Positive Displacement Large Capacity Flow Meter by FlowmecFor precise volumetric flow measurement of clean liquids

The Flomec®  Large Capacity Flowmeters are suited for receipt verification, loading, un-loading & distribution management at petroleum depots, mine sites, marine & aviation facilities. The most common transfer applications involve fuels, oils, solvents, alcohols along with the blending of bio & ethanol fuels either pumped or gravity fed.

These meters are compact and light weight in construction - important benefits when used in mobile installations or within confined spaces.

NMI Approved Meters

Meters 1" and above are available with optional NMI pattern approval and quadrature pulse output.
