摘要

In the industry, liquid leakage can occur during accidental events. When liquids leak out of the container or reactor, they can harm creatures, humans, and the environment. A measurement technique that can visualize the leakage location within a reasonable budget is therefore required. This paper proposes a low-cost ultrasonic measurement to estimate the leakage point in the container or reactor. The measurement system utilizes only a single ultrasonic transducer and compact pulser/receiver. The basic ultrasonic velocity profiler (UVP) is used as the measurement algorithm. The concept operates with a small angle rotation on the measurement line. The velocity vector profile is then reconstructed, and the leakage point is estimated. The experimental demonstration was conducted in a rectangular water tank to simulate the leakage location. The measurement result was found to be reasonable, meaning the leakage location can be estimated from the vector profile obtained.
