When many customers purchase flow meters, they often question the flow meter manufacturers' series of questions. Why do they have to ask the pressure of work, the working temperature, the working environment, and so on? Are these related to buying a flow meter?
The operating conditions or operating conditions of the flow meter directly affect the metering performance. The most direct influence of the operating pressure or temperature change on the flow meter is the change of the metering cavity.
Chengfeng Turbine Flowmeter: For volumetric flowmeters, when performing flow rate meter type identification, prototype testing, or quality inspection, the naturally aspirated engine is converted to a supercharged engine, regardless of whether turbocharger is used. Or the supercharger, vortex flowmeter will encounter the problem of high intake air temperature.
Chengfeng electromagnetic flowmeter: Its indirect influence is the change of physical properties such as viscosity, density, etc. of measured medium, but the indirect influence can be considered when correcting the influence of physical properties. Due to the complexity of the structure and shape of the flow meter and the discreteness of processing and assembly, it is almost impossible to use a calculation method to accurately correct the cavity with the change of operating conditions, and it is impossible to fit all the flow meters according to the test data. Experience formula to meet accuracy requirements.
Chengfeng vortex flowmeter: Because the compressed air temperature is definitely higher than the uncompressed one. The intake air temperature of naturally aspirated engines does not change much under any conditions. Whether it is installed in an air flow meter or on the intake manifold or the wind box, which is not far from the throttle valve, there is a difference between them. Not great
Velocity turbine flowmeters: Changes in operating conditions will cause changes in their flow area, resulting in changes in the meter factor. If the operating condition of the flow meter is checked to be the same as or close to the actual use, the offline verification can meet the requirements. However, due to the complexity and variability of operating conditions, off-line verification often fails to reproduce actual operating conditions. Only on-line real-flow verification can solve high-accuracy flow measurement problems. Otherwise, additional errors should be considered.
In a broad sense, the flow conditions of measured medium uniformity, gas (liquid) content, and impurity content also belong to the category of flowmeter operating conditions, but their influence on the performance of flowmeters is even more complicated. Tests are also difficult to solve.
I hope that everyone read this article to understand why the customer has to ask these questions, because these factors will affect the performance and accuracy of the customers when they use the products. The manufacturers hold the attitude of thinking for the customers and must consult similar issues. If he does not ask anything, this is a default. I hope everyone can buy the right flow meter!
