INSTALLATION
First, decide whether the initial calibration will be done in the shop before installing the sensor or in the process piping
after installing the sensor. Refer to the Calibration section for information about in-shop and in-process calibrations.
NOTE
Install the sensor in a location where it will be completely filled with process liquid.
A vertical pipe run with the flow from bottom to top is best.
1.
Remove the grounding strap from the outer flanges. See Figure 1. Save the strap and all the hardware for
reassembly.
2.
Carefully remove the nuts, bolts, insulating bushings, and washers from the flanges. Save the parts. They
will be needed later and must be in good condi tion. Separate the flange sets.
3.
Remove and save the flange gaskets.
4.
Install the outer flanges on the process piping, observing the dimensions noted in Figures 2 and 3. Use pipe
joint compound or pipe tape to ensure the connections do not leak.
5.
Install a ½ inch FNPT thermowell in the process piping within 6 ft. (1.8m) of the sensor. For best results place
the thermowell as close as possible to the sensor.
6.
Position the sensor between the process mating flanges with the flange gaskets inserted between each set
of flanges. If the process piping is lined with a non-conductive material, a metal orifice plate (contact ring)
must be installed between the flanges. Consult the factory for more information.
7.
Align the bolt holes.
8.
Insert an insulating sleeve in each bolt hole. See Figure 1.
9.
Place a metal washer on each bolt, followed by an insulating washer. Insert the bolt through the insulating
sleeve.
10.
Place an insulating washer f ollowe d a metal washer on each bolt.

NOTE
Before tightening the bolts (step 11), be sure the flange gaskets are installed between the
system piping and the sensor and that the insulating sleeves and washers are in place.
For the sensor to operate properly there must no metal to metal contact between the sensor
and the process piping.
11.
Screw a nut onto each bolt and tighten according to the table. Follow the torquing sequence shown in Figure 1.
Do not over tight-
en the bolts.
12.
Connect the grounding strap between the two outer f langes us ing the screws and washer s rem oved in step 1.
If an orifice plate contact ring is being used, connect the shorting strap to the two contact rings.
13.
Install the temperatur e sensor in the thermowel l. Use Teflon tape on the pipe thr e ads . The insertion length is
adjustable from 1.4 to 4.0 i nches (36 to 102 m m) . The temperatur e sensing zone, which exten ds 1.3 inches
(33 mm) from tip of the sensor, must be inside the thermowell
