KF510-JA Series Wafer Type Paddlewheel Flowmeter - Ningbo KIO Flow Instruments Co.,Ltd.

From DN15 to DN250, easy to install and maintain

KF510-JA Series Wafer Type Paddlewheel Flowmeter is commonly used for liquid flow measurement in industries such as water supply and drainage systems, petroleum, chemicals, and hydraulic systems. Featuring a simple structure and easy installation, it is widely applied in both industrial settings and laboratories. Its measurement principle involves fluid flowing through the flowmeter, driving the paddlewheel to rotate at a speed proportional to the fluid velocity. The paddlewheel drives an electromagnetic device, converting mechanical rotation into electrical pulse signals; calculating the pulse frequency yields the instantaneous or cumulative flow rate of the fluid.
