Do not remove the transducer housing locking ring to ensure that the transducer
housing does not unscrew from the meter body during this process. Place a wrench on
the 1inch hex of the transducer retainer and unscrew it from the transducer housing.
4.
Use a pair of needle nose pliers to grab the indexing key of the transducer and pull the
transducer from the housing.
5.
For LT-05 transducers only, place a small amount of the Dow Corning 111

Silicone
grease (P/N 1-360-01-651) on the face of the transducer to be installed. Using your
finger spread the silicone grease over the face of the transducer to create a thin, even
layer of silicone grease on the surface of the transducer face. There should be no gaps or
mounds of the silicone grease on the face of the transducer. Wipe off any excess silicone
grease from the sides of the transducer.
