摘要： A liquid level controller is shown having a housing with a rear wall. A shaft has a first end which extends through the rear wall to a liquid displacement member located within a liquid containing vessel. A second end of the shaft joins a pair of oppositely extending arms. Each of the oppositely extending arms is rotationally mounted on the housing generally parallel to the rear wall in a bearing. Vertical forces responsive to changes in liquid level act on the displacement member and are transmitted as a force tending to rotate the oppositely extending arms. A lever pivotally mounted to the housing is interconnected with a torque bar which, in turn, connects to the oppositely extending arms of the shaft. A valving assembly is engaged by the lever to provide an output for controlling liquid level within the vessel. The valve assembly includes a pneumatic pilot with a contact point which is engageable by a pin carried on the lever. Movement of the torque bar is transmitted through an adjustment member to the lever pin, whereby movement of the lever actuates the pneumatic pilot.
