The gas turbine flowmeter is a new generation of high-precision and highly reliable gas precision metering instrument, which integrates temperature, pressure, flow sensors and intelligent flow totalizer, and is developed by absorbing the advanced technology of flow meters at home and abroad to optimize the design, and integrating the theories of aerodynamics, hydrodynamics, electromagnetism, etc. It has excellent low pressure and high pressure metering performance, Multiple signal output modes and low sensitivity to fluid disturbance.

Product features:

1. Turbine made of selected alloy material has very good current stabilization and corrosion resistance

2. Imported special bearing, long service life

3. The metering room is isolated from the ventilation room, ensuring the safety of the instrument

4. It can detect the temperature, pressure and flow of the measured gas, automatically track and compensate the flow, and display the cumulative volume of the gas in the standard state;

5. Real time query of temperature and pressure values Wide flow range, good repeatability, high precision, small pressure loss, low starting flow

6. Multi-point nonlinear correction of intelligent instrument coefficient

7. Built in pressure and temperature sensors with high safety performance, compact structure and beautiful appearance

8. The system works with low power consumption, and a 3.2V10AH lithium battery can be used continuously for more than 3 years

9. Instrument coefficient and cumulative flow value will not lose power for ten years
