Description
ATI’s Model Q46H/64 Dissolved Ozone Monitor provides an economical and reliable measurement system for monitoring and controlling ozone treatment systems. With a variety of outputs including 4-20 mA analog, PID control, three adjustable relays and digital communication, the Q46H/64 is adaptable to any ozone application.
Many drinking water systems add fluoride to their water to help their residents prevent tooth decay. To achieve a fluoride concentration of about 1 PPM, a hydrofluorosilicic acid or sodium fluoride solution is metered into the process at a rate that is proportional to total plant flow. However, flow control problems may result in a loss of chemical feed or over-feed condition. An on-line fluoride monitor can provide reliable control of chemical addition for a consistent fluoride concentration.
ATI’s Model 46H/64 monitors use a polarographic membraned sensor to accurately measure ozone in water. The sensor operates much like a battery, generating current that is nearly proportional to the concentration of zone in solution. An ozone-permeable membrane isolates the sensor from the measured sample and insures that the measurement is interference free.
Two version of the sensor are available, a sensor intended for installation in a flowcell and a sensor intended for submersion applications. Requiring minimal maintenance, sensors are easy to use and easy to maintain. An integral RTD rovides temperature compensation and allows temperature to be displayed and transmitted from the monitor.
Ozone sensors require 2 to4 hours of stabilization time when first installed or after membrane change. ATI offers a battery powered “polarizer” that can be used to stabilize a spare sensor so it is ready to run within a few minuted of installation. Polarizers imply plug into the sensor connector and require no adjustments.

Dissolved ozone sensors require a steady flow of sample across the membrane at the tip of the sensing assembly. A number of options for flowcells, including the standard constant-head overflow system, a sealed flowcell for pressures up to 50 psi and a low volume flowcell where low sample flow is important. A 1½” flow tee is also available for in-line applications with reliable constant flow and pressure conditions.
