2 Installation Instructions
2.1 Planning the Installation
2.1.1 General Guidelines
The viscosity transmitter will function at its best if you take note of the following
general installation rules.
• Do not install the transmitter where it can be subject to mechanical
damage.
• The media must be well mixed and may not contain particles larger than
permitted by selected measuring basket, see the physical specifications in
section 1.2: Technical Data.
• The flow velocity of the media should not exceed 2 m/s (6.6 ft/s).
• Do not install the transmitter in a downflow section of pipe, since there
might be air in the pipe.
• The viscosity of non-Newtonian media is affected by the velocity of the
media in the pipe. For best possible measuring result on these types of
media, we recommend that the media velocity in the pipe is kept as low
and constant as possible.
• Make sure that the transmitter is equipped with suitable sensor blade for
the topical viscosity.

2.1 - Planning the Installation
10 M2079/3en Installation Instructions M2079/3en
© BTG 2016
2.1.2 Process Site Selection
Install the transmitter in a part of the piping where no disturbances, for exam-
ple air or vibrations, are expected. Make sure that the straight pipings before
and after the transmitter are sufficiently long, see fig 4.
Piping for extraction of partial or return flow should always be inserted in the
main pipe after the transmitter, see fig 4.
In those cases where the medium contains particles, always install the trans-
mitter after the filter.
NOTE!
When measuring on non-Newtonian media, do note that a pump, valve or pipe
elbow can cause a treatment of the medium. The treatment varies due to the
flow velocity. If the transmitter is installed too close to the pump, valve or pipe
elbow, it may seem as if the transmitter is dependent on flow velocity, when the
real case is that it measures on a medium that has a viscosity that has been
affected by the flow velocity, which in turn affects the shear rate.
If the medium is non-Newtonian we recommend the usage of a pump that
leaves variations as small as possible in the flow velocity.

The transmitter can also be installed in a bypass line, see fig 5. This is recom-
mended on media that tend to dry at process interruption, and when mounting
the transmitter to the measuring vessel on slender pipe lines, that is pipes with
a diameter less than 100 mm (4").

If the transmitter should be installed into the wall of a tank or bigger vessel
there is a big risk of influence from the turbulence in the tank. The transmitter
will then need a deflector to work properly.
See fig 6 for example on how such deflector can look.

It is possible to install the transmitter in a vertical, horizontal or sloping pipe,
see fig 7.
Always install the transmitter to the side of horizontal or sloping pipes to avoid
that air bubbles disturb the measurements. Simultaneously the cooling of the
transmitter at high medium temperatures is increased.
NOTE!
Never install the transmitter on the top side of horizontal or sloping pipes.
