Things to note when using Anubaa flow meters

Thread Content

　　When selecting a flow measurement instrument, it is necessary to rely not only on theoretical knowledge but also to analyze the process conditions and properties of the medium, taking into account the issues that need attention when using Anubaa flow meters, in order to choose an instrument suitable for those conditions. Since the integrated Anuba flow meter was installed and put into operation over a year ago, the accuracy of gas measurement has improved significantly, resulting in good economic benefits. This demonstrates its reliability in measuring gas with high impurity content. Below, we will discuss together the issues that need to be taken into consideration when using the Anuba flow meter. 　　(1) The mechanical dimensions of the Anubaa flow meter must be customized according to the size of the pipeline in which it is to be installed. The parameters provided by the user must include details such as the outer diameter of the pipeline, wall thickness, and typical flow rates. During the manufacturing process of Anubaa, the calibration of the flow measurement range is carried out entirely based on the data provided by the user. Therefore, providing flow data and pipe sizes based on experience and impressions will result in significant measurement errors. 　　(2) The differential pressure signal generated by a differential pressure type venturi flow meter is generally quite small, with a minimum of only 20–30 Pa. The magnitude of this differential pressure signal is closely related to the Reynolds number of the fluid under operation. Diff pressure measurements below 1 kPa, especially those below 0.5 kPa, place a significant strain on the performance of transmitters. For various constant-velocity tube flowmeters, the variation in K under such low flow rates is very large, affecting the measurement accuracy. 　　(3) After the differential pressure signal is acquired, try to avoid using pressure lead pipes in order to improve the signal-to-noise ratio of the differential pressure signal and reduce leaks. We adopted a direct installation method that integrates Anubaa, the three-valve assembly, and the differential pressure transmitter, completely eliminating components such as pressure lead pipes, drain valves, and mounting brackets. In this way, not only are issues such as leaks caused by the use of pressure transfer pipes and distortion of differential pressure signals reduced, but costs are also lowered and accuracy is improved. 　　The above is a summary of the points to keep in mind when using Aniuoba flow meters. The author is offering these insights as a starting point; if anyone has better suggestions, please feel free to leave comments for discussion, so that we can all improve together.
