During the Initial Makeup the flow meter decides that the level of the receive signal is
insufficient for proper operation. Some reasons for low signal are:
Invoking [Install completed?] on an empty pipe.
•
Coupling compound insufficient; not applied or evaporated.
•
A disconnected or broken transducer cable.
•
The pipe needs to be conditioned at the mounting location.
•
Flush out large air bubbles.
•
The Xdcr cables are defective or not connected to the correct channel.
•
The Set Empty routine performed when pipe was NOT actually empty.
•
If you locate and correct the improper condition immediately, press <ENT> to resume the
installation procedure. Otherwise, press the <Left Arrow> to abort the installation and
conduct a thorough investigation.
If it appears that the flow meter cannot complete an Initial Makeup it means that the pipe
and/or liquid conditions do not permit a receive signal that meets the flow detection
standards. The system will not operate. Attempt to improve operating conditions by
reinstalling the transducers at a different spacing offset, or even at a different location on
the pipe.
Switching from Reflect to Direct Mount may solve the problem. However, operation may
not be possible if there is poor liquid or pipe wall sonic conductivity.
