Metex StreamSentry – Water Analyzer and Control System

Overview

The MX StreamSentry is a plug-and-play solution for in-line water quality monitoring applications. Easily customizable to meet your specific needs, the StreamSentry offers free real-time data management and tracking of key performance indicators including flow rate, temperature, pH, total dissolved and suspended solids, corrosion, and more! For remote situations, a solar-powered version with cellular data has you covered, while multiple relay outputs allow for immediate control on out-of-spec measurements. Designed for ease of use, each unit ships fully assembled and pressure-tested, for quick installation in pipe sizes between ¾” to 4” and flow rates between 3 – 1100 GPM. Sensors can be accessed and calibrated without having to isolate the main supply or discharge lines, preventing any disruption to your operations.

Common applications include, but are not limited to:

  • Well and potable water quality
  • Sewer discharge permit compliance
  • Stormwater monitoring
  • Industrial processes (closed loops, cooling towers, wastewater, etc.)
  • Agricultural water management
