1）The distance from the transducer emission surface to the low liquid level should be less than the range of the selected instrument;

2）The distance from the transducer emission surface to the high liquid level should be greater than the blind spot of the selected instrument;

3）The emission surface of the transducer should be parallel to the liquid surface;

4）The instrument is installed in the center of the canal or on a still water well.

5）The instrument needs to be installed upstream of the weir plate or weir groove.

3.3 Installation precautions

1）The instrument casing should be securely connected to the ground;

2）Wire and cable protection pipes should be protected to prevent excessive water accumulation;

3）Although the instrument itself is equipped with lightning protection devices, it is fortunate to install dedicated lightning protection devices at the inlet and outlet of the instrument when used in areas with frequent lightning strikes;

4）When the instrument is used in particularly hot or cold places, where the ambient temperature may exceed the working requirements of the instrument, it is advisable to install high and low temperature devices around the level gauge;

3.4 Weir trough, weir plate

Requirements for the production of weir channels and weir plates:

Suggest using fiberglassPVCOr stainless steel or other materials can be used to make weirs or grooves. The dimensions of triangular and rectangular weirs should be accurate, and the surface facing the inlet side should be smooth; The dimensions of the throat section of the Bacher groove should be accurate, and the surface inside the groove should be smooth.

Bracket installation and flange size

Note: The size specifications may vary depending on the instrument and transducer, and any discrepancies will be notified in advance.
