JM200 ultrasonic level gauge

Measurement principle: The ultrasonic level meter emits high-frequency ultrasonic pulses from a transducer (probe) and is reflected back when encountering the surface of the measured medium. Part of the reflected echoes are received by the same transducer and converted into electrical signals. Ultrasonic pulses propagate at the speed of sound waves, and the time interval required from emission to reception of ultrasonic pulses is proportional to the distance from the transducer to the surface of the measured medium. The relationship between this distance value S, sound speed C, and transmission time T can be expressed by the formula: S=CxT/2. Due to the certain width of the emitted ultrasonic pulse, the reflected and emitted waves in a small area close to the transducer overlap, making it difficult to identify and measure their distance values. This area is called the measurement blind spot. The size of the blind spot is related to the model of the ultrasonic level meter.

Detailed introduction

JM200 ultrasonic level gauge

Measuring principle
The ultrasonic level meter emits high-frequency ultrasonic pulses from a transducer (probe) and is reflected back when it encounters the surface of the measured medium. Some of the reflected echoes are received by the same transducer and converted into electrical signals. Ultrasonic pulses propagate at the speed of sound waves, and the time interval required from emission to reception of ultrasonic pulses is proportional to the distance from the transducer to the surface of the measured medium. The relationship between this distance value S, sound speed C, and transmission time T can be expressed by the formula: S=CxT/2. Due to the certain width of the emitted ultrasonic pulse, the reflected and emitted waves in a small area close to the transducer overlap, making it difficult to identify and measure their distance values. This area is called the measurement blind spot. The size of the blind spot is related to the model of the ultrasonic level meter.
