Gas turbine flowmeter Selection tips
choose Gas turbine flowmeter The following parameters need to be determined in detail: pipe diameter, measuring medium, working temperature, pressure
Force (working state or standard state), installation mode (pipeline or plug-in), power supply (12V, 24V or battery
Power supply), output mode (4-20mA, pulse output or 485 communication), large flow (working state or standard state),
Explosion proof is required, and companion flange is required for flange connection type.
