The FCX80 is a panel mounted, ready to use Free Chlorine Analyzer intended for hazardous locations. It is designed to monitor free chlorine in drinking water, rinse water, cooling water or other freshwater samples from 0.05 – 20 ppm chlorine as the standard range or 0.01 - 5.00 ppm with the low range sensor. The FC80 is compliant with EPA
method 334.0 for measuring drinking water. The FCX80 features a plug and play design that incorporates a constant head flow control device, a pH sensor, a chlorine sensor and the X80 analyzer/ transmitter conveniently mounted on a panel. Connect the sample and drain lines, connect the power and outputs and it is ready to use. Calibration is accomplished by DPD comparison. Free chlorine exists in solution as a pH dependent
ratio of hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10). The Free Chlorine Sensor measures only the hypochlorous acid component of the free chlorine and the analyzer calculates the balance using either the measured pH or a user defined fixed value. The use of the pH sensor provides accurate compensation for samples between pH 6 and pH 9 elimina.ng the need for expensive sample conditioning systems to
control the pH of the solution. The X80 is 24 VDC powered and allows either parameter to be graphically displayed with user defined Line, Bar or Guage style graphs. The
standard configuration has (2) 4-20mA outputs, (3) alarm relays and MODBUS RTU.
Amperometric chlorine sensors are flow sensitive, the minimum required flow by the sensor is 0.5/sec, above this value the output is virtually flow independent. A “Constant head” Flow control Device (CFD) maintains the optimum flow past the
sensor over a wide range of incoming sample flow rates. The minimum flow required for the CFD is 10 gal/hr. and the maximum flow is 80 gal/hr. with the sample going to drain at atmospheric pressure. Hazardous Locations - Refer to X80 Transmitter Data Sheets for ATEX or IECEx or FM approvals and hazardous location information.
