Explanation of measurement data
• Signal power
Displays the intensity of received signals.
The larger the value, the larger the intensity of received signals.
Normal measurement values fall in 35% or more.
For 0%, there is no received signal.
Ultrasonic waves may not be transmitted because of insuffi cient water volume or rust of piping.
• Trigger level
Displays the detection level of received waveform.
• Signal peek
Displays the peak value of received waveform.
Normal stable values fall within the range from 5528 to 6758.
If the value fl uctuates signifi cantly, objects that constitute barriers against ultrasonic wave trans-
mission such as air bubbles or foreign matter may be contained in the fl uid.
Stop the fl ow, and if the measurement is found to be normal, then there is a possibility that air
bubbles are entrained.
• Fluid sound velocity
Displays the calculated value of the fl uid sound velocity.
