3.3.4 Instructions for Tube Mounting
1.
Assure that the correct tubing type is used by
checking the according tubing information on
the calibration sheet delivered with the clamp-
on sensor.
2.
For a proper and accurate flow measurement it
is very important that the ultrasonic beam is not
disturbed by particles, dust and air in the
measurement path, which would result in
reflections
and
lead
to
a
wrong
flow
measurement. Specifically, it must be assured
that in the clamp-area between tubing and
sensor no particle or dust is squeezed in during
the clamp-on process.
3.
Therefore, check the cleanliness of the surface
area where the ultrasonic beam leaves the
sensor and if necessary clean it with alcohol.
CAUTION
Do not use aggressive cleaning agents, which could
attack the sensor surface and its parts. Alcohol has
been tested and approved as an adequate cleaning
agent.
4.
Check the tubing surface area, which is
clamped into the sensor, for cleanliness and
inertness. Assure that no particle or dust is
present. If necessary, clean the tube with
alcohol or an adequate cleaning agent specified
by the tubing manufacturer.
5.
Properly align the tubing with the clamp area of
the sensor and avoid bending or squeezing the
clamp area.
