VKA-Viscosity Compensated Flowmeter


  • Flow Ranges: 2...6.3 GPH to 8...26 GPM Oil
  • Media Viscosity: 30...540 cSt
  • Temperature Range: -13...212 °F
  • Max. Pressure: 3600 PSIG
  • All Brass Metal Bodies


Looking for a low cost viscosity compensated flowmeter? Look no further than the VKA line of meters! The VKA flowmeter combines proven and reliable construction with affordable pricing. Available for flow rates from 2 GPH to 26 GPM, the VKA is a viable alternative to the VKG and VKM series of flow metering products. Internal modifications reduce the pressure loss through the meter to 8 PSI, while still maintaining a compensated viscosity range of 30 to 540 cSt. Common uses include: lubrication circuits, paper manufacturing, hydraulics, extraction machines, and printing machines.
