ABB upgrades AquaMaster EM water flow meter range
13 September 2011
ABB has upgraded its proven AquaMaster electromagnetic water flow meters with an expanded range of power source options, making it ideal for water billing and leakage applications in virtually any location. Based on ABB’s AquaMaster Explorer transmitter, the AquaMaster 3 offers a choice of mains and battery power options, plus an all-new renewable power version which can draw power from either solar or wind-powered energy sources.
A simple dc (6-21V) connection can be hooked up to sources as small as a 5W solar panel or 60W equivalent wind supply. When coupled with its use of super capacitor (SuperCap) energy storage technology, this feature totally eliminates the need for either mains or battery power, making the AquaMaster 3 suitable for use in remote locations.
In mains-power mode, SuperCap maintains continuous measurement and alarms reporting via SMS for up to seven days in the event of a power failure. This is extended to three weeks for the renewable power mode, with the SuperCap also acting to power the meter during the night.
A new development of the battery-only version is the option to specify high powered batteries, which offer an extended operating life of up to ten years in standard applications and improved performance in harsh applications above 45°C. Where the battery is utilised, SuperCap enables the battery to be replaced without loss of logger contents.
