The effect of operating conditions and environment on the performance of flow meters

Abstract: Information on the influence of operating conditions and environment on the performance of flow meters is provided by excellent flow meter and flow meter manufacturers. When many customers buy flow meters, they often have questions about a series of questions from flow meter manufacturers, why do they ask about working pressure, working temperature, working environment and so on. Are these relevant to buying a flow meter? The operating conditions of the flow meter. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the details of the article on the performance of flowmeters affected by operating conditions and environments. When many customers buy flow meters, they often have questions about a series of questions from flow meter manufacturers, why do they ask about working pressure, working temperature, working environment and so on. Are these relevant to buying a flow meter? The operating conditions or operating conditions of a flow meter directly affect its measurement performance. The most direct impact of operating pressure or temperature changes on a flow meter is the change of its metering cavity. Chengfeng turbine flowmeter: For volumetric flowmeters, after the naturally aspirated engine is converted into a supercharged engine during the type identification, prototype test or quality inspection of the flowmeter, no matter whether the exhaust gas turbocharger is used Whether it is a supercharger or a supercharger, the vortex flowmeter will encounter the problem of high intake air temperature. Chengfeng electromagnetic flowmeter: Its indirect influence is the change of physical parameters such as viscosity and density of the measured medium, but the indirect influence can be considered when correcting the physical property influence. Due to the complexity of the structure and shape of the flow meter and the discreteness of its processing and assembly, it is almost impossible to use the calculation method to accurately correct the change of its cavity with the operating conditions, and it is also impossible to fit all flow meters according to the test data. Empirical formula for meeting accuracy requirements. Chengfeng vortex flowmeter: Because the temperature of compressed air is definitely higher than that of uncompressed air. The intake air temperature of a naturally aspirated engine does not change greatly regardless of the state of the engine, whether it is installed in the air flow meter, or on the intake manifold or air box not far from the throttle valve, it is all different. Not much; Velocity turbine flowmeter: Changes in operating conditions will cause changes in its flow area, resulting in changes in meter coefficients. If the operating conditions of the flow meter during verification can be the same or close to those in actual use, offline verification can meet the requirements. However, due to the complexity and variability of operating conditions, offline verification often cannot reproduce actual operating conditions. Only online real-flow verification can solve the problem of high-accuracy flow measurement, otherwise additional errors must be considered. In a broad sense, the flow conditions such as the uniformity, gas (liquid) content, and impurity content of the measured medium also belong to the category of flowmeter operating conditions, but their impact on the performance of flowmeters is more complicated, and sometimes online real flow Checks are also difficult to solve. I hope that after reading this article, you can understand why customers ask these questions, because these factors will affect the performance and accuracy of customers when they use them. If he doesn't ask anything, it's a breach of duty. Hope everyone can buy the right flow meter! There are a wide variety of flowmeters, complete styles, factory direct sales, quality assurance, and affordable prices. Customers are welcome to come to consult and buy. Help with selection and solve your flowmeter questions. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
