Liquid flow measurement in large-diameter pipelines Features of liquid flow measurement in large-diameter pipelines ①The larger the diameter of the pipeline, the smaller the pressure loss, the better. It is generally not allowed to increase the flow rate by local diameter reduction. ②The flow rate is generally not high. For newly designed and installed pipelines, economic flow rates are generally selected. Because the flow rate is too low, it is bound to increase the investment in pipelines, and the flow rate is too high, which will cause a substantial increase in power loss and lead to an increase in operating costs, which is uneconomical. For some old pipelines, the flow rate has been increased due to the need to increase production. ③Due to the low flow rate, dirt and silt in the fluid are easily deposited on the inner wall of the pipeline. When designing the operating system, the cleaning of the parts in contact with the instrument and the fluid should be considered. ④ The measurement range is required to be large. The flow rate of some water pipes varies greatly between nighttime and daytime, winter and summer, as many as 10〜20 times, some air conditioners simply stop using water in a certain season. Therefore, the flow meters for these waters require a particularly large range. ⑤ High protection level requirements. Most of the large-diameter pipelines are laid underground in order to save space. In the north, it is also necessary for anti-freezing. Therefore, the flow sensor is mostly installed on the pipe section in the instrument well. Rainwater, well wall leakage and pipeline leakage often cause the water level in the well to rise and flood the flow sensor, so this situation should be considered during design.
