For flows between 750 – 1500 GPM, the Williams Fire Model 5 Water Powered Oscillating Monitor is designed to automatically discharge water or foam over a specific design area upon system activation. A water drive wheel connected to a double reduction gearbox drives the oscillating mechanism.
The Model 5 Water Powered Oscillating monitor and body of the oscillating unit are manufactured of brass. The water drive wheel is bronze with bronze supply gate valve. To operate the drive wheel, a small quantity of flow is diverted from the monitor inlet. The monitor requires no external wiring or hydraulic control for operation. The drive wheel design is unique in that it does not require an inlet filter.
This makes the oscillating mechanism highly reliable and less likely to fail. Vertical angle of elevation and horizontal arc of oscillation is field adjustable and can be set and locked in position. The monitor can be set to oscillate over a range of 0°-120° at an adjustable oscillation speed from 0° – 30°/second (0°-24°/second @ 100 psi). The arc of oscillation can be set anywhere within the 360° field of operation. The nozzle elevation range of the unit is between +80° and -40°.
