Outsider MDT: Accurate Water Metering Made Easier

Outsider MDT Overview
Outsider MDT is a metering data transceiver designed for indoor use with the NMT SingleMag™ and VersaMag™. It enables automated meter reading (AMR) through near real-time data transmission, allowing usage data to be wirelessly sent to the Data Concentrating Access Point (DCAP) or LoRaWAN Gateway for valuable insights into consumption patterns for property stakeholders.
This device supports both vertical and horizontal installations, making it adaptable to various plumbing configurations across residential and commercial properties. With its wire-free design, Outsider MDT simplifies installation, allowing utilities to efficiently monitor water consumption.
Equipped with an AMR radio, Outsider MDT eliminates manual meter readings and helps ensure accurate billing, providing timely insights for effective resource management.
Supports wireless ranges from 1 to over 10 miles, with extended coverage via repeaters (Standard and MAX) or additional gateways (LoRaWAN) for flexible deployment across diverse property layouts.
