Details
The switch is designed for the safe monitoring and display of relative mass flow rates of liquid media in hygienic applications, for example the monitoring of cooling water circulation systems and filter monitoring in the beverage industry. It can be selected between one or two switch outputs as well as one switch output and one standardized analog output for flow rates or temperature values. A variety of hygienic process connections leads to a flexible use
