Solution
R
System Normal
No error
I
Detected No Signal
1) No detected signal 2) Sensors installed improperly 3)
Too many encrustations
4) Pipe lining too thick 5)
The transducer cables are not properly
connected
1) T
ight the transducers on the pipe
2) Check the setted parameters 3)
Clean the pipe surface and remove any rust
4) Change installing position
5) W
