Flow · Measurement
Coriolis Meter
A meter with vibrating tubes that measures mass flow directly, plus density and temperature.
What it does
Measures oil and condensate leaving the separator. The density reading is used to estimate water cut and net oil. No straight runs are needed.
Basics
| Measures | Mass flow, density, temperature |
| Liquid standard | API MPMS Chapter 5.6 |
| Gas standard | AGA Report No. 11 |
| Weak point | Free gas in the liquid |
Common failures
- Gas breaking out in the meter, readings scatter
- Meter mounted so tubes trap gas or settle solids
Troubleshooting
- Symptom
- Density and flow jump around
- Likely cause
- Entrained gas
- What to check
- Keep back pressure on the meter, check separator level and dump valve
