Electromagnetic Flow Meters and Turbine Flow Meters: Operating Conditions and Performance

Abstract: Electromagnetic flow meter and turbine flow meter: operating conditions and performance information are provided by excellent flow meter and flow meter manufacturers. 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. 1. Electromagnetic flowmeter: Its indirect influence is the physical properties of the measured medium such as viscosity and density. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are electromagnetic flowmeters and turbine flowmeters: operating conditions and performance article details. 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. 1. Electromagnetic flowmeter: Its indirect effect is the change of physical parameters such as viscosity and density of the measured medium, but the indirect effect can be considered when correcting the physical effect. 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. 2. 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, whether it is turbocharged with exhaust gas is used. Whether it is a supercharger or a supercharger, the vortex flowmeter will encounter the problem of high intake air temperature. Because the compressed air temperature is definitely higher than that of the uncompressed vortex flowmeter. 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; for a 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. 3. 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 verification is also difficult to solve. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
