Rotary Piston Water Meter (Volumetric Meter)

A volumetric meter is the device fitted into a closed conduit ,which consists of chambers of known volume and a mechanism driven by the flow,whereby these chambers are successively fitted with water and then empited . The water to be measured enters the inlet of the body and its pressure sets the piston into rotation . Every rotational cycle of the piston discharge a fixed volume of water to the meter of body. The number of rotation of the piston is totalized through a reduction gear ,to totalize in the register , when the total volume of water is registered.
