Accurate, repeatable flow measurement for custody transfer and process accounting
CRA’s Metering Skids are modular, skid-mounted systems engineered for precise and repeatable flow measurement in gas and liquid services. These systems integrate flow meters, piping, flow conditioning, instrumentation, and controls into a compact, ready-to-install package. Designed for custody transfer and process measurement, CRA metering skids deliver high accuracy, long-term reliability, and compliance with international standards across onshore and offshore applications.

What is a Metering Skid?
A metering skid is a modular, skid-mounted system that measures gas or liquid flow with the accuracy and repeatability required for custody transfer, allocation, and process measurement, integrating the flow meter, flow conditioning, instrumentation, and controls into a single ready-to-install package.
How it works
Fluid passes through upstream conditioning to establish a stable velocity profile, then through the meter itself, before the flow computer calculates a corrected reading.
Gas or liquid passes through straight pipe runs, flow conditioners, and filtration that establish a stable velocity profile before reaching the meter.
Meter technology, ultrasonic, turbine, Coriolis, or positive displacement, is selected based on the fluid, flow range, and accuracy class required, then measures the conditioned flow.
Pressure, temperature, and density inputs combine with the flow signal in the flow computer to calculate corrected volume or mass flow.

Frequently Asked Questions
What is a metering skid used for?
A metering skid provides precise, repeatable flow measurement for gas or liquid service, most commonly for custody transfer, allocation, or process accountability where accuracy directly affects billing or mass balance. CRA integrates the flow meter, flow conditioning, piping, instrumentation, and controls into a single ready-to-install package.
What metering technologies does CRA use?
CRA selects from ultrasonic, turbine, Coriolis, and positive displacement (PD) meters depending on the fluid, flow range, and accuracy class required by the application, rather than defaulting to one metering technology across every project. Flow conditioning is engineered upstream of the meter to reduce measurement uncertainty.
What's the difference between custody transfer and process metering?
Custody transfer metering measures gas or liquid changing legal or commercial ownership and must meet defined accuracy and audit requirements, while process metering supports internal monitoring, allocation, or energy and mass balance without the same regulatory accuracy class. CRA metering skids are engineered to meet custody transfer requirements where that's the application, and scaled appropriately for process-only duty.
What standards do CRA's metering skids meet?
Metering skids are engineered to meet ASME, ISO, and applicable custody transfer requirements for the destination market, covering meter accuracy class, piping, and installation geometry. The specific code set depends on whether the application is custody transfer, allocation, or internal process measurement.
Where are metering skids typically installed?
Common installations include pipeline flow measurement stations, terminal and tank farm metering, refinery and petrochemical metering, utility and distribution flow monitoring, and allocation or production measurement points onshore and offshore. CRA engineers each skid for the specific fluid and site conditions rather than a standard configuration.
