Transducer Placement
The following graphic shows the best placement of the XRS-5 transducer.
Locations
A. Primary location. This is the preferred location and should be used
whenever possible. The centre of the tank generally gives the most reliable
readings because there are fewer obstructions to provide false echos.
B. Alternate location. This location is used if the centre of the tank is already
in use or if the tank roof is too weak to hold the transducer safely.
C. Poor location. This is a poor installation location. The echos are shown
reflecting away from the transducer face.
