The FLEX-FIN flow sensor monitors fluid media. Its compact form combines the measurement tube and converter / counter which, depending on the model, trigger an adjustable limit value with transistor output or an analog output (4..20 mA or 0..10 V) or both. In addition, the limit switch can alternatively be replaced by a frequency output or a Pulse output. The converter / counter record two process parameters: the flow speed of the medium and its temperature. Both parameters can be assigned to the analog output or to the switching output.
