Horizontal installation: When installed on the upper end of a horizontal pipe, ensure that the medium is full to prevent the probe from only touching the air but not the medium.

Inverted installation: When installed at the lower end of a horizontal pipe, it should be ensured that there is no sediment at the bottom of the pipe, so as to prevent the probe from being covered by sediment and unable to fully contact the probe.

Vertical installation: When installed vertically, it should be installed on the pipe section that flows from bottom to top.
