Abstract

A kind of design method for thermal gas mass flowmeter based on platinum film resistors on ceramic substrate is presented

principle of thermal gas flowmeter is analyzed

platinum resistive flow sensor based on ceramic substrate is made. In order to reduce power supply

through-hole scheme is proposed. A prototype is fabricated with a thermostatic control circuit and MSP430 MCU processing circuit. Calibration and test are implemented using sonic nozzle calibration device

measurement range of flowmeter is 500

1 500 kg / h

precision is ± 0. 5 %

and response time is 2 s

which meet demand for most industrial pipe air mass flow test

and has broad application prospects.
