(2) Abnormal waveform
The receiving waveform is not covered within the
range of the ultrasound waveform.
It is displayed as “E2: CALCULATION ERROR”
or “E2: RECEIVED SIGNAL ERROR”.
Check the pipe setting and sensor mounting di-
mensions.
When ultrasonic receiving signal waveform is
weakened by the effect of rust in the pipe, abnor-
mal waveform may result. Raise the transmission
voltage and perform measurement. (See page 36).
(3) No received signal
The waveform is free of the received waveform, and
this is the waveform to which the noise is expanded.
The equipment cannot measure.
Ultrasonic waves may not be transmitted because of
insuffi cient water volume or rust of piping.
Peak value of
about 5528
to 6758
Noise level
[Remark] Check to judge whether ultrasonic receiving signal waveform is
normal or not
(1) Normal waveform
The receiving waveform is free of noise, normal mea-
surement can be performed.
The receiving
waveform is
being inter-
rupted.
