5.
The coupling must be checked before each measurement and must be ≥50 %.
6.
A zero flow adjustment must be carried out before each measurement to avoid possible offsets from the
measured values.
For the zero flow adjustment,
–
the sensor must be clamped in the correct installation position at the location intended for it.
–
the tube must be filled with liquid (i.e. the coupling must be ≥50 %), but the liquid must not move.
–
ensure that no air bubbles are in the tube.
–
allow sufficient time for the system to adapt to ambient conditions.
Only then is the system ready for measurement.
During the flow measurement:
•
Ensure that the coupling is within the operating range of 50 - 100 %. If the coupling falls below 60%, the
BioProTT
TM
FlowTrack SL will not display a flow value.
•
The stated measurement accuracy of the BioProTT
TM
Clamp-On SL is only valid if the specified tubes
are used at the specified medium temperature the sensor was adjusted and calibrated for and if the
recommended outlet section is respected.
•
Any changes in the medium itself or its temperature can cause errors or anomalies in the measurement.
•
It must be ensured that the same parameters are used on-site as were used during the adjustment and
calibration process.
•
While it is possible to carry out measurements outside of the specified flow range,
em-tec GmbH cannot guarantee that resulting flow values will be within the given accuracy range.
The parameters of the connected BioProTT
TM
Clamp-On SL and the selected calibration table are shown on
