Yes, it should work fine - at least on mine the dial of the meter with a magnet on never really moved that fast, so you could get away with keeping the magnetometer running at it's default 0.63 sec period, and with that it's ~8uA so you'd hope the Puck would be able to run for 6 months reasonably easily, possibly more if you're careful with the code.
