DESCRIPTION AND SPECIFICATIONS
SECTION 1.0.
DESCRIPTION AND SPECIFICATIONS
1
• COMPLETE SYSTEM INCLUDES sensors, connecting cables, analyzer, and flow controller.
• CONTINUOUS pH CORRECTION eliminates expensive and messy reagents and trouble­some sample conditioning systems.
• MEASURES FREE CHLORINE IN SAMPLES having pH as high as 9.5.
1
• VARIOPOL QUICK-DISCONNECT FITTINGS make replacing sensors easy.
1
In some cases, the sensor can be used in samples having pH as great as 10.0. Consult the factory.
1.1 APPLICATIONS
The FCL free chlorine system is intended for the determination of free chlorine in fresh water. Unlike free chlorine analyzers from other manufacturers, the FCL does not use expensive sample conditioning sys­tems or messy reagents to control pH. Instead, the analyzer automatically compensates for changes in the pH of the sample. The FCL is not intended for the determination of total chlorine or combined chlorine (like monochloramine). Nor, can the FCL be used for the determination of chlorine in seawater.
1.2 FEATURES
The FCL uses a membrane-covered amperometric sensor. A polarizing voltage applied to a platinum cathode behind the membrane destroys any chlorine that diffuses through the membrane, keeping the con­centration of chlorine in the sensor equal to zero. The current generated by the cathode reaction is propor­tional to the rate of diffusion of chlorine through the membrane. Because the concentration of chlorine in the sensor is zero, the diffusion rate and the current are proportional to the concentration of chlorine.
There is a difficulty, however. Amperometric free chlorine sensors measure only hypochlorous acid. Because free chlorine is a pH-dependent mixture of hypochlorous acid and hypochlorite ion, a change in pH will cause the sensor response to change even though the free chlorine level remained constant. Most manufacturers solve the problem by treating the sample with acid, which lowers the pH and converts hypochlorite ion into hypochlorous acid. The
FCL
avoids the expense and inconvenience of
sample
conditioning by measuring the pH and applying a cor-
rection to the raw chlorine sensor signal. The correc­tion is valid between pH 6.0 and 9.5. Below pH 6.0, no correction is needed. For samples having pH between 9.5 and 10.0, consult the factory.
The FCL is available in two options: Model FCL-01 with manual pH correction and Model FCL-02 with continuous pH correction. Choose the FCL-01 if
the
pH varies less than 0.2 or if pH changes are
pre­dictable or seasonal. Choose the FCL-02 if the pH varies more than 0.2. To provide the continuous pH correction, the Model FCL-02 requires a separate pH sensor.
Maintenance is fast and easy. Replacing a membrane requires no special tools or fixtures. A screw cap holds the pre-tensioned membrane in place. Replacing the electrolyte solution takes only minutes.
The FCL includes the easy-to-use Model 54eA
analyz-
er. The analyzer features two fully programmable
4-20 mA analog outputs and three alarm relays. Programming and calibration are simple and intuitive. The large backlit display allows the user to read chlorine at a single glance.
Valves, rotameters, and pressure regulators to control sample flow are things of the past with the Model FCL. A constant head overflow sampler ensures the correct sample flow to the sensors. To eliminate wiring hassles, quick-disconnect Variopol cable is standard.
Stable free chlorine standards do not exist. The chlorine sensor must be calibrated using the results of a laboratory test run on a grab sample.
