AURIGA DN15/20

Single-Jet Meter

Application

AURIGA DN15/20 is a single-jet water meter designed for measuring cold water in main metering market. Robust, it is particularly suitable for demanding installation conditions and sediment laden waters.
Developed within the framework of the MID, AURIGA complies with the European regulations and holds sanitary conformity certificates.
Modular, AURIGA can be fitted at any time with an IZAR clip-on module converting it into a communicating meter ready for mobile reading (walk-by, drive-by, passive drive-by) or fixed network reading (radio/wired).
