Turbidity, Suspended Solids & Color Monitors

Rugged, reliable monitors to control critical liquid processes

The Monitek product line consists of rugged and reliable monitors for in-line process turbidity, suspended solids and color. Our in-line sensors monitor in real-time, eliminating lag time and periodic sampling. Monitek monitors are installed in the chemical, petrochemical, oil & refinery, beer, food & beverage, biotech, and other markets. Monitek offers both Optical and Acoustical sensor technologies to meet our customer's monitoring requirements. The monitors are a two-component system consisting of a transmitter and a sensor. The Messenger Transmitter is used for all of our optical sensors and can be configured for multiple sensors and applications.

MoniTurb In-Line Turbidity Sensors
  • Forward scatter and/or side scatter techniques
  • Low range concentrations from 0.02 to 500ppm
  • Filter breakthrough, contamination alarm, process monitoring, quality control, chemical additives control applications
  • Turbidity measurement is not affected by process color changes
Monispec A Suspended Solids Sensors

  • Color avoidance, removal and addition in liquids

Work where optical sensors fail

The in-line monitor utilizes a focused acoustic transducer that provides solids measurements independent of the liquid's color, opacity and density. These acoustic “particle” monitors are used in monitoring oil in water, opaque liquids, optically sensitive liquids and applications where fouling of optical sensors require excessive maintenance.
