ABSTRACT:
A remote visual liquid quantity indicator comprises a flexible cable within a flexible outer sleeve and allows a user to remotely determine the level of a liquid in a container, such as an accumulator without the need for electrical power or a direct line of sight to the container. The flexible cable may be coupled between a reservoir sweeper of the accumulator and an indicator. Changes in the fluid level of the accumulator may provide a linear movement to the flexible cable, which in turn provides a change to the measurement reading of the indicator. The flexible cable/outer sleeve allows for the complex routing scenarios necessary in the congested spaces surrounding aircraft accumulators.
