STATUS OF FLOW READING: HIGH OR LOW
Is the flow reading showing a rate that is lower or higher than expected?
4
No. If the flow reading is erratic rather than low or high, or you are
experiencing another issue, continue on to “Status of Flow Reading: Erratic”
on page 3-8.
4
Yes. If the flow reading appears too low or too high, troubleshoot using Table
3-4 below.

Question/ Possible Cause Corrective Action
Have the transducers been
placed in the recommended
location on the pipe?
Make sure that the transducers have been mounted in an
acceptable location:
4
Try moving the transducers. Consider straight run
requirements when deciding where they need to be
mounted (see “Straight Run Requirements” on
page 2-5 for more information)
4
Make sure the transducers are mounted side by side,
flush with the pipe
4
Make sure the exterior of the pipe was cleaned prior
to mounting the transducers
See “To Mount the Clamp-On Transducers to the Pipe:” on
page 2-9 for more details.
Have you performed the
suspended particle test to see if
the liquid in the flow is
compatible with Doppler
operation?
See “Suspended Particle Test For Doppler Signals” on
page 3-10.
Have you consulted the Echo
light consideration section?
See “Echo LED Light Considerations” on page 3-9 for
information on whether the Doppler is the right meter for
your application. A transit time meter may work better for
your application if the Echo light continues flashing.
