Micro gas mass flowmeter is specially designed for the measurement and process control of various small flow gases. This series of sensors are made of advanced micro-electromechanical system (MEMS) flow sensor chips and are suitable for all kinds of clean gases. The unique packaging technology makes it applicable to various pipe diameters, low cost, easy to install, no need for temperature and pressure compensation, and can replace traditional volumetric or differential pressure flowmeters.
1. Using micro-electromechanical system (MEMS) flow sensor chip, the sensor has the characteristics of high precision, high sensitivity
and strong anti-interference.
2. This product has a display screen and setting buttons for simple operation and direct reading. (Optional)
3. The zero stability of the sensor has been greatly improved compared with the general thermal flow meter.
4. High stability over the entire range.
5. High precision and excellent repeatability over the entire range.
6. Combined with structural optimization, the flow meter has a greatly reduced pressure loss compared to traditional mechanical instruments, reducing energy consumption
7. LCD is used to display instantaneous flow and cumulative flow, which is clear and intuitive, and easy to read.
8. Optional 4~20mA standard current signal output and second impulse output are available.
