Free Chlorine Measurement As Simple As 1-2-3 With FCA-22 Analyser System

The measurement and control of Free Chlorine has never been easier than with the FCA-22 Analyzer System from Electro-Chemical Devices, Inc. (USA), which features a virtually plumb-and-play design.  This panel-mount analyser system comes factory pre-wired and with assembled flow tubing.

ECD's advanced sensor and controller technologies allow installation and commissioning to be completed in just three easy steps utilising simple tools. Municipal water system and industrial process engineers will find the FCA-22 Analyser precisely measures free residual chlorine while also offering a low cost-of-ownership.  It features a long-lasting sensor that minimises part replacement and technician labor expenses.

The FCA-22 Analyser provides highly reliable on-line continuous free chlorine measurement in a complete systems package. It is designed to monitor free chlorine in drinking water, rinse water, cooling water and other fresh water samples from 0.05 to 20.0 ppm Cl2, 5 to 9 pH and at temperatures from 32 to 122°F (0 to 50°C).  Download our FCA-22 Data Sheet.

The design criteria for ECD’s new sophisticated chlorine sensor were high accuracy with a minimal maintenance requirement. Constant head flow control, automatic pH compensation and a rugged amperometric Cl2 sensor keep maintenance to a minimum with unsurpassed accuracy and performance.

The FCA-22’s constant head flow control device (CFD) maintains the optimum water flow past the sensor over a wide range of incoming sample flow rates from 10 to 80 gallons per hour.   The incorporation of a pH sensor in the FCA-22 provides accurate compensation for samples from 6.5 to 9 pH, which eliminates the need for an expensive pH sample conditioning system.  The Cl2 sensor’s polarographic, gold/silver PFTE membrane construction extends sensor life to reduce operational costs.

With many other free Chlorine sensor technologies, electrolyte replacement is a monthly or bimonthly task that requires the constant purchase of refill kits.  A technician is required to refurbish and re-install the sensor and reconfirm the calibration, which results in unnecessary parts and labor expense that adds up over the complete life of the analyzer.  The new FCA-22’s advanced design extends sensor life to approximately one year.

The FCA-22’s multi-bus controller design enables easy customization of various outputs and control functions. The standard FCA-22 has two SPDT relays and a 4 to 20 mA output for the free chlorine signal, with additional outputs available as an option.
