The larger the calibre of the V-cone flowmeter, the less accurate it is?

Project Overview

　　The accuracy of V cone flowmeter does not directly depend on the size of its calibre.V cone flowmeter is a kind of differential pressure flow measurement instrument, it is installed in the pipeline through a special V-shaped cone to generate differential pressure, so as to achieve the measurement of fluid flow. Factors affecting the accuracy of V cone flow meter mainly include:

　　Fluid conditions: Changes in physical properties including temperature, pressure, viscosity of the fluid may affect the measurement accuracy.

　　Installation conditions: such as straight pipe section requirements are met, whether there are impurities or foreign objects in the pipeline will affect the accuracy of the measurement results.

　　Manufacturing quality: V cone design, processing accuracy and material selection will also affect the performance of the flowmeter.

　　Use of the environment: external environment such as vibration, electromagnetic interference and other factors may also have an impact on the measurement.

　　Maintenance status: after long-term use, if there is no regular calibration and maintenance, may lead to increased measurement error.

　　For different calibres of V cone flowmeter, the manufacturer will usually according to the specific calibre and application to design the most optimal structural parameters, to ensure that in different flow ranges can achieve a high degree of measurement accuracy. Therefore, it can not be simply said that the larger the calibre the lower the accuracy. In fact, in the appropriate conditions of use, large calibre V cone flowmeter can also maintain good measurement accuracy. When choosing a suitable flowmeter, the above factors should be considered to ensure that the selection is correct and meet the actual needs.
