Have more dtails now.

The frequency is 433.92 Mhz. The receiving end has a generic UHF data
receiver probably same as used everywhere. This then feeds into a PIC
chip (surface mounted). This drives a single digit LCD display. Also has
a dual op amp and a voltage regulator. Transmission interval appears to
be more like every 15 minutes once initialy calibrated. Has three uk
patents GB2318696, GB2302178 and GB2303920, looking these up did not
elucidate much details, 2 are for the sensor syetem bit and the other
for an RF transmitter.

Anyway sounds like no details out there yet, I do like the idea of
dialing own computer and parially the see output from chip.

Thanks everyone now back and talk to my mate who wants to link into a
home automation setup.

Have you considered asking them for the protocol. Not sure how it would
damage them if you used it to connect to an automation system as they still
sell the kit with the tank AND it would look good as a press release.
