Turbine flowmeter for liquid

Our liquid turbine flow meter features a high accuracy of 0.2%, 0.5% and 1%. The Tungsten carbonized shaft and bearing ensures the product is enduring. Meanwhile, our product could resist erosions such as sea water, ammonia, etc. With optional parts, our product could also measure bidirection flow.

Besides, with a pulse current of 4~20mA DC, our product could display the total amount of flow and its rate. The input power is 5~24V DC. Moreover, our product reaches Ex d II BT4 explode proof standard and the DN range is 2 to 300mm.
