Water turbine is a energy conversion device.

Flow through the water turbine acquired the potential energy,then converst into mechanical energy. The turbine rotor drives the rotor of the generator,concerting mechanical energy onto electrical energy. 

According to the water head and water flow,the micro water turbine can be divided into many types.

1.Low head from 1.2m to 20m

2.Mid head from 15m to 40m

3.High head >25m
