Terminal Loading, Metering & Tank Gauging
Transfer and measurement systems for liquid and gas terminals. State the loading arrangement, measurement purpose and shutdown interfaces as separate parts of the request.
Loading arms and transfer couplings
Loading arms provide an articulated fluid-transfer connection, while transfer couplings join the mating interfaces. The arrangement accommodates specified movement between a loading installation and a vehicle or vessel.
Road, rail and marine terminals use different transfer systems. Product properties, transfer rate and vehicle or vessel geometry influence selection.
Arm configuration, connection type, operating envelope and release features vary. State the required controls, bonding interfaces and inspection documentation.
Custody transfer metering skids
Custody-transfer metering skids combine measurement equipment for a specified commercial transfer. Meter runs, flow computation and supporting devices are selected to an agreed measurement basis and uncertainty requirement.
Terminals, pipelines and product-transfer facilities use these systems for defined liquids or gases. Fluid properties and operating range affect the measurement method.
Meter technology, proving, sampling and controls differ by project. Identify calibration, acceptance and integration responsibilities within the package.
Meter provers and calibration accessories
Meter provers and calibration accessories support comparison of a flow meter against a defined reference. The reference method and arrangement must be appropriate to the measurement system and required uncertainty.
Transfer-meter verification and calibration facilities use different proving systems. Flow range and the installed meter technology affect compatibility.
Compact provers, other displacement arrangements and master meters serve different setups. Specify reference method, connections and traceability requirements.
Tank gauging and overfill prevention
Tank gauging measures inventory-related conditions such as liquid level. Overfill prevention provides a separate protective function within the approved tank system. Measurement and protection should be identified as distinct duties.
Storage terminals and tank farms use these systems for operating information and specified protective functions. Product properties and tank geometry affect instrument selection.
Specify level technology, accuracy, alarm functions and system interfaces. Required independence and approvals follow the actual tank design.
Additive injection and blending systems
Additive-injection systems meter a secondary stream into a product, while blending systems combine streams to achieve a specified mixture. Pumps, measurement and controls work together within the process design.
Fuel terminals and process plants use these systems to achieve defined product requirements. Flow variation and component properties influence dosing and mixing duties.
Ratio range, accuracy, materials and sampling arrangements distinguish packages. Include control interfaces and the required package boundaries.
Loading rack grounding and shutdown systems
Loading-rack grounding and shutdown systems support specified bonding, permissive and protective functions during product transfer. Sensors, interlocks and controls form part of the approved loading-system design.
Truck and other terminal loading installations use these components with the facility's transfer equipment. Existing control interfaces determine compatibility.
Specify bonding verification, permissive logic and shutdown interfaces. Area classification, device approvals and installation responsibilities must be identified.
