Possible
Problem
Programming
error, poor flow
conditions, or
bad transducer
spacing.
If too high -
electronic fail-
ure. If too low -
flowcell, elec-
trical problem.
Excessive parti-
cles or liquid
present in fluid.
A lot of second
phase present
Cause
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-
its as described in
Chapter 9 on page 9-
32. See Flowcell
Problems on page 10-
9 and Transducer
Problems on page 10-
11.
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
OD/WT. If unit still
fails to operate, con-
tact the factory.
See Flowcell Prob-
lems on page 10-9.
