check whether the parameters are
entered correctly, especially the sound
velocity of the fluid and the installation of
the transducers. This data is of no use
before the system is ready.
Fluid Sound Velocity
Display the measured fluid sound
velocity.
properly or if the parameters
have
been entered correctly.
Total Time and Delta Time
Display the measured ultrasonic
average time (unit: nS) and delta time of
the upstream and downstream (unit: nS)
time. The velocity calculation in the
flowmeter is based on the two
readings.The delta time is the best
indication that the instrument is running
steadily. Normally the fluctuation in the
ratio of the delta time should be lower
than 20%. If it is not, it is necessary to
check if the transducers are installed
