RG-ONT gas flow meters (hereinafter referred to as gas meters) measure flow by the differential pressure method and are built on the basis of averaging Pitot tube. The design of the gas meters is made in a single block manner intended for installation directly on the pipeline.

This gas meters are intended for:

• measuring of the time and duration of pauses in flow and volume measuring;

• measuring of the absolute pressure and the temperature of a fluid flowing through a measuring pipeline;

• measuring of the flow rate and volume of air or natural gas (hereinafter referred to as gas) or technological measurement with an unspecified error of the flow rate and volume of gas phase of a product of gas- or gas condensate wells at measurement conditions and converted to base conditions, that flows through one pipeline in the forward and reverse directions;

• formation of measurement results-, operator interventions- and emergency messages archives and their representation at the indicating device, as well as transfer of archive information to the automated system.

NOTE  Technological measurements of the flow rate and volume of gas phase of the product of gas- and gas condensate wells and error estimation of such measurements are carried out according to specially developed procedures, the application and testing of which is a subject of agreement between the product supplier and the consumer.
