Select sensor type:
• >NIS-V200R (300mm)<, >NIS-V200R (200mm)<, >NIS0V200RL<, >NOS-V2005<,
>NOS-V3005<, >NOS-V4005<, >NOS-V20B<, >NOS-V30B<, >NIS-V280K<, >NIS-
V300K<, >NOS 500kHz< and >NOS 200kHz<
The values for the NIVUS sensors themselves are pre-set and cannot be selected or
changed.
• >User defined<
The values for >Angle<, >Frequency<, >Offset< must be specified.
Specialist knowledge required
The use of and settings for non-standard sensors require extensive expert knowledge and
require the use of NIVUS commissioning personnel or an authorized specialist company.
32.4.3 Sensor Mounting Position
Hints on the Mounting Angle
In horizontal pipelines do not use pipe bottom or pipe crown as mounting places (risk of
soiling, air bubbles).
NIVUS recommends a mounting angle of 45°.
Depending on channel profile, path arrangement and the number of paths it is necessary to
define >Mounting height< or >Direction<. The settings must be adjusted
for each path
indivi-
dually.
>Mounting height<
Sensor mounting height in channel profile (related to cross section); the sensor based on the
channel dimensions suggests mounting heights which, however, can be changed manually.
>Direction<
The direction specifies which of the both path sensors in flow direction is installed first or last
(related to cross section).
For sensor positioning both specifications are required as soon as they are indicated.

The following settings for length and angle in the same path depend on each other. Modifying
one changes the others.
>Distance across<
Distance from the sensor (centre piezo) to the opposite inner pipe wall
