What Is The Impeller Type Flow Meter?

- Jul 17, 2019-

The working principle of the impeller type water flow sensor is that the impeller is placed in the fluid to be measured, and is rotated by the impact of the fluid flow, and the flow rate is reflected by the speed of the impeller rotation. Typical impeller flow meters are water meters and turbine flow meters, which may be of mechanical transmission output or electrical pulse output. Generally, the water meter output of the mechanical transmission has low accuracy and the error is about ±2%, the structure is simple and the cost is low. The domestic production has been mass-produced, standardized, generalized and serialized. The accuracy of the turbine flowmeter for electrical pulse signal output is high, with a typical error of ±0.2% to 0.5%.


Shenzhen EPT Technology Co.,Ltd, a Chinese manufacturer of hall flow sensor for over 16 years. The hall flow sensor application includes water cooler, coffee machine, water dispenser, water purifier etc smart home application instruments.  This flow sensor is suitable for small flow rate application, but the flow accuracy is up to 2%. What's more, the flow sensor meets food grade standard. If you have any interest, welcome to visit our Website: http://eptsensor.com
