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 an actuator 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.
Claims15
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;
- 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 an actuator 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 coupler mechanism arranged to transfer movement of the actuator to the indicator.
A system for actuating an indicator assembly in response to a depth change in a liquid that is confined to a container having at least one opening therein for transferring liquid material into and out of the container, comprising:
- a housing mounted in the container opening;
- a float constrained to vertical movement relative to the housing in response to changes in liquid depth in the container;
- actuator means connected to the housing and arranged to move in response to vertical movement of the float;
- coupler means arranged to transfer movement of the actuator means to the indicator assembly.
