KRAL Flowmeters OMS Series.

Stainless steel design for demanding media.

When selecting a flowmeter for demanding media, the issue of material resistance always arises. The OMS series is a stainless steel design for low and high viscosity media, equipped with ball bearings or plain bearings depending on the application.

Your benefits.

  • High precision
  • Extremely robust
  • Stabilization zones unnecessary
  • Low friction and minimal loss of pressure
  • Very compact design.

Application examples.

  • Dosing of resin, paints, adhesives
  • Coating of propellers in wind power turbines
  • Insulating materials
  • Greases and waxes
  • Water volumetric flow measurements.

Materials.

  • Housing: Stainless steel
  • Screws: Stainless steel (coated for high viscosity media)
  • Bearings: Ball or sliding bearings
  • Gasket with ball bearings: Viton®
  • Gasket with sliding bearings: Teflon®.
