Adjustment of the distance between the measuring barriers
The recommended distance between measuring barriers will be displayed. The measuring barrier distance is the distance
between the transducers of the transducer pairs A and B.
• Mount the transducers of transducer pair B on the pipe. Position the transducers according to the displayed distance
between the measuring barriers. The distance has to be adjusted with an accuracy of 1 mm. In case the recommended
distance between the measuring barriers displayed by the transmitter cannot be set because of the transducer size,
mount the transducer pair B at the smallest possible distance to transducer pair A. Make sure to keep a few millimeters
distance between the transducers of measuring barrier A and B. The transducers should not touch.
• Enter the distance between the measuring barriers.
• Press ENTER.
Check of the transducer distance for transducer pair B
The recommended transducer distance for transducer pair B will be displayed.
• Check whether the transducer distance of transducer pair B corresponds to the value displayed by the transmitter. The
transducer distances of transducer pair A and B have to be equal.
• Correct the transducer distance, if necessary.
• Press ENTER.
Parameter search
Before starting the measurement, the transmitter performs a parameter search. This process takes about 10 minutes. The
remaining time is displayed.
After completion of the parameter search, the measurement is started. The measured values are displayed.
