FLOMEC®  Large Capacity Flowmeters are suited for receipt verification, loading, un-loading & distribution management at petroleum depots, mine sites, marine & aviation facilities. Common transfer applications involve fuels, oils, solvents, alcohols along with the blending of bio & ethanol fuels either pumped or gravity fed. The meters are compact & light weight in construction, important benefits when used in mobile installations or within confined spaces.



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)
