3. Installing
3.1. General principles
The sensor model is selected according to the size and
pressure rating of the pipeline. Flow-through models
are FT50/2", FT80/3", FT100/4", FT150/6", FT200/8",
FT250/10" and FT300/12". These can be installed to
the following pipe flanges:
Standard model
– DIN PN10
– DIN PN16
– ANSI Class 150
– JIS 10K
High-pressure model
– DIN PN100
– ANSI Class 600
– JIS 63K
For laboratory follow-up, it is important to use a good
sampler (e.g. NOVE) and install it in accordance with
the Valmet TS installation instructions.
NOTE: Before installing the process coupling / sensor,
make sure that the process pipeline is empty and not
pressurized, and that installation work can be carried
out safely!

3.2. Choosing the installation site
When choosing the installation point, pay attention to
the following:
– Never install the sensor to the suction side of a
pump, or to a tower.
– Free straight pipe section after any changes in the
pipeline profile.
– Space for the sensor housing.
– TCU must be installed close to the sensor. The
length of the normal sensor cable is 10 m (33 ft), a
30 m (98 ft) cable is available as option.
Also pay attention to the following specifications:
– Process temperature max. 100 °C (212 °F).
– pH 2.5...11.5.
– Recommended process pressure is 1.5…16 bar
(22…232 psi) to eliminate the effect of air bubbles.
– Conductivity according to sensor specifications.
– Pressure rating of the sensor: FT models
PN16/PN100
Inspecting the installation:
– Make sure that the installation point and sensor po-
sition are in accordance with the instructions.
– Make sure that the FLOW arrow on the sensor
housing is aligned with the process flow direction.
– Protect the sensor and TCU from direct heat radi-
ation and direct sunlight.
– Before start-up, make sure that the seals between
the Valmet TS flanges and process flanges are cor-
rectly installed and the mounting bolts tightened.
– Make sure that ground wire is connected under the
flange bolt (Fig. 1).
– Open the shield (Fig. 1 A) to connect the TCU cable.
Close the shield (Fig. 1 B) before connecting power
to the system.
Sensor installation to a vertical and horizontal pipeline
is illustrated in Fig. 2 and 3.
