passes two PT 100 RTD transducers; one is used as a temperature sensing device whilst the other is used as a heater. The temperature sensor monitors the actual process value whilst the heater is maintained at a constant differential temperature above this by varying the power consumed by the sensor. The greater the mass flow, the greater the cooling effect and power required to maintain the differential temperature. The measured heater power is therefore a measure of the gas flow rate and is evaluated as a measuring signal using the transmitter electronics. The measuring systems consists of a transmitter and a sensor which can be mounted together (compact version) or separate (remote version). The electronic of the transmitter (type T-mass 6*) mounted inside the enclosure Proline G02.
