Compressed Air Flow Meter

Process Control Devices offers Compressed Air Flow Meter. The thermal principle operates by observing the cooling effect of a gas flow as it passes over a heated transducer. In compressed air flow meter, the temperature sensor monitors the actual air temperature whilst the heater transducer is maintained a constant differential temperature by caring the required current to the heating sensor from electronic in order to maintain the differential temperature. Greater the flow, greater will be cooling effect and current required to maintain the differential temperature. The current produce to maintain this temperature differential is directly proportional to the mass flow rate. Hence there is no need for additional temperature or pressure compensation in the thermal mass flow meter. This makes thermal mass flow meters as a preferred choice for use in compressed air flow monitoring systems.
