Detect No Signal
(1)No Signals detected
(2)Transducers installed
improperly
(3)Too much fouling
(4)Pipe liners are too thick.
(5)Transducer cords are not
properly connected
(1)Polish the pipe surface
and clean the sport.
Remove paint
(2)Make sure the couplant
is enough
(3)Make sure the
transducer is in tight
contact with pipe surface
(4) Check the transducer
cables
(5) Check installation
parameters settings
(6)Find a better
measurement site. Newer
pipe, no corrosion, no
depostion

PoorSig Detected
(1)Poor signal detected
(2)Transducers installed
improperly
(3)Too much fouling
(4)The pipe liners are too thick.
(5)Problem with transducers
cords
(1)Relocate measuring
place
(2)Clean the spot

E
Current of loop is bigger
than 20mA.
4-20mA loop output over 120%
Improper settings for current
loop output
(1) Ignore it if current loop
output is not used
(2) Check current loop
setting in M56
(3) Confirm if the actual
flow rate is too high.
Q
Frequency Output Over
(1) The frequency output is over
120%
(2) Improper settings for
frequency output
(3) The actual flow rate is too
high
(1) Ignore it if frequency
output is not used.
(2) Check the values
entered in
M66,M67,M68,M69
(3) Use a larger value in
M69 if needed.
(4) Confirm if the actual
flow rate is too high.
