Continuous on-stream monitoring of cooling tower water. |
摘要 |
<p>The performance of a treating agent added to a body of water employed in a cooling tower is continuously monitored by real-time analysis of a spectral or chemical characteristic of an inert tracer proportioned to the treating agent, said characteristic being indicative of tracer concentration, and converted to a voltage analog. The voltage analog is compared to a monitor value representing par performance and if performance is nonstandard (nonpar) a signal is generated which alters the output of a pump which feeds the dosage of treating agent containing proportioned tracer.</p> |
