Specific Parameters |
Value / Description |
|
Measurement Principle |
The electronic turbine flow sensor operates based on turbine measurement. When the fluid passes through the sensor, it drives the turbine rotor. The rotation speed of the turbine is proportional to the flow rate. The built-in intelligent circuit processes the signal and provides various outputs, including switch, analog, pulse and RS485 communication, achieving accurate flow monitoring and control. |
