9 Channel Master Installation
This section is a guide for installing the Channel Master. Use this section to
plan your installation layout. We recommend you distribute this informa-
tion to your organization’s decision-makers and installation engineers.
9.1 Mounting Plate Assembly
Assemble the mounting plate by connecting the four standoffs to the base
plate (see Figure 24). Mount the standoffs with the flat end toward the base
plate. Use the provided M6x1.0x16 flat head screws.

9.2 Orientation and Tilt
The Channel Master must be mounted with its transducer orientation in the
horizontal direction. That is, the two larger transducers, which are for water
velocity measurement, must be looking horizontally (also called side-
looking). The third transducer, which is for water depth measurement, must
be looking up towards the water surface.
We recommend the Channel Master be mounted with its Y-axis of the in-
strument coordinate perpendicular to the direction of the channel mean
flow. The Channel Master X-axis (direction from Beam 2 to Beam 1)
should be parallel to the channel main flow direction (Figure 25, page 43).
