Magnified view of signals
Point
1. Startup is kept within 3 to 5 waves. If startup of signals is not good, piping parameters may not be entered
properly, or the mounting status of the detector may not be good. Check piping parameters and the mounting
status of the detector by referring to the section that “The reading does not change even if the flow rate changes”
(error display on LCD) of 6.2.3. Measurement value error.
2. The peak (amplitude) does not fluctuate. If the peak fluctuates vertically, air bubbles may be mixed in. Take
measures by referring to the part of “mixing in of air bubbles” in the section that “The reading does not change even
if the flow rate changes” (error display on LCD).
3. The time base does not fluctuate. If the time base fluctuates, the signals may be affected by turbulent flow or drift
current. Take measures by referring to the section that “The reading fluctuates abnormally even if the flow rate is
kept constant” of 6.2.3. Measurement value error.
