Thermistor and a precision resistor Wheatstone bridge, the two thermistors (RTD), respectively, as the two arms, a measure of the temperature of the gas medium used - temperature components; the other is used to measure the flow rate of gas velocity Yuan. Speed ??element by the current heating to a temperature higher than a constant value electromagnetic flowmeter parameters than the temperature element, when the gas flows, the market price of the gas to remove heat from the electromagnetic flow meter speed element, so that the speed element temperature decreases, since the electrical feedback the bridge, the heating current is increased electromagnetic flowmeter, so as to maintain constant the temperature difference between the two thermistor. In this process, the heating of the electric power and the gas has a single-valued function of the quality of the relationship. Therefore, the size of the heating current measured gas mass flow rate can be obtained. When the actual gas volume flow measurement, should first flow units (eg SCFM, LPM, etc.) into the actual condition of the unit, and then determine the flow meter diameter, the following formula can be used for the actual conditions and standard volume volume unit conversion. ACFM = SCFM × 14.7 / Pa × Ta / 530ACFM: actual operating conditions of gas flow rate ft3 / minSCFM: gas flow under standard conditions ft3 / minPa: operating pressure (PSIA) = PSIG + 14.7Ta: Kim temperature (R) = F +460 manufacturer of electromagnetic flowmeters, electromagnetic flowmeters, Anhui Electric Group provided by the Anhui Electric Group Company Limited.
