Viscosity-Compensated Plastic Flowmeter and Switch for liquids

Kobold’s VKP plastic flowmeters that 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 mounded onto the outside, which protect the instrument from soiling by “capturing” dirt particles.  The danger of the float jamming is thus considerably reduced and soiled liquids with a particle size up to 400mm can be measured without difficulty.  In model VKP-2, the sharp-edged orifice in the float renders the instrument less sensitive to changes in viscosity. 

VKP specs at a glance:

  • Measuring range: 2-20 … 20-100 l/min water; 1-18 …10-75 l/min oil
  • Accuracy: +5% of full scale
  • Pressure: maximum 16bar; temperature: maximum 120°C
  • Connection: G1, 1” NPT PVC glue-in connection, inserts G1/2,G3/4 soldering connection 18mm, 22mm
  • Material: polysulfone

The model VKP finds application in lubricant circuits, domestic electrical, installations, machine tools, solar energy systems, cooling circuits, welding machines, and pumps.
