New AquaMaster 3 offers even greater power to the user

Posted: Monday 7th November 2011

ABB has upgraded its proven AquaMaster electromagnetic water flowmeters 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.

The creation of the renewable power version of the AquaMaster 3 marks a continuation of the high reliability, accuracy and innovation set by its predecessors. 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 energy storage technology, this feature totally eliminates the need for either mains or battery power, making the AquaMaster 3 suitable for use in even the remotest locations.

By using electrostatic energy storage, super capacitors offer a reliable alternative to conventional battery technology. Unlike batteries, which experience a chemical reaction whenever energy is stored or discharged, super capacitors can withstand thousands of charging cycles with no degradation.

In the mains-power mode, the SuperCap technology maintains continuous measurement and alarms reporting via SMS for up to seven days in the event of a power failure. This is expanded to up to three weeks for the renewable power mode, with the SuperCap also acting to power the meter during the night.

A new development in the battery-only version of the AquaMaster 3 is the additional option of high powered batteries, offering an extended operating life of up to 10 years in standard applications and improved performance in harsh applications above 45°C. Where the battery is utilised, the SuperCap enables the battery to be replaced without loss of logger contents.

Installing the AquaMaster 3 is made simple by its use of ABB’s ‘fit and flow’ intelligent installation technology. With this technology, all aspects of an installation are stored within the sensor, including the site settings, calibration factors and any serial numbers usually required during installation, maintenance or replacement. When connected to a transmitter, all of this information is automatically uploaded from the sensor, greatly simplifying the installation and commissioning process.

As a further assurance of a robust metering regime and lifelong accuracy, ABB also offers users its CalMaster2 in-situ verification service for the AquaMaster 3. Performed by an ABB service engineer, this service verifies a meter’s current operational status and also predicts any potential future faults. Users are issued with traditional calibration verification certificate complete with an uncertainty statement.
