Electromagnetic flow meter FLONET FH20xx is intended for flow-rate measurements of conductive liquids in water and heat supply systems, chemical, food processing and other industries. They meet the most stringent requirements on measurement accuracy, long-term stability and hygienic standards. Flow-rate measurements in both directions of flow are possible. The meter sensor has no movable mechanical parts and its inclusion in the piping system will have no effect on the hydraulic or pressure flow conditions. The converter unit provides for sensor energizing and processing in the sensor energizing and processing of the sensor signals. The meter has pulse and current outputs, as well as interface to the HART communication protocol. The information is displayed in English.
