Abstract
An apparatus and method are provided that enable the control of a screening operation based on a calculated screen blockage percentage and the velocity throughput of the screen. The apparatus includes an upstream level detector, a downstream level detector and a flow determining device which determines the volumetric flow through the screen. The apparatus may further include a blockage determination unit which determines the percent screen blockage based on the flow level upstream of the screen, the flow level downstream of the screen and the volumetric flow.
Claims7
A method of controlling a screen disposed in a flow within a channel, the method comprising:
- determining an upstream level of the flow in the channel upstream of the screen and a downstream level of flow in the channel downstream of the screen;
- and
- determining a volumetric flow in the channel.
