Flux Flow Meter FMO 101

Flux Flow Meter FMO 101

The flow meter FMO 101 built according to the oval rotor design is suitable for measuring pure, thin to highly viscous media. With the evaluation unit FLUXTRONIC® filling and dosing processes of almost all kinds of fluids can be performed with maximum precision and highest safety.

In automatic mode it is possible to output a signal for control purposes with the evaluation unit and the use of a switching amplifier.  This way e.g. motor and / or magnetic valve and the most different processes can be controlled.

The housing parts of the flow meters FMO form a measuring chamber in which the oval rotors mounted on axes can turn. The fluid flows through the measuring chamber and thus actuates the oval rotors. By the means of a Reed sensor the number of rotations is counted and forwarded as an impulse or passed on to the evaluation unit FLUXTRONIC®. This calculates the flown through quantity of the fluid based on the previously entered, medium-dependent calibrating constant.
