description
The effectiveness of the flow sensors is based on the
calorimetric principle. The measuring probe is heated by a
few degrees (Celsius) above the temperature of the
medium. Heat is conducted through the medium flowing
past it. The difference in temperature between the medium and the sensor is a measure for the flow condition which
occurs. A corresponding switch signal can be assigned for
a specific flow condition using the potentiometer of the
integrated amplifier electronics.
With the settable turn-off delay, the relay remains in its
initial state if there is a short-term dip in the flow. It is possible to identify when a specific temperature is exceeded
or not using a second built-in relay.
Assembly can take place regardless of the direction of flow.
A basic principle is to make sure that the pin of the sensor
is completely surrounded by the medium which is to be
monitored not only when idle but also when flowing. In the
case of small cross sections, care should be taken that the

tip of the measuring head does not fundamentally constrict
the cross section of the pipe. Instable flow forms cause
malfunctions. In order to avoid this, no installation parts
influencing the cross section or the direction of flow should
be fitted directly in front of and/or behind the sensor. The
rough guideline value for this inlet/outlet path is approx. 8
times the diameter of the pipeline.

application examples
protection against the dry running of pumps
continual monitoring of the presence of a flow of fluids
additional temperature monitoring of the different
media
monitoring of filters and sieves
assuring the circulation of cooling water to automated
welding systems
