transducer is mounted at the pipe’s centerline on the same diameter.
Pay special attention to pipes formed by steel rolls (pipe with seams), since such pipe is always irregular. If
the signal strength is always displayed as 0.00, that means there is no signal detected. Thus, it is necessary to
check that the parameters (including all the pipe parameters) have been entered accurately. Check to be sure
the transducer mounting method has been selected properly, the pipe is not worn-out, and the liner is not too
thick. Make sure there is fluid in the pipe, the transducer is not too close to a valve or elbow, there are not too
many air bubbles in the fluid, etc. If there is still no signal detected after checking these reasons, the
measurement site needs to be changed.
Make sure that the flow meter is able to run properly with high reliability. The stronger the signal strength
displayed, the higher the Q value reached. The longer the flow meter runs accurately, the higher the reliability
of the flow rates displayed. If there is interference from ambient electromagnetic waves or the signal detected
is too poor, the flow value displayed is not reliable; consequently, the capability for reliable operation is
reduced.
After the installation is complete, power on the instrument and check the results accordingly.
