Count on Flow

High quality measuring systems, worldwide service network and on-site calibrations. Flow measuring systems for mobile delivery units, stationary filling systems and LNG and hydrogen vehicle fueling.

Flow Expertise

Every year Flow produces > 1000 durable, reliable and efficient measuring systems and undertakes > 3000 calibrations at customer sites. Already a significant player across Germany and Europe, Chart's global network has enabled successful expansion into Latin America, Malaysia, China, Russia and the Middle East.


We come to you - FlowMass is a mobile calibration system that allows us to recalibrate all different types and brands of flow meters accurately and at your site, saving you time and money. A typical calibration with FlowMass takes only 45 minutes.

Total Service

Our commitment to service is absolute. Complete aftermarket packages include periodic calibration and accuracy verification of flow metering devices together with routine maintenance, operator training and installation as required.

MiniBulk Distribution System (MBDS)

Specifically designed for fast filling of CO2 tanks in city center and residential areas where access is restricted to conventional tankers and/or associated noise pollution is a nuisance or prohibits deliveries out of hours.


DynaFlow® 3000

Fast, accurate and reliable fueling of LNG vehicles.


Flow Measurement for Mobile Delivery Units

Flow measuring systems are CE marked and approved by European Measuring Instruments Directive (MID), International Organization of Legal Metrology (OMID), Physikalisch-Technische Bundesanstalt (PTB Germany) and other relevant country specific control bodies.

The Flowcom® 3000 Flow Meter System is at the heart of our measuring devices for liquid nitrogen, argon, oxygen, carbon dioxide and LNG. The metering section contains no moving parts, is maintenance free and comes with a lifetime guarantee.

  • Measures standard flow rates from 1,000 to 75,000 kgs/hr (2,200 to 154,000 lbs/hr)
  • Internal memory capable of logging more than 4000 deliveries
  • Bluetooth transfer of individual data records
  • Back-up system preserves data even in the event of a total power failure
  • Pump Smart feature regulates pump cooling times to protect against pump failure

cryogenic flow measurement

The Flowcom® 2000 Flow Meter System is the industry leading flow measurement device for AdBlue, LPG and hydrogen. It shares many of the standard features of the Flowcom 3000 plus the following special adaptations:

  • AdBlue standard flow rate 20,000 to 100,000 kgs/hr (44,000 to 220,000 lbs/hr)
  • LPG standard flow rate 10,000 to 25,000 kgs/hr (22,000 to 55,000 lbs/hr)
  • Gaseous hydrogen standard flow rate 1 to 20 kgs/min (2.2 to 44 lbs/min)
  • Gas bubble sensor, optional automatic valve and 2-phase mixture detection for increased measurement accuracy
