ApplicationThe M&C flowmeters – type FM1 and FM10– which are corrosion-resistant are used forcontrolling the flow in case of aggressivegases and liquids. The flow tube is deliveredaccording to your specific data, e.g. medium,temperature, pressure.DescriptionThe M&C flowmeters FM1 and FM10 consistof a glass tube (the inside is conical andbecomes enlarged in the upper sector) inwhich the floating ball can move.The substance flows through the tube fromthe below part to the upper part so that thefloating ball is raised. It arises a gap betweenthe tube wall and the substance and createsan equilibrium. Each level of the floating ballcorresponds to a certain flow rate which isshown on the scale.The sealing and connecting parts are constructivelyreduced and consist only of in- andoutlet connection. All medium contactedparts are made out of PTFE and glass. Theflowmeter is configurated in such a way that itcan easily be dismantled and cleaned.
