2. High performance intelligent microprocessors and analog-to-digital/analog-to-digital conversion chips;
3. Wide range ratio 1000:1; Large caliber, low flow rate, negligible pressure loss;
4. Directly measure mass flow without temperature and pressure compensation;
5. Low flow velocity measurement is very sensitive;
6. Convenient design and selection, easy installation and use;
7. Suitable for measuring the flow rate of various single or mixed gases.

3、 Product features of thermal gas mass flowmeter
1. Adopting highly stable platinum RTD sensor technology
2. Adopting the technology of 'balanced structure packaging' and self compensating for medium temperature
3. Algorithms that can achieve high linearity, high repeatability, and high accuracy
4. The range ratio is 1000:1 and can be expanded according to user requirements
5. It can achieve measurement of large pipe diameter and small flow rate. Small flow rates can be measured as low as zero, with a resolution of 0.001m/s
6. No movable parts, vibration effects can be ignored
7. The requirement for straight pipe sections is not higher than 1-2D
8. Unrelated to the temperature and pressure of the medium
9. High temperature algorithm, the medium temperature can reach+510 ℃,
10. Adopt high humidity algorithm to achieve high-precision measurement
11. Enter 12 point dynamic correction for traffic signals, with built-in 10 point correction
12. Online dynamic correction of current/voltage output
13. Not sensitive to small particles such as dust
14. Online uninterrupted loading and unloading, easy maintenance
