Measurement of liquids up to 180 °C. Process cooling in an induction furnace. Mechatronic flow sensor The flow sensor works to the principle of spring-support- ed piston: the piston, located in the valve seat in the housing, is lifted by the flowing medium against the spring resistance. The piston position is monitored via a magnetic-field sensor and is output as an analogue signal. The spring resistance forces the piston to return to its original position with decreasing flow. This ensures posi- tion-independent installation of the flow sensor preven- ting backflow.
