I'm finding the Aqualarm raw water flow alarm to be a much better idea
in theory than practice.


Considering the rest of the thread, I'm inclined to agree with you.

Our high-temp alarm has been tripped three times in 12+ years and 1500
hours. Once, a brand new impeller failed; the next was when a BIG seed
plugged the intake; the third was 55 minutes after firewalling to the
1-hour maximum RPMs. The Aqualarm wouldn't have caught that last.

For a few minutes' warning every 700 hours or so, I'm not sure that
another failure-prone gadget is worth it.

If an alarm goes off, you stop and figure out what's wrong. Adding an
alarm with such a high false-positive rate seems counter-productive.
