Fig. 111 Starting measurement mode
Standard start-up is now completed.
4.2.9 Signal waveform
Checking the signal waveform allows an assessment on the quality of the received
ultrasonic signals.
To enable the display on the screen, open the device file of the used FLOWSIC100 type.
Select the menu "Diagnosis/Sensor Values" in operating mode "Measurement".
The ultrasonic signals of both transducers are displayed as unconditioned signals
under "Signal Display". If the option ‘‘View Envelope” is checked, the envelopes of both
transducers are displayed. The signal waveform should match the waveforms in the
Fig. 112 to Fig. 121, depending on the device type.
NOTICE:
For internally cooled and purged sender/receiver units, the purge air supply
has to be guaranteed during facility downtime. Otherwise remove the sender/
receiver units from the duct.
