Circuit Hardware
Error
* Hardware problem
* Contact the manufacturer
*I No Signal
* Unable to receive signal
* Loosen contact or not
enough couplant between
transducer and pipe surface.
* Transducers installed
improperly
* scaling on inner pipe wall is
too thick.
* new changed liner
* Make sure the transducer is in tight
contact with pipe surface, the couplant is
enough .
* Polish the pipe surface and clean the pipe
surface. Clear paint,rust.
* Check original installation parameter
settings
* Clear the scaling or change the pipe with
thick scaling,normaly change to another
measurement point that has little
scaling,the meter can work normaly.
* Wait until the liner has been solidified and
then test.
*H lower signal strength
received
* lower signal
* causes are the same with
code “I”
* solutions are the same with code “I”
。
*H poor signal quality
received
* poor signal quality
* include above all caused
* include above all solutions
*E
The current of
Current Loop is Over
20mA (not influence
the measurement if
not using current
* 4-20mA current loop output
overflow 100%
* Improper settings for current
loop output
。
* Check current loop settings on M56. or
Confirm if the actual flow rate
is too high.
