Flux FMO 104 Series Oval Flow Meter


\Flux FMO 104 Series Flow Meter 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.

The FLUX name has been synonymous with pump technology for more than 60 years. It was the invention of the electric drum pump that sparked it all off. In the meantime, of course, technology has become more sophisticated. FLUX company innovations have markedly improved working routines for filling and transferring fluids. It is often said that medium-sized companies are the engines of progress. We would be pleased if our family business were able to substantiate this claim. When you choose FLUX you are making a good decision for the long term. With our products we want to assist you to save time and money and by the way ‒ spare your nerves as well. We are therefore delighted when you discuss your requirements with us.
