ultrasonic level meter led display ultrasonic sensor non-contact level measurement device 10m range 24v power 4-20ma output

since the transmitted ultrasonic pulse has a certain width, the reflected wave and the transmitted wave in a small region closer to the transducer overlap, and cannot be recognized, and the distance value cannot be measured. this area is called the measurement dead zone. the size of the blind spot is related to the model of the ultrasonic level gauge.
