Application of damper

Application

Cavitation, liquid hammer and pressure peak may occur in air or hydraulic systems with varying flow rates, such as the rapid closing of valve or the start and stop of pump. Even at relatively low operating pressures, these problems may occur at the entrance and exit.

Installation

If the fluids containing particles, then nozzle clogging maybe occur, and the vertical installation of the transmitter minimizes the risk of clogging.
