TELEMETRY SYSTEM FOR WATER AND ENERGY MONITORING

A water quality monitor computer (10) repeatedly accesses transducers (12) which monitor physical properties of a water system, such as total dissolved solids, pH, and the like. The water quality monitor computer determines from the monitored water conditions when bleeding or the addition of water treatment chemicals is required. An energy and water management computer (20) periodically accesses the water quality computer and operates valves and pumps (22) to bleed the system or add chemicals, as is appropriate. The management computer further monitors the quantity of chemical supplies on hand with chemical inventory transducers (24), the amount of electrical energy consumed with kilowatt transducer (28) and the like. The energy and water management computer controls energy usage and stores energy and chemical consumption data in a memory (40). A polling station (B) selectively polls one or more of the remote stations to change the energy or water management programs or to receive data and water system physical property data therefrom. One of the polling stations includes a central computer (250) which polls each remote station daily. The central computer causes a printer ( 254) to generate daily reports indicating abnormal conditions at each remote station and to generate shipping orders and invoices for replacement chemicals as replacement becomes necessary. The central polling computer also generates a monthly report of energy and chemical consumption, water treatment system physical property data, energy savings, and the like.
