DATA DISPLAY
ENT
ź
Press the
ENT
key.
z Displays the transit time and the window value calculated from
the piping setting.
T0 C: 89 usec
WinC: 80 usec
ź
Press the
key once.
z Displays the measurement value of transit time, T1 (forward
time), and T2 (reverse time) from the piping setting.
T1: 0.000 usec
T2: 0.000 usec
ź
Press the
key once.
z Displays the measurement value of average transit time, T0,
and transit time difference, DT.
T0: 0.000 usec
DT:PUGE
ź
Press the
key once.
z Displays the calculated value of pass time of the substances
other than fluid, Ta, and angle of incidence of the fluid, T.
Ta: 0.0000 usec
Tf: 0.000°
ź
Press the
key once.
z Displays the calculation value of sound velocity in fluid, Cf, and
Reynolds number, Re.
Cf: 0.0 m/s
Re: 0
ź
Press the
key once.
z Displays correction coefficient of flow velocity distribution, K,
and flow velocity, V.
K: 1.3333
V: 0.000 m/s
ź
Press the
key once.
z 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.
If the display appears as 0%, no signals are being received.
Ultrasonic waves may not be transmitted because of
insufficient water volume or rust of piping.
AGC U: 0.00 %
AGC D: 0.00 %
ź
Press the
key once.
z Displays the peak value of received signal waveform.
Normal values stably fall within the range from 5528 to 6758.
If the value fluctuates significantly, objects that constitute
barriers against ultrasonic wave transmission such as air
bubbles or foreign matter may be contained in the fluid.
Stop the flow and check if normal value is resumed.
If so, there is a possibility that air bubbles are contained.
P/H U: 6143
P/H D: 6143
ź
Press the
key once.
z Displays the detection level value of received signal waveform.
TRG U: 25.00%
TRG D: 25.00%
ESC
Press the
ESC
key or the
key to display the measurement
mode.
