Automated Metering Unit (AMU)
Measurement providing by this station meets the requirements for independent wells measurement.
Automated Metering Unit: Application
Automated Metering Stations are designed for periodical direct and indirect measurement of the quantity of raw oil and free casing head gas being produced from oil and gas wells and further hard- and software processing of the results in order to collect, archive and transfer them to the telemetry system through communication channels to the specified users.
AMU:
Depending on a model AMU can be equipped by one to two devices for liquid and gas flow metering:
- MICRO MOTION mass flow meters, series F, CMF, T, R DN 15mm – 150mm;
- PROMASS mass flow meters DN 8mm – 250mm;
- ROTAMASS mass flow meters, series RCCS, RCCT, RCCF;
- SFC mass flow meters;
- MASSFLO mass flowmeters.
It is allowed to use other models of mass flow meters that must comply with the following conditions:
- Certificate of conformity for measuring equipment type.
- Conformity of the declared measurement range.
- Conformity of allowable relative measurement error of parameters.
- Three-way ball valves with electric actuators;
- Multi-stream switching manifold (MSM).
Gas and liquid separation (oil + water) received from wells is provided by oil and gas separators. The number of wells that can be connected to this unit is from 1 to 14 pcs.
