Viscosity-Compensated Flowmeters and Switches Model VKM Technical Details Body: Screwed fitting: Float: Orifice: Spring: Magnet: Seals: Max. temperature: Max. pressure: Electrical connection: Electrical switching values: Description The flowmeters and switches model VKM have a spring-loaded float, which slides within a cylindrical measuring 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 flowmeter and switch which fully compensates for viscosity and to a large extent for density...
