3. MOUNTING
3.1 General
The Manual Sighting and Reading Table can be mounted in two ways: floor fixation or wall
fixation.
No matter in what way it is mounted, it must be ensured that directions X and Y correspond to
the expected directions, Y being typically oriented directly Upstream/ Downstream.
The base plate must be leveled using a spirit level. For the software to work over the full range
(±25 mm in both X and Y axes), the base plate must be positioned so that the initial position of
the pendulum wire is a close to the Origin Point shown in Figure 1 as possible. (Due regard
should be given to the current position of the pendulum wire within its annual cycle of
movement due either to temperature or reservoir level).
The base Plate should be installed 1.5 to 1.6 meters above the ground and a one-meter space
should be kept free in front of the steel scales
3.2 Floor Mounting
In most cases, this mounting method can be used when the pendulum wire is far away from the
wall. When mounting this bracket, users can make adjustment in X/Y direction in order to keep
the pendulum wire close to the origin position on the base plate.
Use angle steel, (40 mm x 40 mm or 45 mm x 45 mm), to fabricate a bracket based on the
dimensions and structure shown in Figure 2.
It is recommended that the bracket should measure 296 to 306 mm wide and 300 mm deep and
its height is considered proper if operation and reading are convenient. It is recommended that
the height should be around one to one and a half meters. Where a higher bracket is needed, the
bracket can be mounted on a platform poured with concrete (refer to Figure 3). The slotted hole
in the brackets should be 50 mm long.
Except for important dimensions, users may adjust the dimensions and structure of the bracket
providing that the new dimensions do not affect mounting and operation.
