Abstract: A low power consumption leak detection device for a toilet tank includes a water level switch disposed within the toilet tank having a float. The float moves with a water level within the toilet tank from a starting position to a lower position. An electronic circuit is configured to be electrically disconnected from a power source when the float is in the starting position. The electronic circuit is configured to be electrically connected to the power source when the float is in the lower position and activate a timer having a preset time limit, which if reached sends an alarm signal to an alarm indicator. The alarm indicator notifies a resident of a potential water leak problem that can be fixed. The lower power consumption leak detection device only uses power when the water level drops thereby greatly extending the life of the battery and usefulness of the device.

Abstract: An improved fluid level sensor includes a radially magnetized magnet integrated into a float, and a Hall sensor adapted to monitor the magnet field emitted from the magnet. This arrangement provides a continuously variable signal across a range of travel, such that a controller receiving the signal can produce precise fluid level measurements and detect operational states of an associated device based on fluid behavior. In addition, the present fluid level sensor is suitable for use in harsh service environments, both because it is physically resilient to fouling, and because the controller is capable of detecting fouling by sensor behavior. In the context of a steam cooker, the present fluid level sensor can also sense low-water, overfill and fouling conditions, while remaining relatively insensitive to food residue, water scale buildup, corrosion and foaming.

Abstract: A system for monitoring a state, for example a filling state of a container, with a first sensor which in operation produces a measured value, and a second sensor which in operation produces a second, discrete measured value. The first measured value and the second measured value are forwarded to an evaluation unit via a common line.

Abstract: Provided is a liquid level alarm device for a water filter including an alarm assembly and a liquid level detecting device. The liquid level detecting device is electrically connected to the alarm assembly and arranged in a water tank of the water filter. The alarm assembly is arranged on the water tank. The liquid level detecting device is configured to, in condition that a liquid level in the water tank rises to a preset height, send a liquid level warning signal to drive the alarm assembly to send an alarm signal. By arranging the liquid level detecting device in the water tank of the water filter, the liquid level in the water tank is detected by the liquid level detecting device. When the liquid level in the water tank of the water filter reaches the preset height, the liquid level detecting device sends a driving signal to drive the alarm assembly to send an audible and visual alarm signal. When seeing or hearing the audible and visual alarm signal, the user can know that the filter element of the water filter is blocked and fails to operate normally.

Abstract: A transducer for determining the level of liquid within a container includes a mounting head for connection to the container; a senor tube extending from the mounting head; a substrate located in the sensor tube; at least one sensor positioned on the substrate for sensing a level of liquid within the container; and a float constrained to move along the sensor tube. The float has an actuator for changing an electrical state of the sensor to thereby indicate liquid level. At least one damping section having at least one damping beam integrally formed with the substrate is normally in contact with a surface associated with the sensor tube and is movable toward and away from the substrate to dampen forces acting on the transducer and thus on the at least one sensor. An electronic assembly with integral damping sections is also described.

Abstract: Methods, apparatuses, and storage mediums are provided for detecting water shortage for a humidifier. The method includes: obtaining a water level parameter of a water tank; determining a water level state of the water tank according to the water level parameter. When the water level state of the water tank is a water shortage state, energizing a valve connected to a water box so that water can be added to the water tank through the valve. A number of times of energizing the valve is recorded. When the number of times of energizing the valve exceeds a first preset number of times as well as when the water level state of the water tank determined every time after energization of the valve is the water shortage state, confirming that the water box is short of water.
