Thermal Mass Flow Meter
Thermal Mass Flow Meter
Process Control Devices offers Thermal Mass Flow Meter. Thermal Mass Flow Meter is accurate, easy to install, having no moving parts and best suitable solution for measuring and controlling compressed Air, oxygen, nitrogen, biogas, digester gases, ethane and natural gas flow. Heat dispersion (mass flow) technology to provide proportional mass flow measurement resulting in higher accuracy performance at a lower cost than orifice flow meter, Vortex shedding flow meter and other gas flow measuring devices. Operating Principle: The thermal principle operates by observing the cooling effect of a gas flow as it passes over a heated transducer. The temperature sensor monitors the actual gas temperature whilst the heater transducer is maintained a constant differential temperature by caring the required current from electronic to maintain the differential temperature. Greater the flow, greater will be cooling effect and power required to maintain the differential temperature. The energy required maintaining this temperature differential is directly proportional to the mass flow rate. Thus, there is no need for additional temperature or pressure compensation in thermal mass flow meter. This meter is also used for compressed air flow measurement.
