Natural gas metering skid is a special assembly of valve, flow meter, piping and other instruments designed to accurately meter flow rate of natural gas in oilfield production facilities (early production facilities), gas processing plants and other gas receiving/transmission facilities.
Gas metering section are very important of any production, processing and storage facilities because it shows how much gas sold and/or purchased, thus, directly affects profit or gas-purchase expenses. For this reason, governments established special regulations for flow meters and structure of metering skids to ensure consistency of gas metering. Flow meters are the most important device of metering skid is they provide flow data to computer. There are several types of flow meters are available for gas metering, such as orifice plates, Coriolis flow meters, ultrasonic flow meter, turbine, and vortex flow meters. Ultrasonic flow meter is considered as most accurate for gas metering, while orifice plate and mass flow meters are also widely applied in gas industry.
