Ultrasonic Echo Scale Level Sensor

Global Treat supplies ultrasonic echo scales used for monitoring sodium hypochlorite, fluoride, caustic, and other chemical stored bulk tanks at water and wastewater treatment plants. The echo scale sends out bursts of ultrasonic waves to determine the chemical level reamaining in the tank.


  • Safe to use stand alone or with indicators
  • Efficient software for quick set-up and calibration
  • Integral level vials insure proper sensor alignment
