There are several critical components which are included in every Compac CNG Dispenser to ensure their performance and accuracy every fill.  These include:

• KG80 Coriolis Mass
• C4000 Electronic Head
• Hydraullic Components

Each of these components have been specifically designed and developed by our highly innovative engineers.  Every single item is tested and quality assured before it is allowed to be included in any of our dispensers or dispenser modules.

This is the only way we can safely guarantee the quality and performance of all the Compac components.  That’s how you know you are buying a world-class dispenser.

Dispenser Technology Product Guide

KG80 Coriolis Mass Flow Meter
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 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.

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

• No Free Gas – Highest possible accuracy.  True error checking between meter and dispenser electronics prevents dispensing un-metered gas
• No Calibration Drift – The dispenser automatically resets the zero point
• Large Flow Range – The KG80 meter is accurate over the range 1-80kg/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

C4000 Electronic Head

Compac 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 the C4000 is housed in a separate flameproof, water proof enclosure.  This ensures additional safety to the dispenser and the C4000 should any electrical fault occur.

Hydraulic Components
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 and are tested on CNG.  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.
