Metering Systems

OGS supply Fiscal Metering Systems, Allocation Metering and Custody Transfer Metering Systems for a wide range of fluids including oil, gas and condensate. Typical applications include production, transmission/distribution pipelines, import/export for oil, gas and LNG terminals and storage facilities.

Let's go!

Our systems are provided compliant with DECC & NPD requirements for fiscal measurement requirements in the UK and Norwegian sector of supply

Our computation and reporting packages can range from simple flow computers to full supervisory systems with graphical control functions and communication with DCS, ICSS or other systems.

All of our systems are built, assembled and flow tested at our own fabrication facilities in Swansea (UK).

Metering Systems

Bi-Directional Provers

A bi-directional prover is one of the most reliable means available to verify meter readings and establish meter factors. It is an easy and accurate way to calibrate meters in the field, in order to ensure exact measurement of liquid flow.

Compact Provers

OGS can supply Compact Provers, SVP (small volume provers) that use double chronometry pulse interpolation for flow meters (turbine positive displacement, coriolis and liquid ultrasonic meters).
