The WIZARD ARC Controller for liquid chemical day tanks and dry chemical feeders is designed to automatically refill your day tank or hopper from bulk supply when the tank or hopper runs low. Also included in the controller are powerful chemical accountancy features that accurately monitor chemical usage, level and feed rate.A large, easy to grasp HAND-OFF-AUTO (HOA) switch provides operators with an interface to fill the day tank/hopper automatically or manually, or to shut off the transfer operation. The WIZARD ARC Indicator/Controller provides convenience and safety in a single package. Operators can review chemical inventory and consumption as well as replenish supplies with a single instrument. Automated operation minimizes personnel contact with chemical and the chance of failure to refill. Fail safe operation prevents tank/hopper overfilling. A 'MAX DAILY USE' alarm prevents your system from feeding more than a set amount of chemical within a 24 hr. period.
