FlowPulse M-Bus is a static sensor designed to integrate Maddalena MVM, MVM PLUS C and WMAP EVO
water meters into remote reading systems based on the M-Bus protocol. Equipped with a microprocessor and an inductive electronic sensor, it transmits data to a standard M-Bus master compliant with EN 13757 via a two-wire, polarity-independent connection. The device detects the flow direction and any removal from the meter, without affecting its metrological performance. IP68 protection, environmental class C and electromagnetic class E2 make it suitable even for the most demanding technical applications. It can be retrofitted on prepared meters, simplifying the upgrade and retrofit of existing systems.
