Quick Guide on Getting Started
M3 Sensor & Digi Gateway
Introduction
The Massa Model M3 or M3is Wireless Ultrasonic Sensors used in combination with a Digi ConnectPort X4 Gateway
(or X2) is a solution to non-contact wireless tank level monitoring. This document will guide you to quickly get the
devices integrated and evaluated in your application. For detailed information, see the M3 Sensor Users Guide.
Normal Operating Mode
The basic operating mode is for the M3 Sensor to obtain range (to liquid level surface), temperature and other
information and pack it in a status message then send this message (upon waking up) automatically to the gateway.
The gateway will then push the message to the iDigi Cloud server. When evaluating the application for the first
time, it may be set up to save the status information to a file in the gateway without a cloud server so you can
validate tank level reports.
Overview of Sensor
Sensors supplied from the factory will allow association to any gateway, but with all its settings disabled for
automated messaging. The minimum settings required for tank level measurement and automatic outgoing
messaging to be enabled includes; the sleep time, the awake time (defaulted to 31 sec), and the outgoing message
type. Another noteworthy sensor feature is its ability to obtain diagnostic data (ultrasonic waveforms) that can be
used to evaluate the mounting location (and any issues) and general performance. It is strongly recommended that
each new application (tank model) obtain diagnostic waveforms in an empty or near empty tank. Sensor settings
could require custom sensitivity values and these waveforms will allow you to determine what is best required for
your specific tank. Once an application has been established, it is not necessary to obtain diagnostic waveforms for
the same tank (and mounting location). In general, normal settings will work in most applications. Typical sensor
settings for long battery life have Sleep setting between 1 to 12 hours with the Awake setting at 30 seconds.
Overview of Gateway
The X4 or X2 Gateway details in this guide will only address the use of the Ethernet port and not a cellular
configured X4 gateway (option). You may be required to upgrade gateway firmware and possibly gateway XBee
settings. Massa Products provides python code to allow the sensor’s settings to be easily configured, store sensor
status information within the gateway, store diagnostic waveform data within the gateway, and sending automated
messages to iDigi Cloud server. Up to 10 sensors can be associated to a single gateway but additional sensors can
be added with a Digi Wall Router. For detailed information, see the M3 Sensor Users Guide.
