[China Instrument Network Instrument R&D] Recently, four scientific research projects of the National Steam Flowmeter Product Quality Supervision and Inspection Center passed acceptance, including one AQSIQ science and technology project and three science and technology projects of the Fujian Provincial Quality Supervision Bureau.


The new stagnation container developed by the AQSIQ Scientific Research Project “Research on a vibration-reducing stagnation vessel with temperature regulation function” adopts an internal and external double-layer structure to form a cooling water circulation system in the walls of the two-layer vessel to achieve effective temperature control. And regulation; stagnation containers increase the water ring damping system, with good damping effect. Experts in the acceptance group believe that the research results have reached the leading domestic level.

In the science and technology project of Fujian Provincial Bureau of Quality Supervision, the pipeline vibration suppression device developed by "Research on the Effect of Pipeline Vibration on the Metering Performance of the Flowmeter and Vibration Reduction Method" effectively reduces the influence of pipeline vibration on the metering performance of the flowmeter; Detection and Tracking of Wireless Video Security Monitoring and Alarming Devices ” A set of intelligent video security monitoring and alarm devices integrating digital video processing technology, automatic control, wireless network transmission, and artificial intelligence, which can realize real-time detection and tracking movement into the monitoring range The target can be automatically alarmed and stored, and has strong anti-environmental interference and broad application prospects. The open channel flow meter and its test device based on laser measurement technology developed by “Open Channel Flowmeter Based on Laser Measurement Technology” adopt laser, ultrasonic and electromagnetic induction. The combination of measurement techniques enables a multi-parameter measurement of open channel flow to achieve a transition from theoretical to actual measurement of fluid flow in open channels. Experts in the acceptance group believe that the above three research results have reached the domestic advanced level.
