Carl,
Thanks for the info. Is data logging/collection possible with the Metrima

Nik,
Thanks for the info. I was just about to ask if anyone has used the
Heliodyne Delta T-Pro
Where did you source it from? Gro has given me an expected price of ~$300
(but don't have 'em). The cost of the digital flow meter/temp gauge is on
top of that. Is the digital flow meter necessary, o

The new Delta-T Pro controllers from Heliodyne have built-in networking
capability (WiFi or Ethernet.) Retail is around $500.

I have one system up and running with the WiFi model for about 4 months
now. No problem
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.

are from ABB (similar to the Metrima in concept). I feel sure Lakeland is

at the ASES solar conference last summer in CLeveland.

I have installed several of the Metrima BTU/KWH meters for SHW. The kit
comes with a flowmeter, temperature sensors and wells (hot and cold), and a
calculator, nicely integrated. These are utility grade meters and more
economical than the hardware you mentioned(dealer price $425). Check
