Oil & Gas Flow Measurement | Application Guide
Oil, gas and chemical injection. A practical application brief for defining a flow measurement system.
Define the duty
Define the fluid phase and composition, normal and extreme pressure and temperature, minimum and maximum flow, and whether the task is process trending, allocation or custody transfer. Produced water, fuel gas and liquid hydrocarbons require different selections.
Technology candidates
Coriolis is a candidate for mass measurement of liquid products and chemical injection. Ultrasonic systems may suit larger gas lines; turbine meters may suit clean, stable, low-viscosity products. Evaluate the specific model, operating range and installation rather than selecting by principle alone.
Installation and selection checks
Check pressure rating, wetted materials, hazardous-area requirements and available straight runs. For a commercial transfer, agree the complete measurement system: compensation, proving or calibration, records and applicable approval requirements. A suitable process meter does not automatically qualify for custody transfer.
Commissioning and ongoing use
At commissioning, confirm units, compensation settings, pulse scaling and totaliser rollover. Compare readings against an agreed reference under representative operating conditions. Keep the acceptance method and calibration evidence with the asset record.
What to send with your enquiry
Include the fluid and its properties; minimum, normal and maximum flow; pressure and temperature; pipe internal diameter, material and lining; connection requirements; available installation space; power supply; and the required pulse, analogue or digital interface.
State the decision the measurement must support, the required accuracy across the operating range, and any calibration, certification or reporting documents. Supply a marked-up pipe sketch and identify access or shutdown constraints so the quotation can cover installation and integration as well as the meter.
Sensor and equipment options
Browse these live products as selection candidates. Confirm the exact model and configuration against your application; listed ranges and options are not interchangeable.
Mass measurement candidate for compatible liquid duties; confirm the exact operating range, pressure loss and materials.
Candidate for the specified clean-gas duty. Confirm composition, pressure, temperature and compensation configuration.
Candidate for compatible viscous oil transfer. Check viscosity, filtration and pressure drop.
Separate process monitoring from trade measurement. None of these links establishes hazardous-area, custody-transfer or billing approval. Obtain the required certificates for the exact supplied assembly before selection.
Build the complete measurement system
Process connection → selected meter or sensor → compatible signal input → local indication, totalisation or recording → optional telemetry and monitoring → agreed operator response.
Pulse: confirm pulses per litre or the required K-factor and receiving input frequency. 4–20 mA: agree the range, units, wiring and fault interpretation. RS485/Modbus: verify the exact register map, address, serial settings, scaling and byte order. A matching connector is not evidence of compatibility.
Keep flow rate and accumulated volume separate. Logging a 4–20 mA flow signal does not automatically provide reliable totalisation; specify and verify that calculation or read the meter's own cumulative total. Remote communications and cloud dashboards need an agreed device and integration path.
What the quotation should include
Exact meter model and size; wetted parts and seals; process fittings; transmitter and output configuration; power supply; indicator or logger; mounting and enclosure; cables; calibration documents; software and communications; and any requested configuration, installation or commissioning. Hardware listings include only their stated components and selected options.
