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.

The innovative GFM High Resolution flow meters combine the absolute measuring precision of proven gear flow meters with exceptionally high resolution, compact, integrated electronics. The precise mechanical measuring element supports the most dynamic possible measuring range with the lowest possible activation point.

Extraordinarily broad measuring ranges are realized and cascading fades into the background. The GFM High Resolution is therefore suitable for cost-reducing system designs and minimizes replacement part inventories.

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 gear dimensions and modules allows a wide range of sizes that can cover a huge measuring range
