•
Do not use any excessive force when closing the sensor lid; while the tube should be fixed
within the channel, it must not be crammed into it as this might affect the measurement
values or damage the sensor.
•
Try not to pull the tube into position as this might deform the tube and/or create cracks in
the material which, in turn might impact the ultrasonic signal.
•
Ensure that the lid is fully closed to avoid fluctuating coupling and flow values.
Please note:
•
To avoid flow turbulences and associated measurement inaccuracies, it is necessary for the tube to be
straight in the area near the BioProTT
TM
Clamp-On SL.
→
Ideally, the tube should be straight for a distance of at least 15 x the inner diameter (ID) of the tube on
either side of the sensor.
For more information regarding sensor positioning and other possible measures to optimize and maintain
the accuracy of the BioProTT

FlowMeasurement System, see our TechNote titled "

6.4 Use of the BioProTT
TM
Clamp-On SL
For further details concerning the use of the BioProTT
TM
Clamp-On SL and how to carry out flow
measurements, please refer to the user manual of the respective BioProTT
TM
evaluation device.
Make sure to follow the steps described below and to heed the warnings included in them in
order to ensure the highest possible accuracy of measurement values.
In addition, always ensure that:
•
the medium temperature is the temperature the sensor was adjusted and calibrated for.
•
a zero flow adjustment is carried out before each measurement
and whenever possible
without disturbing your process.
Before starting the flow measurement:
1.
Make sure that only tubes specified for the BioProTT
TM
Clamp-On SL are used as this is the tube type the
BioProTT
TM
Clamp-On SL is adjusted and calibrated for.
→
The tube that is used during the measurement must be the one indicated in the set calibration table.
→
The tube type(s) the sensor was adjusted and calibrated for can be found in the Calibration Information
Sheet, which is part of every sensor order.
2.
Before each measurement, the cables, connectors and pins must be checked for breaks or damages
as this could result in wrong measurements. Do not use the BioProTT
TM
Clamp-On SL if you detect any
damages.
