Pipeline Gas Metering Station
The wide range of various organic and inorganic components makes it difficult to reliable determine natural gas qualitatively and quantitatively. There is a very exact definition of quality together with exact control in the international natural gas business to quarantee that delivery agreements are exactly observed.

Pipeline Gas Metering Station designed for simultaneous continous analysis the quality and quantity of natural gas being transferred in pipeline, as follows: •
Upper Calorific Value – CV, which is the latent energy content of a gas which is released during combustion. It is the major variable when defining the price
•
Concentration of Sulphur compounds. Hydrogen Sulphide and Mercaptans are partially present as natural compounds and sometimes they are mixed with the gas together with other Sulphur compounds as odorants
•
Hydrocarbon Dew Point is a temperature at which higher hydrocarbons condense. Liquid phase is produced in the gas pipeline if the hydrocarbon dew point is fallen below. The accumulation of liquid in the pipelines can lead to a plug flow and may destroy the compressors in the pumping station
•
Water Dew Point is the temperature at which water condenses out. Water together with hydrocarbons favors the generation of solids, in particular during the decompression of gas from high-pressure pipelines. The solids block gas fittings, and the water is corrosive.
•
Natural gas volume and mass flow, without additional pressure drop and pressure or temperature effects on fiscal measurement and calculation
The system consists of multi-path ultrasonic flowmeter, process gas chromatograph and computer workstation installed, prewired and prepiped in a special air-conditioned shelter with all auxiliary equipment and utilities.
