Quick Start Guide
Fitting the submersion shield
Step 1: Check the transmitter mounting
The transmitter mounting must ensure that the transmitter is firmly kept in place,
and ideally at 90 degrees to the liquid surface. This is essential for an air pocket to
be formed at the base of the shield as flood water rises and passes it.
Step 2: Lubricate both O-rings before fitting the shield
A suitable lubricant such as Dow Corning MS4 silicone grease may be used. If this
is not available, a suitable water-based lubricant or liquid detergent may be used.
Step 3: Fit the submersion shield
Follow this procedure:
1. Align the shield opening with the transducer cup, ensuring that the red O-ring
is above the grey O-ring (
Figure 3
, left image).
2. Hold the transmitter and firmly push the shield upwards onto the transducer
cup, until the red O-ring is on the transducer cup (
Figure 3
, middle image).
3. Continue pushing the shield upwards firmly until the red O-ring engages with
the recess on the transducer cup (
Figure 3
, right image).
