Volume flow sensor

The measurement principle of the FTS electronic volume flow sensor is based on Karman vortex streets. An obstructing body projecting into the flow generates eddies. These are detected by a piezoelectric paddle and evaluated by the integrated electronics. A microprocessor converts the analogue measurement values into a serial digital signal suitable for the DL bus.
