Abstract: the precession vortex gas meter scale applications and attention to use information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Precession vortex gas flowmeter in the process of production and storage and transportation of crude oil, a speed meter, which has been widely applied because of its no moving parts, with temperature and pressure correction function, at the scene of the harsh conditions to measure the gas flow standard value,. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the precession vortex gas meter scale applications and attention to use the article for details. Precession vortex gas flowmeter in the process of production and storage and transportation of crude oil, a speed meter, which has been widely applied because of its no moving parts, a correction function, temperature and pressure at the scene of the harsh conditions to measure the gas flow standard value, with high cost performance, can meet the requirements of enterprise production and operation management. In the petroleum, petrochemical system at present, the flowmeter is mainly the following situations: ( 1) Used for the associated gas in the process of production of crude oil metering, mainly installed on the upper part of the oil separator gas exports, after separation of natural gas after measurement, and mixed with gathering line, to transfer station. Because of the associated gas contains a certain amount of light hydrocarbon, carbon dioxide, water and other medium, as the change of temperature, pressure, the saturated state of the above group branch out of a condensate gas, the content & lt; 15%, the accuracy of measuring & le; ± 5%, therefore, the application of the flowmeter at the scene of the crude oil production is more, accounting for 95% of the gas meter. ( 2) Used for crude oil transfer, gathering station after dealing with the oil and gas water three phase separator, gas storage and transportation. In the natural gas light hydrocarbon, carbon dioxide, water and other media content & lt; 5% of cases, the accuracy of measuring & le; ± 3%. ( 3) Used in production of crude oil gathering station library with boiler, hot water heater energy facilities such as consumption of natural gas measurement, after the heating facilities to produce steam and hot water, as a carrier can working medium used in the oil storage and transportation in thermal insulation. Because of natural gas is relatively pure, accuracy of measuring & le; ± 2%. Due to the precession vortex flowmeter is a kind of speed meter, the flow through the throttle fault accelerates a vortex flow, will produce the pressure loss, therefore, should try to avoid the problems in use: ( 1) Good guarantee for a single Newton body measurement, if crude and trace impurity particles is more, should be before the flow separation, filter, otherwise it will cause the measured value is greater than the actual value. ( 2) The selection of flow meter should be according to the actual flow medium, rather than the diameter of the pipeline installation, it is very important. ( 3) To avoid ranges of pressure sensor, and measuring errors caused by temperature, pressure sensor error, the current use of intelligent vortex precession flowmeter pressure sensor range is 2. 0 mpa, the actual range in gas pressure & le; ± 0. 3 mpa, can make the standard state of natural gas measurement error increases. At the same time, as a result of the oil field using intelligent precession vortex flowmeter, most used in non-trade metering transition, flow meter to check, cause stress, temperature sensor to produce zero drift, can cause gas sent error increases, so must be verification was carried out on the schedule of flowmeter in proofreading. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
