Electronic flow monitor, PN 100
Application: The electronic flow monitor monitors liquid media continuously. Its application can be seen wherever flows need to be monitored with minimal pressure loss. The single-piece version of the measuring pin reduces the sensitivity to contamination to a considerable extent. The electronic flow monitor works as per the calorimetric principle. The front face of the sensor is heated up to a few degrees over the temperature of the flow media. When the medium flows, the heat generated in the sensor is dissipated, i.e. the sensor is cooled. The cooling process is a perfect measure of the speed of flow.
The sensor signal is compared with the reference data stored in the micro-controller. Differences between the desired and actual values of the speed of flow trigger off an output signal.
