provided by properly installing the transducer into the clamping fixture. Care must be taken during
installation to ensure that protection is provided.
The last installation step is mounting the transducers into the clamping fixture. To mount the transducers into the UCF,
complete the following steps:
1. Apply a thread sealant to the transducer threads. A sealant is not required for installations in the USA, but a sealant
must be used for installations in EU countries.
2. Before mounting the transducers into the UCF, thread the electrical junction box onto the BNC connector end of the
transducer. Make sure that at least five full threads are engaged. Be sure to orient the cover of the junction box so it
is accessible to make cable connections after the transducer is installed.
3. On one of the transducers, apply a thin bead of couplant down the center of its face approximately the size of a
toothpaste bead.
Note: To prevent the loss of couplant, do not slide the transducer with couplant along the surface of the pipe when
mounting.
