The KOBOLD flow meters and switches model VKG have a spring-loaded float, which slides within a cylindrical measu- ring tube and has an integral orifice which is believed to be unique.
This and other design features means that it has for the first time become possible to create a flow meter and switch which fully compensates for viscosity and to a large extent for density even with very low flows. The float of these patented devices contain permanent magnets which actuate a poten- tial free bistable reed contact mounted outside the flow thus ensuring hermetic separation between the medium and the electrical contact system. The contact is embedded within a height-adjustable plastic housing to prevent damage to the contacts by mechanical action or aggressive atmospheres
