Tips: Soap film flow meter for gas volume introduction
ATO-HM series soap film flowmeter is used to determine the volume flow of gas, belongs to the first-class flowmeter, the accuracy is better than ±1%. This series of volume flow meter consists of microcontroller, infrared sensor, pre-circuit, driving circuit, keypad, display, power supply and other parts, through its internal circuit control unit and sensitive components to measure gas flow, with fault self-testing and automatic adjustment function, no need for personnel adjustment.
Built-in conversion function, can carry out the conversion of work sinking flow rate and standard flow rate. Gas flow rate can be measured for a single time, or the average value can be taken after several measurements (the number of measurements can be set). It is often used for flow measurement and calibration of atmospheric sampler, dust sampler, gas chromatograph, rotor flowmeter, orifice flowmeter, mass flowmeter and so on.
