Viscosity-Compensated Plastic Flowmeter and Switch for liquids



INSTROTECH is offering 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. Contact INSTROTECH for more information on Kobold’s VKP plastic flowmeters
