FLOMEC® Medium Capacity Flowmeters provide precise volumetric flow measurement of clean liquids found in a broad range of industries including automotive, aviation, mining, power, chemical, pharmaceutical, food, paint & petroleum.  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.



FLOMEC®  meter options include integral LCD totalisers, flow rate totalisers & batch controllers. These instruments provide monitoring & control outputs including 4~20mA, scaled pulse, alarms & batch control and are also available with robust mechanical registers:

  • BT LCD 5 digit reset, 8 digit cumulative totaliser.
  • RT12 LCD 6 digit reset, cumulative totaliser & flow rate. Analogue and Pulse Outputs
  • RT40 LCD 6 digit reset, cumulative totaliser & flow rate. Backlit Display
  • EB LCD 6 digit 2 stage batcher & cumulative totaliser.
  • M / V*  = Mechanical registers ( see model numbering )

(Instruments also available for remote mounting and with I.S. approvals)



  • Aluminium  meters are used for petroleum product      including oils and grease, fuels and fuel oils.
  • Stainless steel meters are for the chemical, water based liquids or where aluminium is not suited or permitted.
  • Blind pulse meters are available with reed switch & Hall Effect outputs. Quadrature pulse & Integral 4-20mA outputs are optional.


  • 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)
