 Traditionally RTUs were used in the water industry simply for monitoring of system alarms and 'connection' of tank level data to pump stations for the stopping and starting of pumps. Applications for Kingfisher RTUs in the water industry now include monitoring and control of equipment at pump stations, reservoirs, treatment plants, pipelines, meters, valve stations, dosing points and water quality sites.
Kingfisher RTUs' advanced logic capability allows PID control, accumulation of flow totals, complex calculations and manipulation of system data. Communications flexibility is achieved using a range of media that includes PSTN, leased line, radio, cellular and satellite interfaces. The low power operation allows significant cost savings to be achieved when using RTUs in solar and battery powered applications.
A common application for Kingfisher RTUs is wet well control in waste water pumping stations. The RTU stops and starts the pumps; checks pump availability and rotates pump usage; accumulates pump information such as starts and hours run; and provides advanced alarming on pumps.
In large waste water systems, RTUs are used to manage and balance the flow to the treatment plant to achieve a more constant throughput. This is achieved by analysis of RTU data that includes the storage capacity and inflow rate to dynamically control pump stations, ensuring that plant operations run more efficiently by reducing the effects of morning and afternoon peak periods.
