LIQUID LEVEL RESERVOIR CONTROL |
摘要 |
<p>A device for sensing and controlling liquid level in a reservoir container. The device includes a sensing element in the form of a displacer which enters the liquid through the surface and displaces a predetermined volume. The displacer is located in a surge tank into which the liquid is initially fed and from which it is supplied to the reservoir. The displacer is mounted on an arm of a lever, the displacer being counterbalanced to respond to a liquid level in the surge tank. The lever carries a switch actuating mechanism which is moved in response to a change in the liquid level in the surge tank and which controls actuation of a single acting piston pump air motor to supply liquid to the surge tank.</p> |
