Selection of flow meter
2011-12-1 8:11:42

使用寿命和准确性,选型时还要注意仪表的防振要求,在湿热地区要选择湿热式仪表。 In order to ensure the service life and accuracy of the flowmeter , pay attention to the anti-vibration requirements of the meter when selecting the model, and choose a wet-heat meter in the hot and humid area.

Correctly selecting the specifications of the instrument is also an important part to ensure the life and accuracy of the instrument. Special attention should be paid to the selection of static pressure and high temperature resistance. The static pressure of the instrument is the degree of pressure resistance. It should be slightly greater than the working pressure of the measured medium, which is generally 1.25 times to ensure that no leakage occurs.

Or accident. The choice of the measuring range is mainly the choice of the upper limit of the meter scale. If you choose a small one, it is easy to overload, and the meter will be damaged; if you choose a large one, it will hinder the accuracy of the measurement. Generally selected as 1.2-1.3 times the maximum flow value in actual operation.


For long-term contact meters installed on production pipelines, the energy loss caused by flow measurement elements should also be considered. In general, multiple measuring elements with large pressure loss, such as throttling elements, should not be selected in the same production pipeline.


对各种流体及流动情况都能适应的。 In short, no measurement method or flow meter can adapt to various fluids and flow conditions. Different measurement methods and structures require different measurement operations, methods of use, and conditions. Each form has its own unique advantages and disadvantages. Therefore, the

Way and.

Based on a comprehensive comparison of instrument characteristics, the best type that is suitable for production requirements, is safe, reliable, and economical and durable.
