Sensor & Flowcell Options

 Dissolved Ozone sensors require a steady flow of sample across the membrane at the tip of the sensing assembly. ATI offers 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 1-½” flow tee is also available for in-line applications with reliable constant flow and pressure conditions. For simplicity of installation, complete flow control assemblies are available.

Sealed Flowcell

The sealed flowcell allows for a controlled flow of water that can then be pushed under slight pressure to a drain location.  Water flow must be well controlled externally to a flowrate of about 400 cc/min.  Variable flowrate or pressure will cause unstable readings in the sealed flowcell.  A special flow control element can be purchased ahead of this device.  It is part number 55-0048.

Slight pressure, up to 2 PSI is acceptable on the cell to allow water to drain to a remote location through tubing.

 Constant Head Flowcell

The dissolved ozone sensor will provide the best performance when used with the constant-head flowcell.  When monitoring ozone levels below 0.5 ppm this method should always be used.  Water pressure on the sensor and water flow are automatically controlled via the gravity flow chambers in the flowcell.  Water flows of 400 - 500 cc/min will be used.

Low-Flow Flowcell

Low-flow sensor flowcell is used to reduce the amount of water used for ozone detection in water. This is a great option for applications where low water flow rates are required. Sample water flow rates of 150 – 300 cc/min can be used with the low-flow flowcell.

Passages in the low-flow flowcell are very small, therefore, clean water is required. Flow rate can be measured and controlled by a rotometer installed on the inlet side of the flowcell. Water flow should not vary more than 5 cc/min.

Flowcell Sensor

The Flowcell Sensor is used for each of the flowcell systems shown above. There are threads on the sensor body that allow the sensor to thread into the low-flow sensor flowcell and the sealed flowcell. The long smooth end will fit snugly in the constant-head flowcell and seal with o-ring seals integrated into the constant-head flowcell.

Submersion Sensor

For submersible applications we offer the submersion sensor. This sensor can be dropped into a tank of water for ozone measurements in water. This sensor could also be mounted into the side of a tank permanently.

Ensure no more than 2-3 PSI of water present is pressure on the sensor at any time. Water pressure must also be consistent for accurate measurements of ozone in water.

 

  

 

Calibration

The q46H Ozone Sensors must be calibrated on-site with the customers' water in process. As pressure and water flow will affect the calibration it is important to perform the calibration in the specific process the sensor will be used to measure ozone in.

Calibration frequency will depend upon ozone concentration in the water and water quality. Higher dissolved ozone levels will consume the electrolyte solution and membrane quality quicker than low levels of ozone. At ozone levels below 2.0 ppm we find the q46H can maintain stable readings for 6-months at a time between calibrations. However, at ozone levels greater than 20 ppm calibration should be performed at least monthly and ozone levels greater than 100 ppm will require weekly or even daily calibration.

A bottle of electrolyte solution and a pack of 10 membranes is shipped with each q46H Dissolved Ozone Meter.

Calibration should be performed with a colorimetric dissolved ozone test kit. Below are a few kits we suggest and the potential applications for each.

 

I-2022 SAM Dissolved Ozone Meter

 

Best for low level detection of ozone, below 0.75 ppm

 

I-2022 Dissolved ozone test kit for calibration

 

 I-2019 SAM Dissolved Ozone Meter

 

Best for high level detection of ozone, direct read to 5.0 ppm
