I'd place one of these high tech measuring devices under the
end of the hose, and it should provide accurate data logging
capability.

I have a dehumidifier with pump that drains via a small
plastic tubing
(about 5mm OD).
I'd like to monitor its performance by measuring how much
water flows
through the tubing.
This should be cumulative. E.g. after one day the meter may
indicate 1
gallon, after 2 days it may say 2 gallons, etc.

Is there a meter to do this? What is it called (so I can
search for it)?
