Flow sensors or flow measurements

Type: S-MEFS-K



For use in air-conditioning and ventilating plants, heating installations and the whole range of industrial facilities. With its two configurable limit value contacts, the integrated display and its numerous electrical connections, the flow sensor for flow measurements is also suitable for applications with higher requirements.


By means of a sensor element and auxiliary energy a temperature difference is used to convert the actual flow velocity into an electrical standard signal.


This electric signal changes in proportion to the flow velocity and can be further processed.
