 AquaMetro / Integra water meter "TOPAS ES KR"
 Models TOPAS ES KR 95077 95056 95345 95490 95373 95059 95065 95068 95071 95074 should be compatible. Only 95059 in one configuration tested.
 Identifies itself with Manufacturer "AMT" and Version "f1"
 Product leaflet and observation says the following values are sent:
 Current total volume
 Total volume at end of year-period day (that means: current total volume - total volume at end of year-period day = current year-periods volume up until now)
 Total backward volume on end of year-period day or total backward volume in current year-period. Backward volume remains untested (luckily only 0 values encountered).
 Date of end of last year-period day
 Total volume at end of last month-period dateTime
 DateTime of end of last month-period
 Current flow rate
 Battery life (days left)
 Water temperature
