PRELIMINARY
Introduction
Massa Products Corporation manufactures a family of Model M3 Wireless Ultrasonic Tank Level
Sensors for use in tanks of different sizes. The M3/150 Sensors are designed for use in short tanks
and have an operating range of 4 inches to 8 feet; the M3/95 Sensor are designed for medium sized
tanks and have an operating range of 12 inches to 13 feet; and the M3/50 Sensors are designed for tall
tanks and have a range of 14 inches to 35 feet. All of the M3 Sensors operate in conjunction with
Gateways manufactured by Digi International to provide the wireless connection between the
sensors and the central computer that is monitoring the liquid levels in the tanks.
The Massa M3 Wireless Ultrasonic Tank Level Evaluation Kit allows an M3 Wireless Sensor to be
installed into a tank and then be quickly connected to a Digi Gateway in order to easily evaluate the
effectiveness of the system to provide the tank level monitoring solution for that particular tank.
The Massa M3 Sensors and the Digi Gateway establish the wireless path and to obtain data such as
tank levels directly through a communication port of a PC. To extend battery life, the M3 Sensors
normally enter a Sleep Mode when they not communicating with the gateway or collecting data. The
sensors supplied with the Evaluation Kit are preprogrammed to always be awake and do not enter the
Sleep Mode.
Many tank level monitoring solutions may require utilizing an Ethernet connection between the Digi
Gateways and the monitoring computer. This is beyond the scope of this Instruction Guide or the
Evaluation Kit, but such a solution does exist, as described in the overview on Page 10.
The Massa M3 Wireless Tank Level Sensor Evaluation Kit includes:
1) The Massa M3 Wireless Ultrasonic Level Sensor or Sensors ordered with the Kit, with a
2” NPS nut and a 2” gasket.
2) Digi International X4 Gateway (p/n X4-Z11-E-A, Zigbee to Ethernet) preconfigured for Massa’s
M3 Software, and a power supply.
3) A USB to Serial Converter (USConverters.com p/n UT8801).
4) A Null Modem Cable (Digikey p/n AE9879-ND).
5) A Compact Disk containing: a) M3 Application Software, USB Converter Drivers, Digi Device
Discovery Software, and a copy of this Instruction Guide.
6) Three Energizer L91 batteries.
7) An Ethernet Cable for future use with Digi Discovery Software (not used with this Instruction
Guide).
