GFM High Resolution

for the exact dosing and measuring of extremly small quantities

The special design of the GFM High Resolution series flow meters is tailored for measuring and dosing extremely small quantities. They are ideal as meters in test stands and for applications where great flexibility with optimum measuring performance is in demand. Lubricating as well as non-lubricating, abrasive, aggressive and filled media across a very broad viscosity range can be measured precisely and reliably.

Only high-grade steels and alloys that even withstand corrosive liquids are used in the production of GFM High Resolution flow meters. Combined with the use of tungsten carbide bearings, the GFM High Resolution guarantees optimum measurement accuracy and a long service life under even the toughest application conditions. Stainless steel bearings guarantee smooth start-up behavior, even with very small volume flows and low-viscosity media. The combination of various gearwheel dimensions and modules supports a broad range of design sizes, covering an enormous measuring range.
