there may be a unit on the market soon from APRS (aprsworld.com) that
is a data logger, and differentail controller. it'll run on grid power
or DC from a pv pump driving panel.
the need right now is for a good reasonably priced (probably pulse
style) flow meter.
no word on the timeline of the product.
vernier also makes some nice little data loggers, but I've no real
information to offer on them.

Thermal wrenches,
We have a customer who wants to log the energy gain of his SHW system.
The only viable option we've found is by Resol (also rebranded by Caleffi)
which includes their top-line controller (~$280) in conjunction with their
data logger, DL-2 ($500). With markup and installation this system will cost
our customer over $1K.
Are there any other AFFORDABLE options out there, that include data logging
to a computer or web interface?
Thanks,
-Kelly
