Differential pressure flow meter selection criteria

Abstract: Differential pressure flow meter selection standard information is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. Correct selection of measuring instruments Standard throttling devices should be preferred for measuring instruments. When the flow range is large, a wide range of intelligent differential changes should be considered. Other types of detection instruments should be carefully selected before the corresponding standards for measuring natural gas are introduced. Measurement of secondary instruments. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the selection criteria for differential pressure flowmeters. For the correct selection of measuring instruments, the standard throttling device should be the first choice. When the flow range is large, a wide range of intelligent differential change should be considered. Other types of detection instruments should be carefully selected before the corresponding standards for measuring natural gas are introduced. The measurement model of the secondary instrument should meet the requirements of SY/T6143-1996 to calculate the FL energy input components and calculate the c value in real time. 3.3 Strengthen technical training and learn from foreign experience. In practical application, the standard of 'Standard Orifice Measurement Method for Natural Gas Flow' (SY/T6143-1996) should be strengthened, and the 'Verification Regulations of Differential Pressure Flowmeter' should be strengthened for metrological verification personnel. (JJG640-1994), carry out training and learning activities within the oil field, hire oil field or domestic gas measurement experts to give lectures, in order to deepen the understanding of the standard and improve the technical level of verification and operators. Introduce, digest and absorb the new natural gas metering technology developed in recent years. From the perspective of foreign countries, energy measurement has almost completely replaced traditional volume measurement in natural gas international trade, while volume measurement still occupies a major position in the field of natural gas measurement in my country. In order to be in line with international standards as soon as possible, the user unit can jointly tackle key problems with various scientific research institutes, carry out the test work of natural gas energy measurement, and formulate standards on this basis for promotion and application. In order to speed up the test progress, it is recommended to introduce foreign advanced on-line gas chromatography systems and flow computers, and develop a natural gas energy metering system suitable for the actual production of oil fields on the basis of digesting the imported technology. **The annual output of natural gas in the oilfield is about 800 million m3, of which 400 million m3 is used for export. Natural gas has become an important economic resource of the oilfield. Natural gas flow measurement is an important technical basic work carried out on a daily basis in oilfield production and operation management. Accurate measurement of natural gas can not only make trade settlement fair, but also improve production technology, improve product quality, reduce product production costs, ensure safe production, and improve economic and social benefits. Oilfields currently mainly use differential pressure flowmeters in natural gas measurement. In the differential pressure flowmeter, the standard orifice throttling device is the most widely used because of its simple structure, low manufacturing cost, and standardization. At present, the throttling device of the differential pressure flowmeter in the oil field generally adopts the standard orifice plate. The above is the whole content of this article.
