The WIKA electronic flow switch with display is full flexibility in monitoring and controlling flow based on the velocities of liquid media. The switch points of the model FSD-4 can be freely configured very easily via the 3-button operation directly on the instrument or optionally via IO-Link. The model FSD-4 can output both absolute values in various units and relative flow values and display them on the digital indicator.

Wear free flow monitoring of liquid media using them calorimetric principle
Flexibly configurable switching and analogue outputs for flow and temperature
Exact adaptation to the conditions on site
