Abstract
A system for actuating an indicator in response to a depth change in a liquid that is confined to a container comprises a housing, a float constrained to vertical movement in response to changes in liquid depth in the container and a drive rod arranged to move in response to vertical movement of the float. A flexible coupling is connected to the actuator and arranged to maintain the actuator in a vertical orientation in the liquid when the actuator and the housing are out of vertical alignment, and a coupler mechanism arranged to transfer movement of the actuator to the indicator.

A system for actuating an indicator in response to a depth change in a liquid that is confined to a container, comprising:
- a housing;
- a flexible coupling having a first end and a second end, the first end being connected to the housing, the flexible coupling comprises a flexible shaft having a variable shaft length compensator;
- a lower assembly connected to the second end of the flexible coupling, the lower assembly including a float constrained to vertical movement in response to changes in liquid depth in the container and a drive rod arranged to move in response to vertical movement of the float, the flexible coupling being arranged to maintain the actuator in a vertical orientation in the liquid when the actuator and the housing are out of vertical alignment;
- a pair of parallel rods connected to the housing and arranged to be inserted into the liquid;
- the float being slidably mounted to the rods such that the float is constrained to linear movement lengthwise along the rods;
- and
- a coupler mechanism arranged to transfer movement of the actuator to the indicator.
