The water flow indicator is used to easily check the correct flow rate of the cooling water for the power electronics, blade drive motor and diamond saw blade. It can be integrated directly into the water supply to the wall saw by means of GeKa hose couplings. In the case of the WSx-296, WS-296 and WS-451 EE high-frequency wall saws, it makes sense to connect the flow indicator at the water inlet to the high-frequency controller.
