Displays the measurement value of transit time, T1 (forward time), and
T2 (reverse time) from the piping setting.
Press the

Displays the measurement value of average transit time, T0, and
transit time difference, DT.
Press the

Displays the calculated value of pass time of the substances other
than fluid, Ta, and angle of incidence of the fluid, .
Press the

Displays the calculation value of sound velocity in fluid, Cf, and
Reynolds number, Re.
Press the
▼
Displays the analog input pressure AIp and analog input temperature
AIt.
Displays the calculation value selected with the AI range. (See section
4.10.1)
Press the

Displays the flow velocity distribution correction coefficient K and flow
velocity V1.
Press the

Displays flow velocity V2 and flow velocity V3.
Press the
▼
Displays the intensity of received signals.
The larger the value, the larger the intensity of received signals.
Normal measurement values fall in 43% or more.
If the display appears as 0%, no signals are being received.
It is likely that ultrasonic propagation is not possible due to reasons
such as pipe rust.
