A Microprocessor-Based Controller for the Plugging Factor Monitor

摘要

The Yuma Desalting Test Facility was constructed by the Bureau of Reclamation to provide data to design the proposed Yuma Desalting Plant near Yuma, Ariz. This plant would reduce the salinity of Colorado River water delivered to Mexico. Instrumentation for the test facility includes a measuring device to monitor the plugging factor of the water at various points in the water pretreatment process. The plugging factor indicates the amount of organic and inorganic particulate matter which is suspended in the water. To automate the measurement process, a controller was needed for the measuring device. This report covers the maintenance and operation procedures for this controller. Hardware drawings of the system and flowcharts of the system software are included.
