CNG Dispenser Technology

The innovative technology developed by Compac ensures world-class performance, accuracy and safety for your dispenser.

KG80 Coriolis Mass Flow Meter

Using the Compac KG80 Coriolis Mass Flow Meter will bring some major improvements to the performance of your dispenser:601.jpg

  • No Calibration Drift – The dispenser automatically resets the zero point
  • Large Flow Range – The KG80 meter is accurate over the range 1-100kg/min and has been approved to the latest OIML standard: “Compressed Gaseous Fuel Measuring Systems for Vehicles”.
  • Meter Any Gas or Liquid – The mass flow measurement is independent of gas composition, humidity, temperature and pressure

Compac KG80 Meters are the most accurate CNG mass flow meters in the world. Compac has achieved a major advance in technology through the development of the KG80 Meter and its integration with the C4000 Electronic Head.

The KG80 Meter is a true mass flow meter using the physics of Coriolis forces to accurately determine mass flow. The KG80 Meter is self-characterising so that there is no meter set up and no measurements to be taken during commissioning.

The KG80 Meter has a rated working pressure of 275 bar (350 bar optional) and a burst pressure in excess of four times the working pressure. Compac has chosen the highest quality tubing and introduced some innovative manufacturing techniques to eliminate tube stress and corrosion over the life of the meter.

Hydraulic Module

Compac hydraulic components are made of pressure grade stainless steel for superior performance and corrosion resistance. They are batch numbered with traceability to material certificates and production runs. This ensures the correct grades of materials are used and the ratings of the valves can be guaranteed.

All hydraulic components have been independently tested and third party analysed to verify their structural safety.

All valves are assembled at Compac under strict quality procedures. These procedures have been audited and enable Compac to CE mark the valves.

The valves are designed to be reliable and easily serviced without removing pipework.

C4000 Electronic Head

603.jpgCompac C4000 is a highly accurate electronic head designed to control and manage the dispenser. The KG80 meter and all other electronic components plug directly into the C4000, which processes and calculates all required information.

During set-up and calibration, all parameters for the dispensers are set in the C4000.

The power supply for C4000 is housed in a separate flameproof, waterproof enclosure. This ensures additional safety to the dispenser and C4000 should any electrical fault occur.

Our Electronic Modules provide a world class, superior performance for your dispenser and include the following components:

  • KG80 Coriolis Mass Flow Meters
  • C4000 Micro-Processor Controller
  • C4000 Power Supply in a flameproof, waterproof enclosure
  • Three line displays with backlighting
  • Wiring loom including push-to-start and push-to-stop buttons
