Gas flow meter3/10/2024 The more fluid that passes around it, the faster it cools, indicating greater flow volumes. This meter measures the fluid volume based on the heat transfer or temperature change, from a heated element positioned in the flow stream. They are also expensive, so they are not suitable for large flow volumes because larger meters are not cost effective to produce.Īnother type of mass flow meter is a thermal mass flow meter. Voltage is generated by vibrations, sine waves are created, and the time delay in motion is proportional to the mass flow rate.Ĭoriolis meters are extremely accurate. Using motion mechanics, it splits the process fluid into two tubes oscillating in opposite directions. The Coriolis meter is the most common mass flow meter used in the oil and gas industry. A mass flow meter measures this rate and is dependent on the density and velocity of the liquid and the size of the meter. The mass flow rate is the amount of liquid that passes through a meter over a given unit of time. The first one we’ll talk about is a mass flow meter. In the midstream, they can be used for inventory measurement, process control, fuel management and regulatory reporting. In upstream production, they can be used to monitor individual well production, custody transfer at a sales meter or to meter the amount of chemicals being injected. Each meter measures the flow rate, but the operation and methods of measuring are different.Įach one of these meters can be used in both upstream production and midstream transportation. ![]() ![]() ![]() Producers use several types of flow meters depending on their gas volume and fluid properties. These meters may be on a separation vessel monitoring production volumes, or they are used for custody transfer, where the gas is measured, and a midstream company takes ownership of it. After natural gas is produced from a well and initial separation has taken place, it will travel through a gas flow meter to measure the production.
