When natural gas is exchanged between parties, accuracy is prominent either for custody transfer or system performance monitoring. Accordingly, the flow rate of the gas has to be measured, since payment is a function of the amount of gas transferred. A metering station includes equipment to filter and meter natural gas in two or more streams. Measurement devices, depending on the gas capacity and accuracy importance, may be turbine or ultrasonic meter types. Based on project specification and client’s order, installation can be either flat and cabinet type.
