3. INSTALLATION OF
FU20-FTS/MTS
For optimum measurement results, the
FU20-FTS/MTS should be installed in
a location that offers an acceptable
representation of the process composition
and
DOES NOT
exceed the specifications
of the sensor. The FU20-FTS/MTS
is designed with 3/4” NPT threaded
connections on both ends of the sensor
to allow installation in a wide variety of
applications.
3.1 Typical installation
The FU20-FTS/MTS sensor is designed
for versatile in-line, immersion or off-line
installation. For best results the FU20-FTS/
MTS should be mounted with the process
flow coming towards the sensor, and
positioned at least 15° above the horizontal
plane to eliminate air bubbles in the pH glass
bulb (see Figure 1).

3.1.1 Preparing the sensor for use
Remove the sensor from its shipping box
and slide of the so-called ‘wet pocket’, the
tube filled with solution to prevent drying out
of the measuring elements during shipment
or storage. Although the sensor is factory
calibrated, it is recommended to calibrate
the sensor before first use.
A general calibration procedure is described
in Section 6 of this Instruction Manual.
3.1.2 Mounting the sensor
The simplest mounting is to use one of
the 3/4” NPT threaded connection of the
sensor. Apply Teflon tape to the appropriate
threaded end, then install the sensor in the
process (see Figure 2).
Note:
Do not overtighten the sensor body.
