A multiphase flow meter is a device used to measure the individual phase flow rates of constituent phases in a given flow (for example in oil and gas industry) where oil, water and gas mixtures are initially co-mingled together during the oil production processes.
Oil, gas and petrochemical processes are undertaken at specific temperatures. Measurement of temperature of fluids in the petrochemical industry is undertaken by temperature elements (TE). These can be Thermocouples or Platinum Resistance Temperature Detectors (RTDs). The latter are used for their good temperature response.
Sonar flowmeters have the capacity of measuring the velocity of liquids or gases non-intrusively within the pipe and then leverage this velocity measurement into a flow rate by using the cross-sectional area of the pipe and the line pressure and temperature. The principle behind this flow measurement is the use of underwater acoustics.
V-Cone Flow meter with raised face weld neck flanges. Flow meters for the measurements in the oil and gas upstream industry are chosen based on type of measurement, performance and accuracy requirements, and the type of medium to be measured. Available meters in the market are characterized by properties such as accuracy, operational ...
Simplified process flow diagram. A plant is receiving a multi phased flow of oil and gas from many wells via a manifold. Flow from one well only may be taken to the test separator (shaded). The test separator has the feature to separate gas and water from the oil, and to have each component measured, under different conditions.
Examples are gas-oil-water flows in oil recovery systems and immiscible condensate-vapor flows in steam/hydrocarbon condensing systems. [20] Further examples lie in the flow of oil, water and natural gas. These flow can occur in condensation or evaporation of liquid mixtures (e.g. the condensation or evaporation of steam or hydrocarbons) [9]
