Rosemount 3107/3108 Submersion Shield
The Rosemount Submersion Shield (03107-7003-0001) is recommended for
installations, e.g. wet wells, where a 3107/3108 transmitter may be at risk of
being flooded.
It is easily fitted over the transducer cup, but requires the transmitter to be kept
firmly vertical so that flood water causes an air pocket and keeps the transmitter
face clear. The transmitter can then function normally when the flood water
subsides.
Figure 1 on page 2 shows an example application with the submersion shield
already fitted to a Rosemount 3107/3108 transmitter, which is then mounted on
a Rosemount Head Verification Device.

Failure to follow these installation guidelines could result in death or serious injury

Use the equipment only as specified in this manual. Failure to do so may impair the protection
Electrical shock could cause death or serious injury
Make sure the main power to the transmitter is off and the lines to any other external power
provided by the equipment
source are disconnected or not powered whilst installing the submersion shield
