The Opti-Trace
is rated for light industrial environments. Do not install within 10
feet/3 meters of devices such as large generators that generate a strong
electromagnetic field.
It is extremely important to eliminate air entrapment in the sample line. The best way
to accomplish this is to sample from the center of the pipe or from the side of the
pipe.
The unit should not be installed in direct sunlight; this could cause the internal
temperature of the unit to be significantly higher than ambient and produce errors or
damage the components (Note the maximum environment temperature is specified at
120
o
F/49
o
C).
Do not mount this instrument on vibrating walls or surfaces. Damage can occur to
critical components.
Mechanical Connections
Refer to Figure 9, Appendix D for the location of the required mechanical
connections.
Two ¼ inch NPT pipe connections are provided for ¼ inch PVC pipe hook-up. The
sample outlet line is ¼ inch female; the sample inlet line is ¼ inch male shut-off
valve.
Plumbing Kit Inlet/Outlet Size Information
The outlet line is ¼ inch NPT (female) to connect to user-supplied ¼ inch male
piping; the inlet line is ½ inch NPT (female) to connect to user-supplied ½ inch male
piping (see Figures 7 and 8 on pages 19 - 20).
IMPORTANT
:
1.
Sample discharge should flow to an unrestricted drain. Pipe rises greater than 10
feet [3 m] should be avoided. Ensure that the drain cell does not allow the water
to siphon off, with the potential risk of the sample water draining out faster than
the flow rate through the sample cell.
2.
Draining into a pressured system is not recommended.
Calibration and Operation
This procedure is in 3 parts:
1.
Section 1 will describe how to calibrate your data collection system to the signal
supplied by the Opti-Trace. It is assumed that your data collection system
provides a method to do a linear calibration.
