VKP Viscosity Compensated Flowmeter/Switch
Brand: KOBOLD Instruments, IncThe KOBOLD plastic flow meters model VKP operate on a special suspended float principle with cylindrical measuring tube and spring-loaded float with orifice.
The float in model VKP-3 has slots moulded on the outside, which protect the instrument from soiling by depositing dirt particles. The danger of the float jamming is thus considerably reduced and soiled liquids with a particle size up to 400 μm can be measured without difficulty.
In model VKP-2 a sharp-edged orifice in the float renders the instrument less sensitive to changes in viscosity.
