This article focuses on the CUQ-1 type oil tank pneumatic telemetry and alarm system design ideas, test results and the use of results. Emphasis on: 1. Bubble method of measuring the dynamic process principle, pointed out the main factors affecting the accuracy. 2. Block the characteristics of constant current control system and the bubbler. 3. Measurement of air flow and air pressure to determine. 4. To reduce the error signal transmission methods and piping layout. 5. Reduce the design of indicator error and indicator. 6 safety and inflatable device structure. 7. Simplify operation and dual control rotary valve structure. 8. Calculate the maximum tracking speed of the measurement system based on the formula proposed by the author. Pneumatic full emptying and emptying alarm system. 10. Piping and fittings. In this paper, CUQ-1 system real ship experimental results and test curves are introduced to prove that the principle is feasible, accurate measurement, fast tracking, good repeatability, small air flow, and to determine the effect of pipe length on flow resistance and the value of Changes in the measurement process. Finally, the advantages of the CUQ-1 system are described. A comparison of the main characteristics of each typical system is given.
