Fiscal metering of the CBG your plant sells
When a CBG plant sells gas, the producer and the buyer need one measurement both can rely on for billing. CRA's custody transfer metering skids measure the CBG leaving the plant, with the meter, flow computer, filtration and isolation on one skid, built to the metering requirements of the buyer and the applicable standards.

What is a custody transfer metering skid?
A custody transfer metering skid measures gas at the point where it changes hands, so that the seller and the buyer bill against one agreed figure. At a CBG plant it sits at the outlet, after compression or before pipeline injection.
How it works
The gas passes through filtration and the meter, and the flow computer records the quantity sold.
The gas is filtered to protect the meter.
The meter measures the flow of gas leaving the plant.
The flow computer works out the quantity delivered for billing.
Isolation valves allow the meter to be taken out for maintenance.
The flow computer can report to the plant control system.
