General requirements
Smooth surface is important
Mounting screws or bolts must not be extruding from the transducer or the area
immediately around it.
Make sure that the surface of the transducer face, the installation hardware used to mount
it, the hull plating and the putty around the transducer is as even and smooth as possible.
Obstructions on these surfaces will create problems with turbulent flow.
Use mounting and clamping rings whenever provided
Circular transducers may be provided with mounting and clamping rings, or with
drawings to allow for local production of these.
The mounting ring is welded to the hole prepared for the transducer, while the clamping
ring fits around the edge of the transducer body. Bolts through the clamping ring into the
mounting ring will secure the transducer between them.
Note that several transducers use direction guides to allow correct mounting.
Use a mounting plate whenever provided
Certain transducers may be provided with a mounting plate, or with drawings to allow
for local production of this.
The mounting plate is welded to the hole prepared for the transducer. Bolts through the
transducer body into the mounting plate will secure the transducer.
