Messenger-SMB

Product Overview

The Messenger SMB is a packaged system designed to provide a rugged, outdoor monitoring system for remote or unattended facilities. The SMB reports to Antx’ Centurion web-based system for mobile and PC access.

Each SMB system includes:

  • Small weatherproof enclosure with handle for easy carrying,
  • Cables for level sensor, pulsing flow meter, Modbus smart sensors and solar panel,
  • Backup battery and solar charger,
  • Active LTE 4G cellular-based Messenger telemetry unit with external high-gain antenna and GPS,
  • Magnets for mounting to metal surfaces and
  • Pre-configured Centurion web-based monitoring, alarming and remote access system.

The SMB has M12 panel mount connections for:

  • Digital on/off conditions
  • Pulsing flowmeters
  • 4-20ma input (level, pressure, flow, etc)
  • Modbus RTU (flowmeters, water quality, PLCs, etc.)
  • Solar panel or DC input
  • External cell antenna

Typical applications include:

  • Impoundment level monitoring
  • Flow meter monitoring
  • Water quality sondes and sensors (YSI, In-Site, Ott, Global Water, etc.)
  • Remote control of electric pumps, motors, VFDs and soft starters
  • Diesel-driven generators with electronic controls
  • Controllers supported via Modbus include: DynaGen, DeepSea, ComAp, Generac, Basler, Kohler

Capabilities:

  • For level measurement, the SMB is equipped with a 4-20ma analog input that typically is used with a pressure sensor placed in the impoundment of water.
  • For level measurement of brine or produced water, the SMB is equipped with a powered Modbus connection to use with sensors that provide information to adjust the level measurement based on the density of the liquid.
  • For pulsing flow meters, a digital/pulsing input is provided to convert pulses into flow rate, daily flow volume and total job volume.
  • For Modbus flow meters, forward flow and total flow volume are monitored and reported.
