Flow Measurement Products

Highly accurate flow measurement products designed to be maintenance free and provide long term stability with a lifelong guarantee on the functionality of the metering section.

Flowcom 3000 flow metering system in Orca truck

Flowcom 2000 and 3000 metering system calculates flow rates of various media by measuring the pressure difference across a restricted orifice. Density compensation is achieved by either temperature or a combination of pressure and temperature.


  • Maintenance free - no moving parts in metering section
  • Long term stability - high end sensor technology 
  • Ergonomic design - colored graphics for easy to read display and keyboard for ease of operation
  • Internal data memory for >4000 deliveries
  • Bluetooth communication for automatic data transfer
  • 'PumpSmart' built-in pump protection logic reduces maintenance costs and protects against expensive pump failures

This unique design is patented and patent-pending in multiple countries and features a thermally insulated pre-cooled meter with a built-in phase separator.

Highest standards of engineering, programming and manufacture - all processors, including software and electronics, are developed in-house by our own engineers and manufactured in Germany. The metering systems are assembled at the factory in Monheim am Rhein.

Approved by European Measuring Instruments Directive (MID), International Organization of Legal Metrology (OIML), Physikalisch Technische Bundesanstalt (PTB Germany) and many other country specific control bodies.

Principal applications:

  • Installations on road tankers and tube-trailers
  • Stationary loading applications e.g. transport trailers, railroad cars
  • Fuel dispensers and fueling stations

FLOW metering systems are available for a wide variety of products including liquefied air gases (nitrogen, oxygen and argon), CO2, hydrogen, liquid petroleum gases (LPG) and AdBlue.

Standard range covers the following flow rates:

  • Flowcom 3000 for liquid nitrogen, argon, oxygen, carbon dioxide and LNG - 1000 to 75,000 kg/hr (2200 to 165,000 lb/hr)
  • Flowcom 2000 for AdBlue - 20,000 to 100,000 kg/hr (44,000 to 220,000 lb/hr)
  • Flowcom 2000 for propane and butane (LPG) - 10,000 to 25,000 kg/hr (22,000 to 55,000 lb/hr)
  • Flowcom 2000 for gaseous hydrogen - 1 to 20 kg/min (2.2 to 44 lb/min) with pressures from 30 to 210 bar

Customized solutions and special applications available on request.

Comprehensive aftermarket package that includes parts and service, routine maintenance, calibration, installation and operator training.
