Is there a difference between the v-cone flow meter sample and the actual product?

Project Overview

V cone flowmeter is a commonly used flowmeter. It has the advantages of high precision, high stability, and high repeatability. It is widely used in petroleum, chemical industry, natural gas and other fields. When we purchase a flow meter, the parameters we can see such as accuracy level, stability, repeatability, etc. are basically sample data. In actual use, many users will find that the actual product is different from what is advertised in the product brochure. Why is this? Some parameter values ​​in the brochure are obtained from samples. The manufacturer measures the samples according to national standards and industry specifications. These parameters include flow range, accuracy level, material, etc. Generally speaking, the parameters on the samples have been rigorously tested and verified and have high credibility.

However, the actual product may differ from the parameters in the sample due to errors in the production process, differences in installation conditions, changes in the use environment and other factors. For example, errors in the production process may cause the measurement accuracy of the actual product to be inconsistent with the sample; differences in installation conditions may affect the accuracy of the flow meter; changes in the use environment may affect the stability of the flow meter. To sum up, although the parameters on the sample have a certain degree of credibility, the actual product may differ from the sample due to various factors.
