MODEL 242
1.4 INSTALLATION
In the instructions below, the Junction Box is installed
after the sensor is bolted into the process line. If appropri-
ate for the site and final mounting configuration, the
Junction Box can be installed prior to bolting the sensor
into the process line.
The liner of the Model 242 sensor can be damaged if mis-
handled. Do NOT place any object through the liner for
the purpose of lifting the Model 242 sensor.
Support structures should be installed as appropriate on
or around process pipes and sensor location to sufficient-
ly support the weight of the sensor during installation and
minimize strain on adjacent process pipes during the
operational life of the sensor.

CAUTION
FIGURE 1-5. DIMENSIONAL DRAWING
Installation of the Model 242 Flow Through Sensor is simi-
lar to installation of a section of pipe. Consequently, be
prepared to use tools, supplies, equipment, and tech-
niques similar to those used to install process pipes. Use
common piping practices to minimize torque and bending
loads on process connections. Observe all applicable
safety standards. Dimensional information is shown in
Figure 1-5 below. Refer to Figures 1-6 to 1-8 for assembly
and installation diagrams.
1. Allow at least four pipe diameters of straight pipe run
on either side of the sensor.
2. Install the sensor so that it is filled with process liquid
at all times when measurements are being made.
Avoid downward flow as such a configuration might
leave the sensor partially empty.
3. Use a sling and hoist to lift and position the sensor.
