Terminal Metering
The meter skid where product changes hands between the terminal, the pipeline and the shipper, with a prover to check the meters.
What it does
Measures every barrel received or delivered for custody transfer. Coriolis or turbine meters do the measuring and a prover is run at intervals set by contract or company policy to confirm each meter factor.
Basics
| Meters | Coriolis or turbine |
| Check | Meter prover, meter factor |
| Proving frequency | By contract or company policy |
| Coriolis standard | API MPMS Chapter 5.6 |
Common failures
- Meter factor drifting between provings, so every transfer is off
Troubleshooting
- Symptom
- Meter factor changes between provings
- Likely cause
- Mechanical wear, installation effects or changed fluid properties
- What to check
- Prove again and inspect the meter and its piping
