Kobold’s VKP plastic flowmeters 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 400 mm 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.
The devices’ measuring range extends from 2-20 to 20-100 l/min water, and 1-18 to 10-75 l/min oil and is accurate to ±5%. Its maximum temperature and pressure limits are 16 bar and 120°C respectively.
The unit is made from polysulfone material and accepts G1/2, and G3/4 soldering connections of 18 mm and 22 mm via a G1, 1” NPT PVC glue-in connection.
Suitable applications include lubricant circuits, domestic electrical installations, machine tools, solar energy systems, cooling circuits, welding machines, and pumps.
