Low consistencies (SMART-PULP UL)
Low consistencies (see Section 7.1, Sensor Types)
are measured with sensor option UL. To measure
extremely low consistencies as accurately as
possible we recommend a bypass installation that
will provide the required flow velocity and stabilized
flow. You should be able to limit the flow velocity
between 0.1 and 1 m/s. This installation is illustrated
in Figure 1.1.2e.
The bypass line is connected to the process line with
20 mm pipes for max. 2% Cs consistency, and with
30 mm pipes for max. 3% Cs consistency. At higher
than 3% Cs consistencies you use 40 mm pipe.
Deflector must not be used with the UL sensor.
NOTE! Due to the risk of plugging, this installation is
not suitable for unscreened pulp.
High consistencies (SMART-PULP HL)
SMART-PULP HL, the transmitter for high
consistencies, is installed on the small-diameter pipe
section following the stock pump. This will ensure
sufficient flow velocity. See Figure 1.1.2d. This pipe
section usually includes other devices, such as a
flowmeter and control valve. Recommended
installation order is shown in Fig. 1.1.2d.
To protect the sensor, the deflector blade supplied
with the transmitter must always be installed in high-
consistency applications where standard process
coupling is used. In digester blow line installations
you have to use the blow coupling shown in Figure
1.1.3d. In that case you will not need a separate
deflector in front of the sensor.
