Flow switch SPKM for liquids vane type with an electric microswitch controlled by a moving magnet. The instrument is factory calibrated for horizontal flow. SPKM flow monitors operate on the principle of the paddle flow monitors. It is designed for installation in pipe systems. The spring-loaded paddle inside the device is moved by the medium flowing through it. A microswitch is actuated by means of a magnet. External measuring devices can be connected at the socket. However, the unit has a spring-loaded paddle that allows it to be mounted in any spatial position, including vertical. In this case, on-site calibration may be necessary to compensate for the weight of the paddle.
