Installation Notes 

 Henan SIA instrument warm ultrasonic level meter to remind you there is near blind, in order to avoid the measured medium plane into the level meter of the proximal blind spots, often using the catheter to improve the level meter is installed to ensure the full range of measurement accuracy. Tank with overflow hole, then the overflow hole to probe the distance is greater than the blind spot on it. If there is no overflow hole, level the situation will be in full irrigation, you must ensure that the value of L is greater than the blind spot. Catheter diameter D to be as large as possible, the length L to be as short as possible, the proposed D / L> 1 / 3. At the same time as much as possible to ensure no excess weld the internal catheter, protruding pipes and tanks at the interface to be no glitches. Recommended a short tube with a cutting angle (45 ° is best), so that a variety of confounding factors to a minimum.
