Automatic Sewage Regulator
Types of Control

Type A

This arrangement is primarily designed to shut off all flow to the interceptor when flow in the combined sewer reaches a predetermined level.  The float is actuated by the level in the combined sewer through a telltale.  The regulator may also be adjusted so that some flow will pass to the interceptor at all times.

Type B

This arrangement is primarily designed to regulate  the amount of flow in the interceptor when such flow reaches a predetermined level.  The float is actuated by the level in the interceptor through a telltale.

Type C

This arrangement is designed to pass a predetermined amount of flow to the interceptor at all times, regardless of conditions in the combined sewer.  The regulator acts as a governor and the float is actuated by the flow after it has passed through the regulator and before it passes to the interceptor through an orifice plate.  The desired flow may be governed within limits of plus and minus 10 percent.
