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)?


YOu can use one of these, but you will not like the price.

Search for Micromotion. They will be several thousand each.

I work with them often where I work.
Depending on the size you get, you can measure from a gallon every day or
less up to thousands of gallons.

As others mentioned, get a bucket or a gallon milk jug.
