Packages · Metering & Analyzer
A meter-proving system tests a process meter against an agreed measurement reference or proving method under defined conditions. Prover or reference type, flow range, reference conditions, uncertainty target and acceptance criteria are established from the approved project basis; no generic numerical performance is assumed.
From project definition to delivery
Engineering of Meter Proving Systems concentrates on required measurement uncertainty, fluid properties, operating range, meter-run geometry, pressure loss, flow conditioning, calibration or proving, compensation and audit-trail integrity. The selected configuration is verified against normal, minimum, start-up, shutdown and credible upset cases, then checked for operability, maintainability, energy use, process safety and site interfaces before the design is frozen.
Flow range and reference conditions, the type and number of meters under test, fluid properties, prover or reference arrangement, test method, and repeatability and uncertainty criteria are agreed before the design is frozen. Connections, bypasses, pressure-drop limits, result recording and operating conditions are documented in the approved project records.
Materials, corrosion allowance, sour-service requirements, piping classes, nozzle design, insulation, coating, supports and maintenance access are coordinated with the actual process conditions and project code hierarchy.
Control philosophy, alarms and trips, cause-and-effect logic, interlocks, start-up and shutdown sequences, safe depressurization and operator access are developed consistently from the P&IDs through functional testing.
Battery limits, tie-in points, structural loads, cabling, instrumentation, drains, vents, access routes, lifting envelopes and shipping constraints are controlled through coordinated models and interface drawings.
From project definition to delivery
Proposal quality depends on complete input data and an explicit acceptance basis. The following lists provide a practical starting point and are completed during technical clarification.
Technical Datasheet
These are model-series examples for liquid compact provers, not a universal proving-system range or accuracy guarantee.
| Parameter | Published model-series values | Basis / secondary data | Application limit |
|---|---|---|---|
| Maximum prover flow | 1,350–5,565 m³/h | Published compact-prover model sizes; model maxima are not a single-unit operating band. | Confirm prover size, fluid, pipe/flange class, meter range, proving frequency and applicable API procedure for the installation. |
| Displaced volume examples | 50–168 US gal primary volume | Published primary displacement across representative prover models. | Selected volume and pulse resolution must satisfy the applicable proving design and uncertainty requirements. |
