Oil Storage, Metering & Loading
Custody-Transfer Metering Skids
Custody-Transfer Metering Skids for fiscal or allocation measurement of liquid hydrocarbon transfers through one or more instrumented meter runs. Review process cases, metering or storage basis, safety functions, interfaces, approvals and test records before requesting a comparable quotation.
RFQ selection reference
Reference fields for quotation comparison. Final values must be confirmed in the signed manufacturer datasheet.
| Selection field | Typical input | Typical input | Typical input | Buyer note |
|---|---|---|---|---|
| Flow envelope | Minimum, normal, maximum and upset rate | Fluid properties, pressure and temperature | — | Provide operating cases and uncertainty budget |
| Meter runs | — | Technology, size, class, runs and turndown | Proving, density and sampling interfaces | Define redundancy and maintenance bypass |
| Automation and assurance | Accuracy, repeatability and calculation basis | — | Flow computer, ESD, communications and approvals | State FAT, calibration and witness requirements |
Product scope
Custody-Transfer Metering Skids are presented as a quotation-ready equipment family for fiscal or allocation measurement of liquid hydrocarbon transfers through one or more instrumented meter runs. This page supports technical offer comparison; it does not promise one model, inventory position, measurement performance, regulatory approval or certification. The selected manufacturer and system integrator must confirm the equipment against the process duty, custody contract, site regulations, interface drawings, governing standard editions and signed datasheet.
Selection basis
The main RFQ inputs are fluid phase and composition, flow range and turndown, pressure and temperature, density and viscosity range, gas or solids risk, line size and pressure class, meter technology, required uncertainty and repeatability, number of runs and redundancy, proving connection, master-meter or compact-prover method, flow computer, pressure/temperature/density inputs, sampling, valves and strainers, ESD, bypass philosophy, hazardous-area class, communications, calibration, witness testing and local approvals. Storage, metering and loading equipment cannot be selected from nominal line size or capacity alone. Provide normal, minimum, maximum and upset process cases, fluid analysis, site environmental data, piping and instrumentation diagrams, plot plan, utility schedule, control and shutdown philosophy, legal-metrology jurisdiction, terminal or custody agreement and all mechanical, electrical and civil interfaces. For expansion work, include existing equipment records and measured tie-ins.
Trade and industry context
The cited UN Comtrade record is a broad tank, instrument or handling-equipment export proxy used only to prioritize internationally traded product families. It is not an oilfield-only market size, a search-volume estimate or a shipment claim for this equipment. API references identify relevant storage and measurement practice boundaries; they do not prove that an unnamed supplier is licensed, certified, legally approved or holding stock.
Documents and inspection
Define signed process and mechanical datasheets, calculations, PFDs and P&IDs, general arrangement and tie-in drawings, civil and structural loads, material certificates, welding procedures and NDE, tank or piping tests, instrument calibration, uncertainty budget and proving records where applicable, hazardous-area certificates, functional safety or cause-and-effect tests, FAT/SAT, coating records, certificate of conformity, manuals and spares. Verify the manufacturer, integrator, calibration traceability, certificate scope, local approvals and standard editions before order release.
RFQ checklist
- •Equipment family, quantity, capacity/flow and delivery target
- •Fluid properties, pressure, temperature and normal/upset cases
- •Measurement accuracy, proving, sampling and legal requirements
- •Tank, pipe, civil, power, control and hazardous-area interfaces
- •Materials, corrosion, inspection, calibration and test records
- •Destination, Incoterm, module size, lifting and transport limits
- •Target unit or package price and acceptable technical alternatives
Upload the process datasheet, P&ID, site layout, custody or terminal requirements and project specification with the inquiry. Close every process, metrology, safety, interface and regulatory deviation before comparing price or releasing the order.

Frequently Asked Questions
What information is required to quote Custody-Transfer Metering Skids?
Provide fluid phase and composition, flow range and turndown, pressure and temperature, density and viscosity range, gas or solids risk, line size and pressure class, meter technology, required uncertainty and repeatability, number of runs and redundancy, proving connection, master-meter or compact-prover method, flow computer, pressure/temperature/density inputs, sampling, valves and strainers, ESD, bypass philosophy, hazardous-area class, communications, calibration, witness testing and local approvals, quantity, destination, delivery target and required records. Attach process data, P&IDs, layouts and the applicable custody or terminal requirements.
Does an API reference make the package legally approved for custody transfer?
No. API measurement practices are only part of the design basis. The buyer must define the governing contract, standard editions, legal-metrology jurisdiction, calibration traceability and local approvals.
How should alternative packages be compared?
Compare the same process cases, uncertainty or performance basis, materials, interfaces, safety functions, tests, calibration, documents, site scope and all technical or regulatory deviations before comparing price.
