[RE-wrenches] SWH data logging

[Karl Schwingel]

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.
