Correct use and installation of flanges:
Ensure that the flange is tightly connected to the instrument, with good sealing to prevent leakage and external interference.
The inner wall of the flange should be smooth to avoid additional reflections.
Reasonable use of extended pipes (sunken pipes/waveguide pipes):
Function: isolate steam, foam and dust; Reduce the temperature at the probe location; Avoid obstacles.
requirement:
The diameter of the pipe should be large enough (generally required to be greater than the maximum diameter of the sound beam, and it is usually recommended to have an inner diameter of ≥ 10cm).
The pipe wall must be smooth and vertical.
The bottom of the pipe must be open, and there must be sufficient distance (greater than the blind spot) between the bottom of the pipe and the low liquid level.
There should be no openings or welds on the pipe wall, otherwise strong interference echoes will be generated.
Cable entry and grounding:
Use appropriate cable sealing joints to prevent moisture and dust from entering the interior of the instrument.
Ensure good grounding of the instrument and improve its ability to resist electromagnetic interference.
