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

The Flomec® Medium Capacity Flow Meters provide precise volumetric flow measurement of clean liquids found in a wide range of industries including: automotive, aviation, mining, power, chemical, pharmaceutical, food, paint & petroleum. 

Suitable applications include the: distribution of fuels, fuel oils, lubricants, alcohols, solvents, blending of bio & ethanol fuels, metering of chemicals, grease, adhesives, ink, insecticides & non-conductive liquids either pumped or gravity fed non-conductive liquids.

NMI Approved Meters

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

Features

  • High accuracy & repeatability, direct reading flowmeter
  • No requirement for flow conditioning ( straight pipe runs )
  • Various rotor material options
  • Measures high & low viscosity liquids
  • Quadrature pulse output option & bi-directional flow
  • Integral 4-20mA output option
  • Optional Exd I/IIB approval (ATEX, IECEx)
