Abstract
An indication device is provided. The indication device includes an elongated fluid chamber containing at least one electrically conductive liquid driven by a pump for conductive liquids and an immiscible, relatively non-conductive fluid. At least one segment of at least one fluid is used as an indicator. This segment is driven by the pump along adjacent indices of an indicator visible to an observer using a meniscus location sensor and a feedback controller so as to e.g indicate a quantity to the observer.
