4. Allow at least 50 cm clearance to the sensor housing, to be able to take out the measuring sensor
for service.
5. The sensor needs a stable environment to act as a counterweight for the pendulum movement.
The support must prevent movement and excessive vibrations of the ViscoSense

3 housing,
especially movement in the direction of the pendulum movement (see drawing- angular movement
around the sensor axis). Therefore there must be two supports to the inlet and outlet perpendicular
to the pipe and perpendicular to the ViscoSense
®
3. If one support would be used the lateral
vibrations would be converted to angular vibrations and the situation would be made worse instead
of better.

The angular position of the supports must always be 90° in relation to the sensor.
The distance from the flange to the support should be two times the diameter of the pipe.
