ABSTRACT:
A control system and method of controlling the cycling of water in a cooling tower system having a course of make-up water of variable conductivity.
The control system apparatus includes respective probes for sensing tower water conductivity and make-up water conductivity. The probes provide signals to a controller unit. Desired cooling system water conductivity parameters an input into the controller unit. The controller unit serves to proportionately adjust the trip point at which dumping of the cooling tower water occurs based upon the sensed water conductivities and the input parameters to maintain a predetermined Langelier's number(s). Means are provided to display system conditions and to effect calibrations of the system.
The method entails establishing an indexing factor based upon the cooling water parameters and the desired Langelier's number(s) and using that indexing factor for adjusting the trip point.
