    • Known devices for determining the filling level of liquefied gases in a cryogenic container are provided with an array of sensors distributed vertically along the volume to be measured, and with a signal transmitter for producing a signal that can be detected by the sensors, as well as with a level indicator. The aim of the invention is to provide, starting from the prior art, a simple and low-maintenance level meter. To this end, the signal transmitter comprises a magnet (11) linked with a floating body (10). Said magnet can be displaced along an array of magnetic field sensors (5) and produces a magnetic field that is detected depending on the filling level (8) by one or more of the magnetic field sensors (5) and is transmitted to the level indicator (6) in the form of a filling level signal.

    • A liquid level control system utilizes a sensor that is attached to a fixed support relative to a liquid container and transmits radio-frequency signals to a remotely located liquid supply system depending upon fluctuations in the liquid level. In the context of a swimming pool, the sensor housing is attached to a sidewall of the pool, at the desired water level. A sensor circuit located within the housing floats at the liquid level, and as changes occur, movement of the floating sensor results in the transmission of signals to either activate or deactivate a supply valve that supplies replacement water to the pool. A small opening located at an upper portion of the sensor housing cooperates with the floating sensor to dampen the motion of the sensor, providing a more accurate reading of the liquid level.

    • Disclosed is a level sensor (161) for sensing level of cooking medium in cooking medium storage means (151) of a cooking apparatus (110). The level sensor (161) includes a tubular housing into which cooking medium may flow from a storage means (151) in which liquid level state is to be sensed; a conductive coil (24) mounted relative to the tubular housing (20); a ferromagnetic float (22) which, when moved into proximity with the coil (24), induces a current to flow therein. The level sensor (161) also includes a resonant detection circuit (24, 26, 28) coupled with the coil (24) such that when current is induced to flow in the coil (24) by movement of the float (22), resonant frequency of the detecting circuit (24, 26, 28) alters. Any frequency alteration outside permissible bounds is detected and provided as a control signal to the cooking apparatus control unit (100). Cooking apparatus (110) including such level sensors and methods of determining level using such level sensors (161) form further aspects of the disclosure.
