How about the Digiflow 8000T? Search eBay for "Digiflow". It's flow
rate is down at 0.3 gpm. About $42 with shipping on eBay.

I have no connection with this product or vendor, but I have been
mildly interested myself in such an item.

Hi

I would like to install / build a meter that would display the amount
of water I have taken from my water tank(s). There is no access to the
tank(s), installing level senders would be difficult.

I am aware of the WaterWatch. It would suffice but the literature says
the minimum water flow required is ~ 1.6 Gallons Per Minute. I don't
think it would record small demands i.e. brushing one's teeth.
Although it would be good for measuring the amount of water added to
the tanks.

I would prefer a system with a small in-line sensor sending pulses? to
a meter (LED ? LCD?) 10' away.

Any suggestions

If you have a positive displacement water pump and you know its
displacement, then you can count its revolutions.
