Aiming at the problems of huge exhaust noise and air bubbles caused by sewage blowing-off at an inappropriate time for a submarine ST, a sewage level detection system is designed, which can detect in real-time the sewage level using a weighing sensor to achieve quantitative sewage blowing-off. Therefore, the theoretical analysis of the sewage blowing-off is carried out, and the process of the sewage blowing-off is simulated by a VOF model of Fluent. From the simulation, the gas-liquid volume distribution diagram, the volume curve of the sewage, and the flow rate curve of the outlet sewage are obtained. Furthermore, the installation and detection method of the weighing sensor are described in detail. Finally, an experimental test system for simulating the sewage blowing-off is established, and an ultrasonic liquid level sensor, capacitance level sensor, and weighing sensor are tested. By comparing the effects of the three sensors, the result shows that the weighing sensor is the most effective for real-time sewage level detection during the process of sewage blowing-off and can effectively reduce the exhaust noise of the sewage blowing-off system.
