Split-type thermal mass flow meter for air oxygen methane argon Nitrogen

The MEMS sensor consists of two patch platinum resistors, one measuring the temperature of the gas in the pipe and the other heated by an electric current, keeping the temperature difference between the two thermal resistors constant. As the gas flows through the thermal resistance, there is a cooling effect. As the flow rate increases, the cooling effect increases and the sensor power required to keep the temperature difference between the two thermal resistors constant increases.The power added to the heating resistance is proportional to the mass flow rate

1.Using MEMS flow sensor chips, the sensor has the characteristics of high precision, high sensitivity, and strong anti-interference capability.

2.This product comes with a display screen and control buttons, making it easy to operate and read. (Optional)

3.The zero-point stability of the sensor has been greatly improved compared to ordinary thermal flow meters.

4.High stability across the full range.

5.Full-scale high precision and excellent repeatability.

6.Combined with structural optimization, the flow meter significantly reduces pressure loss compared to traditional mechanical instruments, lowering energy consumption.

7.Uses an LCD to display instantaneous flow and cumulative flow, which is clear and intuitive, making reading convenient.

8.Optional 4~20mA standard current signal output and alarm output are available.
