Check to be sure the mounting spacing is accordance with the display in menu M25 and the
transducer is mounted at the pipe’s centerline on the same diameter.

Pay special attention to those pipes 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
indeed fluid in the pipe or the transducer is not too close to a valve or elbow, and there are
not too many air bubbles in the fluid, etc. With the exception of these reasons, if there is still
no signal detected, the measurement site has to be changed.
