OZNA-Engineering that has many years of experience in Process Control Systems and Fiscal Metering Systems offers a OZNA-Global complex – which is a complex of measures in design and implementation of various Process Control Systems into industrial operation.

OZNA-Global is a ready solution for oil production, oil metering, telemechanics and control of energy resource of industrial companies, and makes up a complex of hardware and software comprising of the following:

  1. OZNA-Flow Data Processing System for Fiscal Oil, Gas, Water Metering Systems
  2. OZNA-Geo telemechanics system for remote facilities
  3. OZNA-Energy a system for energy metering

The main criteria for Control System are the possibility for further expansion. All changes of the operated facility are made in rather short term and without considerable labor cost.

Control Solutions supplied by OZNA-Engineering meet all requirement of customers in flexibility, expansion capability, reliability and have no limits on implementation in the oil and gas industry. This is good for Fiscal Metering and for Process Control Systems of Modular Equipment (like Water Injection Stations, Metering skids, Chemical Injection Packages) and field facilities. OZNA Control Systems have been implemented in such large companies like Transneft, Rosneft, Surgutneftegas, Pechoraneft.

Main stages of Process Control System implementation

  1. Design of project and metrological documentation:
    • Pre-design inspection of an object to be automated
    • Draw up and agreement of Specification
