B. MOUNTING LOCATIONS ON THE PIPE
If the transducer is applied to
horizontal pipe, choose a mount-
NO
ing position at approximately 3
o'clock or 9 o'clock, assuming 12
o'clock to be to top of the pipe.
YES
YES
These positions typically provide
optimum
acoustic
penetration
into the moving liquid. As illus-
trated in Figure 2, placement at
the top or bottom of the pipe can
result in poor sound penetration
due to air pockets (on the top of
the pipe) or sediment (at the bot-
NO
tom of the pipe).
Figure 2
If the transducer is applied to vertical pipe, orientation
does not matter.
C. PIPE PREPARATION
Before the transducer face can be coupled to a pipe surface, an area
slightly larger than the flat surface of the transducer must be cleaned to
bare metal on the pipe. Remove all scale rust and paint. Thoroughly
dry and clean the mounting surface.
Note: For plastic pipes, such as PVC or PVDF, pipe preparation is
typically not required.
D. CONNECTING THE TRANSDUCER
Connect the transducer plug into the transducer jack. The connection
is polarized, so alignment of the keyway is necessary.
NOTE: The splash-resistant environmental seal is provided only when
the transducer plug is secured into the transducer jack. It is advisable
to make this connection before entering an area where the UFX may be
dropped into or splashed with liquid.
E. APPLYING THE TRANSDUCER
To ensure an acoustically conductive path between the transducer face
and the prepared pipe surface, a coupling compound is employed.
Enclosed with the UFX flow meter is a tube of Dow Corning 111 silicone
based grease. This grease is adequate for the majority of installations.
If an alternate grease is utilized, the grease must be specified not to
flow at the temperature of the pipe surface or the ambient conditions.
