What are the precautions during the installation of plug-in ultrasonic sensors?

1. Pay attention to positioning on the measuring pipe (surface treatment of the pipeline, ensuring that the positioning points of the two ultrasonic sensors pass through the centerline and form a straight line)The base is firmly welded and sealed vertically, the ball valve is sealed without leakage, and the opening ensures that the tool is drilled at a normal and uniform speed;
2. Attention for the installation of ultrasonic sensors (when installing ultrasonic sensors, people should stand on the slope of the sensor and hold it with their hands to prevent excessive water pressure from injuring people or damaging the ultrasonic sensor chip and guide rod. The installation must be relatively parallel to the pipeline at the same time);
3. Insertion depth of ultrasonic sensor (referring to a total length of 270mm from the top of the ultrasonic sensor to the inner side of the guide rod, which must be subtracted from the pipeline wall thickness and lining during installation).
