4.0 INSTALLATION
4.1 Installation of Flow-Through Sensors
Refer to Dwg# N105-60
4.1.1 Flow-through sensors are secured with the supplied compression fitting. The
insertion length is adjustable within the limits shown in DWG# N106-114. If your
sensor has a cross hole it must be inserted far enough to be sure the cross hole is
in the solution. Use thread sealant such as Teflon tape on the sensor and the
mounting hardware threads.
4.1.2 Install a 3/4” NPT tee into the process line. Tee material should be compatible with
sensor materials of construction for best chemical resistance and
pressure/temperature ratings. A 1” NPT tee with a 1x3/4” reducer may also be
used.
4.1.3 Electrically connect sensor to the instrument as described in Section 4.3.
4.1.4 Remove the protective cap from the sensor and calibrate the system as described
in the instrument operating instruction manual before installing sensor into the
mounting tee.
4.1.5 Screw sensor and fitting into the tee. Locate end of the sensor or cross hole in
sensor at the approximate center of the stream.
If you disassembled the cell be sure to re-assemble the components as shown in DWG#
N105-61
4.2 Installation of Submersion Sensor
Refer to Dwg# N105-60
4.2.1 Submersion sensors are designed for use in tanks, suspended from the top of the
tank. Mounting hardware, model MHMSC is available from AquaMetrix. It consists
of 3/4” CPVC pipe, 24” long with a cable clamp and a wire-mounting bracket.
4.2.2 Run the sensor cable through the desired length of 3/4” CPVC pipe and screw on
the cell using a thread sealant to keep the cable end of the sensor dry.
4.2.3 Electrically connect the sensor to the instrument as described in Section 4.3.
4.2.4 Remove the protective cap from the sensor and calibrate the system as described
in the instrument’s operating instruction manual before installing sensor in the tank.
4.2.5 Place the cell in the liquid and secure to the tank in an appropriate manner using
the wire bracket provided with MHMSC hardware.
