The Wizard 4000 with Auto Refill Control (ARC) from Force Flow provides all the chemical usage and feed rate data that the standard Wizard offers, along with the ability to automatically refill the chemical day tank from a bulk supply. Auto Mode requires no operator input, Semi-Auto Mode requires an operator to initiate fill, and Batch Mode fills a preset amount of water for diluting dry chemicals. It allows operators to remotely monitor the chemical status from a PLC or SCADA system. Up to four day tanks can be independently monitored and refilled using a single unit. 800/893-6723; www.forceflow.com.
