2. Installation
Before any attempt is made to install the sensors the following directions must be read and understood.
The vibrating wire transducer is very sensitive and correspondingly fragile, and must be handled with great care.
Figure 2. Installation Details
2.1 Install the mounting brackets
The first step is to install the mounting brackets. It is important to install all chambers at about the same elevation
at the start of the monitoring program since the range of the transducer is limited and the amount of adjustment is
small.
The chamber mounting bracket is designed to be bolted to a wall or a pedestal and should be firmly attached with
either anchor bolts or epoxy grouted studs. The chamber assembly has three threaded supports, which allow for
precise leveling of the system. When all brackets have been installed, the chambers should be attached using the
three threaded rods and nuts supplied. Tighten one nut against the base of the chamber and use the other two nuts
one on either side of the bracket. Level by placing a spirit level on the chamber cylinder, and then adjust the level
with the nuts on the threaded rods that pass through the brackets. The unit must be / - 1.5 degrees of
vertical for proper operation. When the cylinder is level, tighten the nuts from both sides of the bracket.
2.2 Attaching the fluid lines
The next step is to attach the fluid lines. This is usually accomplished by running a large diameter pipe between
chambers and having T connections and ball valves at each chamber location. The interconnecting pipe must be
kept below the chambers and, if possible,
be slightly inclined from one end to the other
. The first chamber, at
the lowest end, uses the filling valve which has attached to it the valve for draining and filling. The chamber valve
