Flow sensors and transmitters
ifm flow sensors and transmitters are solid state alternatives to mechanical flow switches for sensing the flow rate of liquids and gases. Because there are no moving parts to jam or break, ifm efector flow sensors eliminate the maintenance headaches of mechanical flow switches.
