A high pressure natural gas grid can have hundreds of transfer points where gas changes ownership, for example on delivery to large industrial users or to operators of city gates and domestic gas grids. At these transfer points the quantity, and sometimes the quality, of the natural gas needs to be accurately measured. KROHNE offers a modular control system to supervise this measurement and transfer the data to a central location, while maintaining high accuracy custody transfer standards and guaranteeing safe data communication.

KROHNE modular flow control and data transfer cabinets are built around the SUMMIT 8800 flow computer. Having a high quality and full colour touch screen, SUMMIT 8800 allows the operator to intuitively operate the metering control system, either from site or from a central control room. Due to the modular concept, up to six metering streams can be handled with a single cabinet and a single flow computer. The cabinets can be combined with any relevant 3rd party instrumentation.

The KROHNE expertise covers the entire design and manufacturing process, starting with a functional design specification, through detailed design, manufacturing and testing, up to commissioning in the field. After installation, KROHNE metering systems are supported by local offices or agents that are available in over 100 countries.


  • In-house KROHNE design, manufacturing and testing
  • Metering control cabinets are supplied fully wired, preconfigured and tested
  • Engineered to customer specification with customer preferred brands
  • In-house expertise to discuss custody transfer approvals with local metrology offices

Typical applications

  • Natural gas city gate applications
