Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where is applicable. Optional accessory modules can be used to export the signal to other equipment. This type flowmeter is mainly used for liquid which don't corrode with SS304, SS316, Al2O3, 2Cr13. And the liquid is clean no fiber, no particles. When connect with other indicating instrument, can realize definite quantity control and over flow alarm.
Turbine meters are simple to operate and maintain, and in service worldwide as a reliable, cost-effective method for achieving accurate flow measurement. Turbine flow meters are designed to maximize throughout and minimize pressure drop, maintain high flow rates over an extended flow range and offer pulse output that is linear to the flow rate. The turbine meters also minimize fiscal measurement uncertainty by delivering high-frequency pulse resolution to account for minute increments of the flow rate.
