VSE Circular Gear & Helical Screw Flowmeters

The VSE Volumentechnik Circular Gear and Helical screw positive displacement designs are ideal when high accuracy and resolution are required. Generally, they are used in two very different and distinct areas:

1) Testing components such as pumps, valves, cylinders and accumulators on hydraulic oils (mineral, synthetic or Ester based - Skydrol/Hyjet), fuels such as Avtur or water/glycol mixes.

2) Dispensing, mixing and pump ratio control of highly viscous glues, resins, paints and PU (Polyurethane) components such as Polyols and Isocyanates with or without fillers.

For these challenging applications UK Flowtechnik & VSE Volumentechnik have a range of innovative features such as Tungsten or Ceramic sleeve bearings, ‘D’ shaped shafts, ATEX, high pressure (700 Bar), DLC coatings, high temperature designs (to 210oC) and interpolation electronics which can give up to 128 times the resolution of a standard meter. Along with various fast output signal converters (FU-210) and panel mount displays (A341 & A350) designed specifically to be able to keep up with the extremely fast response and high frequency outputs (>100 kHz for some units) of the VS & RS ranges.

  • VS: Flows from 0.004 L/Min to 525 L/Min with typically a 1000:1 turn-down, Cast Iron or Stainless Steel bodies with Ball-Race or Sleeve bearings, up to 700 Bar pressure rating, ATEX, interpolation electronics and high temperature versions, the VS is the mainstay of our Circular Gear meter range.
  • EF: Primarily designed for OEM users and uses the same gears and bearings as the more capable VS range but in a more cost-effective body format. A two piece rather than the four-piece body of the VS and being manufactured from Aluminium allows this meter to meet OEM customers expectations without compromising quality or performance.
  • RS: Helical Screw flowmeters take over from the Circular Gear Meters when the going gets really tough i.e. when the viscosity increases to a degree that makes using a very large VS meter impractical, switching to a Helical screw solves the problem. Ranges go from 0.04 up to 3,000 L/Min, Cast Iron, Stainless Steel and high temperature versions RS flowmeters offer weight and cost savings over circular gear meters in certain applications.
  • VHM: Primarily designed for paints, these meters have a specially designed gear profile that can handle non-Newtonian, particle laden paints dyes and inks without becoming clogged. There are also ATEX versions as one would expect for volatile substances and also special models for coatings that are electrostatically charged.
