Regulator & Meter Station
A station where gas leaves a transmission line: it is measured, and its pressure is reduced for the next system.
What it does
Meters the volume handed over for billing and drops the pressure with regulators to what the downstream system can take, with overpressure protection in case a regulator fails.
Basics
| Does | Metering and pressure reduction |
| Protection | Overpressure protection downstream |
| Typical place | Transmission to distribution handover |
Common failures
- Regulator that fails open and overpressures the downstream system
Troubleshooting
- Symptom
- Downstream pressure creeps above set point
- Likely cause
- Regulator not holding or set point drifted
- What to check
- Switch to the standby run, check the overpressure protection and service the regulator
