General functional descriptions

Flow meters

FMC 100, FMJ 100, FMC 250

The flow meters FMC 100, FMJ 100 and FMC 250 work on the nutating disc principle. Here the liquid flow makes the nutating disc move. The evaluation unit FLUXTRONIC® calculates the filled quantity from the number of rotations. For maximum measuring accuracy the system must always be completely filled with liquid (full hose system).


The turbine meter FMT 50 PP consists mainly of a turbine wheel freely rotating in the liquid flow. The medium flowing in the flow meter makes the turbine wheel turn, this is measured and evaluated. The evaluation of the partial and total quantity is made via the LCD display.

FMO 101, 102, 104, 110, 140, 150

The flow meters FMO 101, 102, 104, 110, 140 and 150 consist of a measuring chamber with oval rotors. The fluid runs through the measuring chamber and thus drives the oval rotors. With a REED sensor the number of rotations is counted and passed to the external FLUXTRONIC®. This calculates the flow quantity of the fluid on the basis of a previously given, medium dependent calibration constant.
