Sold by ConnectM2M Ltd
Description
The Metermade® N1 Meter Interface Unit (MIU) is an ultra-low power device, designed to operate in the field for up to ten years on a single set of batteries (based on one report per day). It’s housing meets the IP68 rating, permitting direct installation onto a flow meter and is capable of surviving submersion to a depth of four metres for four days.
The Metermade® N1 is the lowest cost option to provide highly reliable billing revenue data, directly to a host database using the industry standard DNP3 or FTP protocol. Remote configuration and device management is supported via leading industry SCADA applications, remote firmware download capability is provided via FTP file transfer.
The N1 is equipped with two (2) digital inputs and provides Forward/Reverse/Nett Totalisers and instantaneous flow calculation as standard. A ‘magnetic swipe’ function is provided to allow on-demand meter reads and data updates by field personnel.
The MIU configuration supports bulk editing/generation permitting high volume configuration and deployment.
