In August 1996, Stolt Sea Farms installed a Campbell Scientific monitoring and control system at its recirculating facility in Laguna, California. The system monitors dissolved oxygen levels, water temperature, and total dissolved gases and, based on those measurements, automatically controls solenoid values for oxygen control. The CSI system includes a CR10X, a multiplexer and three relay devices. The system constantly monitors the water quality of tanks used to grow sturgeon, and consequently produce caviar. Water quality data from each of the 12 tanks is sent to a base station PC.
