An exterior gauge component is used to indicate a tank liquid level based on a rotational orientation of a tank magnet at a gauge head. The exterior gauge component includes a multi-track rotary encoder wheel and an optical sensor configured for reading an output of the multi-track rotary encoder wheel. The multi-track rotary encoder wheel is configured to rotate with rotation of the tank magnet such that specific ranges of rotational orientation of the tank magnet each corresponds to a specific output of the multi-track rotary encoder wheel. Each track represents a binary bit of the output read by the optical sensor. An adapter plate mounts a housing of the exterior gauge component to the gauge head and has an opening therethrough. A proximal end portion of the housing including magnets extends through the opening, and is detachable from the housing and attachable to a threaded adapter for mounting to a threaded opening of a tank.

A system (10) includes a support structure (20) associable with a bottom wall (BW) of a washing tub (WT) of a washing machine (WM). The system further includes a container body (22) having a receptacle (14) configured for receiving a quantity of washing agent. The container body (22) has an opening (24) leading into the receptacle (14). The container body (22) is mountable on the support structure (20) in the washing tub (WT). The container body (22) is configured for being reversibly brought by a user into a retracted condition and an extracted condition. In the retracted condition, the container body (22) is inserted in the support structure (20). In the extracted condition, the container body (22) is removed and separate from the support structure (20). The system (10) includes a closure element (16) configured for closing the opening (24).

A liquid level detection device is provided with a fixed body and a rotating body, and includes a float floating and an arm. The arm has an insertion section to be inserted into the rotating body and an extending section extending linearly and bent with respect to the insertion section. The rotating body has an insertion hole in which the insertion section of the arm is inserted in an insertion direction and a holding section having a receiving opening which receives the extending section and holding the extending section received by the receiving opening. The fixed body has a guide section covering the extending portion in a part of a region between a portion held by the holding section and a portion connected to the float within a rotatable angular range of the arm. The guide section is provided with a passing section used to dispose the part of the extending section inside the guide section.

The present invention relates to a fluid level sensor-attached motor pump for a washer fluid, in which a fluid level sensor for detecting the remaining amount of a washer fluid stored in a washer fluid reservoir and outputting a detection signal is integrally mounted to a motor pump for a washer fluid so that an operator can check the remaining amount of the washer fluid through a dashboard of a vehicle and thus can replenish an insufficient washer fluid, in which the fluid level sensor is integrally mounted to the motor pump for a washer fluid to solve a problem in that the motor pump and the fluid level sensor are separately wiring-connected to the washer fluid reservoir to thereby deteriorate workability of wiring so that workability of wiring can be increased and the wiring can be simplified to reduce a defective proportion, in which the motor pump for a washer fluid and the fluid level sensor are integrally manufactured so that the manufacturing cost can be reduced, and in which the fluid level sensor for detecting the remaining amount of a washer fluid and outputting a detection signal is manufactured by selecting any one of a combination of a magnet and a Hall sensor, a combination of a magnet and a reed switch, and a combination of a Hall sensor and a buoyancy device mounted with a magnet so that the improvement in performance can be achieved through the use of a magnetic Hall sensor having reliability.

A fluid level monitor incorporated into a fuel tank. A sensor module is adapted to being mounted to an exterior of the tank. A tube extends from the module within the tank and secures a housing at an interior location. The housing has a gear assembly, a float arm pivotally secures to the gear assembly and, in response to changes in a fluid level of the tank, causes the gear assembly to rotate a drive rod extending within the tube. A coupler forms a portion of the sensor module and is secured to an upper end of the drive rod. Rotation of the coupler relative to a PCB integrated into the sensor module produces an inductive signal indicative of the amount of displacement of the float and, consequently, the level of the fluid within the tank.

In a liquid level detector, a first clearance may expand as at least one of a rotator and a supporter swells with a target liquid. The first clearance may be a smaller one of an inner clearance between an inner circumference side of a first guide rail and an inner circumference portion and an outer clearance between an outer circumference side of the first guide rail and the outer circumference portion, in a state where the rotator and the supporter are not swelled with the target liquid. A second clearance may contract to become smaller than the first clearance as at least one of the rotator and the supporter swells with the target liquid. The second clearance may be a larger one of the inner clearance and the outer clearance in the state where the rotator and the supporter are not swelled with the target liquid.
