EUV 50 AI – EUV 1000 AI automatic control devices, pipe diameter from 2” to 40”, are designed for applications with wide range of flow rate that changes irregularly. The optimum mode is set automatically by the flow meter’s signal or by a flow sensor in accordance with actual flow in the piping. The signal from the metering device is in metric and is equal to 1 impulse/litre. The type of the used sensor must be specified with the order form. Metering devices other than metric can be supplied on request and must be specified with the order.
