AquaMaster 3 electromagnetic water flowmeter

The AquaMaster 3, the latest addition to the company’s AquaMaster family of electromagnetic water flowmeters, has an expanded range of power-source options, making it suitable for virtually any location. It comes with a choice of mains and battery power options, and a new renewable-power version can draw power from either solar or wind-powered energy sources. A simple 6–21-V d.c. connection can be hooked up to sources as small as a 5-kW solar panel or 60-kW-equivalent wind supply. The AquaMaster 3 uses supercapacitor energy-storage technology (as an alternative to conventional batteries), so it can be used in remote locations. Unlike batteries, which experience a chemical reaction whenever energy is stored or discharged, supercapacitors can withstand thousands of charging cycles with no degradation. This enables the AquaMaster 3 to provide continuous measurement and alarm reporting via SMS for up to seven days in the event of a power failure and up to three weeks when coupled with a renewable power mode.
