Item Thermal flow sensor used for thermal mass flowmeter(Elsevier, 2020) Bekraoui, Amina; Hadjadj, AhmedActually, many devices used for flow rate measurement in oil and gas fiscal metering like orifice and turbine meters are often employed. This work deals with dispersion thermal flow meter fabricated by hot wire anemometers technology using the thermal domain for measuring natural gas in transaction operations, where it is unusually used. The choice of this type of flow meters comes from the fact that the authors observed an abnormality in the production field in the south of Algeria. Which consists of the total flow rate of different wells is extensively different from the amount recovered in the storage bin especially in the summer season. We are sure that the use of this kind of device will help us to understand this irregularity. The main objective of our work is to study the essential component of the thermal mass flow meter “thermal anemometer”, and to simulate this one with the parameters of Algerian gas field in order to have the ability to compare the results obtained with the field data. Attention is paid to the sensors’ geometry. Thermal anemometer flows sensor may comprise a heater and several temperature sensors. They convert the flow energy overheat transfer into electrical signalsItem An overview of thermal mass flowmeters applicability in oil and gas industry(Elsevier, 2017) Bekraoui, Amina; Hadjadj, AhmedItem An overview of thermal mass flowmeters applicability in oil and gas industry(Elsevier, 2017) Bekraoui, Amina; Hadjadj, AhmedMeasuring and modeling flow has played a central role in predicting its behavior and its effects on the surroundings. Flow measurement is the basis of trade between producers, transporters, process plants, state and public marketers. To improve transactional operation, thermal flowmeters could provide direct mass flow measurement of gases and vapors over a wide range of process conditions without the need for density corrections based on pressure and temperature. The flow meters are classified according to the domain in which they are used and their operating principle. The goal of this work is to provide an overview of using thermal flow meter in hydrocarbons industries. The applicability of thermal flow meters is discussed by a simulation using one-dimensional mathematical model of thermal flow sensor
