MADDALENA ELECTO MVM

ElecTo MVM is a rotary piston meter for domestic water, featuring an innovative multiprotocol radio electronic register. Robust, durable, suitable for the most challenging environments and types of installation. Its low starting flow rate and its wide measuring range provide excellent consumption accounting. Its large LCD display makes it very easy to read, while providing additional information to both users and operators. ElecTo MVM offers the maximum short and long distance data communication flexibility, and can be used with both mobile and fixed reading systems.
