1. The turbine is made of selected alloy material, which has very good flow stabilization and corrosion resistance. 2. Imported special bearings with long service life 3. The measurement room is isolated from the ventilation room to ensure the safety of the instrument. 4. It can detect the temperature, pressure and flow rate of the gas being measured, automatically track and compensate the flow rate, and display the gas volume accumulation in the standard state; 5. Temperature and pressure values can be queried in real time with a wide flow range, good repeatability, high accuracy, small pressure loss, and low starting flow. 6. Multi-point nonlinear correction of intelligent instrument coefficients 7. Built-in pressure and temperature sensors, high safety performance, compact structure and beautiful appearance 8. The system works with low power consumption. One 3.2V10AH lithium battery can be used continuously for more than 3 years. 9. The instrument coefficient and accumulated flow…
