Metering performed by the set meet the requirements of GOST R 8.615-2005 for separate wellsites metering.

Proper use

Automated metering sets are meant for periodical crude oil and non-associated oil gas made from the oil and gas wellsites quantity metering by direct and indirect ways. The set is also used for the metering results further software processing for its storage, archiving and ensuring the results transmission to the telemetry system through the communication channels installed by the users.

The product components

Accordingly to the construction the set may enclose one to two liquid and gas flow metering devices of the following models:

  • F, CMF, T, R series MICRO MOTION mass volumeters, DN 15mm-150 mm;
  • PROMASS mass volumeters, DN 8 mm-250mm;
  • ROTAMASS mass volumeters of RCCS, RCCT, and RCCF modifications;
  • SFC mass volumeters;
  • MASSFLO mass volumeters.

Other models of mass volumeters are possible to use if they meet the following conditions:

  1. Certificate of measuring equipment type approval.
  2. Declared measuring range ensuring.
  3. Parameters measuring allowable relative error ensuring within the metering set according to the requirements of GOST R 8.615-2005.

Switching between wellsites in the sets is performed in one of the following ways:

  1. Using electrically actuated three way ball valves;
  2. Using multiway wellsites switch.

Production stream division to gas and liquid (oil water) is performed by gas-oil separators. Number of wellsites rigged in the set is from 1 to 14 pieces.
