Turbine Flow Meter is a volumetric measuring turbine type of Impeller Flowmeters , made up of sensors and Convertor. The flowing fluids engage the rotor causing it to rotate at an angular velocity proportional to the fluid flow rate. The Sensor reacts to the average velocity of fluid with the multi-blades rotor so as to speculating the flow value and the accumulative flow value.
The turbine flow meter is an ideal solution when high accuracy, compact size, fast response, and high tolerance to shock and vibration are critical requirements and suitable for a wide range of viscosity medium including oil, gas, water and wastewater, chemical, gas utility, power, food and beverage, aerospace, pharmaceutical, etc.

How to select right Turbine flow meter?
The key questions which need to be answered before selecting a turbine flowmeter are:
1.what's the fluid ?
2.what's the flow range? and pipe size?
3.what's the working pressure?
4.what's the working temperature?
5.do you need display or not?
