Cooling Tower Water Analyzer

Cooling Tower Water Analyzer This Analyzer system provides continuous monitoring of cooling water quality. The cooling water can be improved by blowdown and makeup to decrease percent solids. Conductivity is an indicator of solids concentration. Typical conductivity targets for this application range from 1500 to 4000 micro siemen per centimeter squared.

The system consists of a Foxboro 871 FT Flow-through conductivity sensor and redundant 871-3pH sensors with 316 stainless steel flow chambers. Complete sensor and transmitter diagnostics are provided by Foxboro 870I loop powered transmitters. Advantages of the 871FT Flow-through sensor are the ability to be calibrated in line and the replaceable RTD. The 871-3F pH sensor with ruggidized flat glass construction provides durable measurement of pH in the range of 2 to 12. The system is winterized for operation at -20° F with an O'Brien Vipak enclosure and explosion proof heater. Power connection kits are provided to power tracing for sample lines.

The system can also be configured to measure Bromine used as an algaecide by using an 871A ORP (Oxidation Reduction Potential ) sensor in place of one of the pH sensors. The target range for bromine is typically 350 to 400 mV.
