Viscosity-Compensated Plastic Flowmeter and Switch for liquids

The float in the Kobold’s VKP has slots mounded onto the outside, which protect the instrument from soiling by “capturing” dirt particles. The danger of float jamming is thus considerably reduced and soiled liquids with a particle size up to 400mm can be measured without difficulty. The Kobold’s VKP, the sharp-edged orifice in the float renders the instrument less sensitive to changes in viscosity.

Kobold’s VKP specs at a glance:

• Measuring range: 2-20 … 20-100 l/min water; 1-18 …10-75 l/min oil
