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
An indication device comprising an elongated fluid chamber containing at least two immiscible fluids, at least one of which has a characteristic physical property different from the other fluid, namely, a liquid driven by an at least one MHD pump for such liquid and an immiscible fluid having a different physical characteristic from the liquid, wherein at least one feature of the liquid contained in the chamber is used as an indicator, which feature the at least one MI-ID pump drives along the chamber either directly or indirectly, via another fluid in the chamber, along adjacent indices of an indicator visible to an observer, the indication device further including a feature location sensor and a feedback controller which cooperate so as to activate the pump to move the feature to a desired location in the chamber in order to indicate to the observer.
