Make sure the maxi-
mum velocity range
is within the range
listed in Table 3-1 on
page 3-4 for the pipe
size and pressure.
Check programming
and transducer spac-
ing. If programmed
value is outside of
limit, change the lim-

trical problem.
Check for source of
electrical interfer-
ence. Check electron-
ics with a test
flowcell.Check to see
if the velocity is above
the maximum value.
Check to see if the
pressure is above the
minimum required
pressure for the pipe
