Metering and Pipeline Injection for CBG
Custody transfer metering and pressure reduction skids for selling CBG and delivering it into pipelines.

Measured, regulated delivery of CBG
CRA's metering and pressure reduction skids measure the CBG a plant sells and deliver it into city gas and industrial pipelines at the network's pressure.

How is CBG metered and delivered into a pipeline?
At the point of sale, a custody transfer meter and flow computer record the gas delivered to the buyer. Where the gas goes into a pipeline, a pressure reduction skid first filters it, then lowers its pressure through regulators to the network's level, with safety shut-off valves and relief to protect the network. The gas is metered on its way in.
How it works
The skids sit at the plant boundary, between the compression stage or the cascades and the buyer's connection.
Filters remove particles before the meter and regulators.
Regulators bring the gas to the network's pressure.
Safety shut-off valves and relief guard against over-pressure.
The meter and flow computer record the gas delivered.
The CBG enters the buyer's pipeline or network.
Key Benefits
Custody transfer metering gives the producer and the buyer one figure to bill against.
Regulators bring the gas to the pressure the network needs.
Safety shut-off and relief protect the network from over-pressure.
Each skid follows the metering and network requirements of the receiving party.
Meter, flow computer, filtration and regulation come packaged on skids.
Projects That Push Boundaries
Purpose-built for remote dairy site conditions with gas delivery to a distant utilisation point.

Frequently Asked Questions
What is custody transfer metering?
It is metering at the point of sale, to a standard the producer and the buyer both accept, so both can bill against one figure.
What does a pressure reduction and metering skid do?
It filters the gas, brings it to the network's pressure, protects the network with safety shut-off and relief, and meters the gas delivered.
Can the skid take gas from cascades?
Yes. CRA designs pressure reduction skids for the inlet pressure range, including decompression from CBG cascades.
What data does CRA need to size CBG metering and injection skids?
CRA needs the gas flow range, the inlet and outlet pressures, the requirements of the buyer or network operator and the site conditions.
Which meter types does CRA use?
CRA supplies skids with the meter type the duty and the buyer call for, and confirms the choice with the gas data.
