Research on Fully Automatic Flowmeter Cleaning Device

As a trade handover tool, the accuracy of flow meters directly affects factors such as customs clearance efficiency and enterprise cost accounting. It is necessary to regularly verify or calibrate the flow meter. However, during calibration, installing flowmeters with different residual media on the calibration device can cause pollution to the calibration medium of the calibration device. Rechecking the flow rate with contaminated media can also cause pollution to the tested flowmeters. Toxic and harmful media can cause secondary pollution with the use of the tested flowmeters, bringing incalculable secondary disasters. Although there are currently multiple methods for cleaning flow meters, each has its own advantages and disadvantages. Based on the characteristics of flow meter cleaning, this article conducts research on a fully automatic flow meter cleaning device. The device adopts advanced computer control technology, frequency conversion control technology, ultrasonic cleaning technology, sensor technology, medium environmental protection treatment technology, etc. The entire cleaning process is completely controlled by a computer, automatically completing the switching of cleaning media, adjusting the intensity of ultrasonic cleaning, starting and stopping the circulating pump, and adjusting the flow rate The adjustment of cleaning medium temperature and the determination of instrument cleanliness, while cleaning the instrument, the generated waste liquid is separated and reused, truly achieving full automation and pollution-free, solving the problems of narrow applicability, low cleaning efficiency, and easy environmental pollution of the current flow meter cleaning method. At the same time, the research and development of this device can serve the construction of oil and gas flow measurement capacity in the Zhejiang Free Trade Zone, ensuring the accuracy and reliability of key trade transactions such as industrial oil products and bonded fuel.
