Where product changes hands, the measurement is the invoice. We build the metering automation that both parties trust.
Custody transfer is the point where ownership of oil or gas changes. The quantity measured there is invoiced, so the measurement has to be accurate to international standards, continuous, and backed by an audit trail that survives a dispute. This is a different discipline from plant control, and it is one of our specialities.
A natural gas metering skid for ADNOC and AD Ports in Abu Dhabi with Nirmal Industrial Controls. Fuel transfer station metering for Camel Oil and Oilcom in Tanzania. A meter prover system for Inelgas Metering Systems. Multi-party custody transfer at the GAIL Vizag dispatch terminal.
The numbers on this screen are the invoice. The flow computer measures to international standards, the PLC moves the valves, and every proving run and total is recorded so both buyer and seller can trust it.
A 0.2 percent measurement error on a metering skid is worth more than the skid in a year. Regulators and counterparties expect fiscal-grade computers and a prover trail.
Three to five months including skid FAT; panels can be built in parallel with the skid.
Attach these to your enquiry. The three marked essential are enough for us to start a budget.
These size the meter runs and select the flow calculation we configure.
AGA, ISO or API calculations differ, and the clause sets the accuracy we must show.
Run count and prover type decide I/O, valve sequencing and proving screens.
Pulse, HART or Modbus outputs decide flow computer inputs and wiring.
Compressibility and density corrections need real composition, not assumed values.
It decides barriers, certified enclosures and cable entry.
Our panel work and your skid FAT have to line up, or the skid waits for us.
Multi-party custody transfer needs read access and reports agreed for each side.
They fix who attends proving runs and which certificates we must file.
Do not have all of it? Send what you have; we work from a site visit for the rest.
Overall: Three to five months including skid FAT; panels can be built in parallel with the skid.
Every plant is different, so we price from the I/O list and scope rather than a rate card. Send the documents above and you will have a budget figure within a week, and a fixed price after the scope call.
PLC, SCADA and flow computer integration for a fiscal gas metering skid, executed with Nirmal Industrial Controls.
Emerson FloBoss S600+ flow computers calculate flow to AGA, ISO, GPA and GERG; the GE PLC handles skid logic and valves; Cimplicity shows meter runs and totals. Panels built in Mumbai to our specification.
Metering automation for multi-product fuel receipt stations.
Per-line temperature, pressure and flow with meter totals for petrol, diesel and jet fuel, plus alarms, trends, reports and diagnostics.
An automated prover that verifies custody transfer meters read true.
The HMI routes flow through the prover, compares master meter and test meter volumes across repeat passes, sequences the valves and computes the meter factor.
A fiscal flow computer such as the S600+ computes custody transfer volumes to published standards with high-precision maths, secure configuration and audit trails. The PLC handles valves and skid logic; the flow computer owns the measurement.
That depends on the contract and the regulator, but a prover lets the operator check the meter factor on demand and keep a record of every proving run.
Complete plant control from one control room: tank farm, pumps, carousels, interlocks and OISD-214 data sharing with the pipeline.
Detection, deluge valve control, sequenced fire water pumps and jockey pump pressure management to OISD-144.
Dispatch and receipt terminals on redundant PLC and SCADA, so a single failure never stops the line.
Live tank levels posted to SAP every morning without manual entry, running at about 22 IOCL and BPCL plants.
