Analyzer System Simplifies Free Chlorine Measurement

Feb. 11, 2014
The chlorine sensor was designed to minimize maintenance

The measurement and control of free chlorine (Cl2) is simplified with the FCA-22 Analyzer System from Electro-Chemical Devices Inc., which features a plumb-and-play design. This panel-mount analyzer system comes factory pre-wired and with assembled flow tubing. 

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

The FCA-22 Analyzer provides reliable online 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 freshwater 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).

The design criteria for ECD’s new 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 accuracy and performance. 

The FCA-22’s constant head flow control device maintains the optimum water flow past the sensor over a range of incoming sample flow rates from 10 to 80 gal 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.
