Flow Switches

Flow switches are mechanical switches that are switched on or off by the flow or non-flow of a liquid. Flow switches might be used to monitor the flow rate of a liquid and trigger an alarm if the flow is too high or too low. The flow sensor will usually send an electrical signal to a controller.

    Based on the thermodynamic principle, this flow switch features two temperature sensors inside the probe: one is for the medium temperature into which it projects, the other one is heated a few degrees above the medium temperature. When the medium flows, the heat generated in the sensor is diffused by the medium. The difference between these two sensors is used to measure flow rate.

    It comes in all-metal housing and is suitable for a variety of pipe diameters.
