In one embodiment, four oil levels, including an overfill oil level and an excessively low oil level may be detected. The sensor is referred to as an integrated oil condition and level sensor as multiple sensing functions are integrated into one sensor. | ||||||
| 83 | Collapsible liquid level measurement device with attachment | US11801433 | 2007-06-19 | US20070234798A1 | 2007-10-11 | William Fling; John Fling |
| A liquid level measuring device includes an elongate handle and an elongate frame arranged in telescoping relationship. The frame is movable between a collapsed position for storage and an extended position for usage. A float is movable lengthwise along the elongate frame. A control rod extends lengthwise in the elongate frame and through a passage in the float. The control rod controls movement of the float relative to the elongate frame. An actuator actuates the control arm to move the float from the locked position to the unlocked position in response to a downward pressure between a lower end of the elongate frame and a bottom surface of the container so that the float is free to seek the liquid level in the container and to move the float from the unlocked position back to the locked position when the downward pressure is released. | ||||||
| 84 | Liquid level sensing system utilizing a capillary tube | US10452399 | 2003-06-02 | US20030221485A1 | 2003-12-04 | Ikuo Toki |
| An upright capillary tube is located at a position in a liquid container such that its lower end can be reached by the surface of the liquid level in the container as the liquid level rises and falls with changes in the amount of liquid in the container. A thermal sensor, e.g., a thermistor is provided on the capillary tube. As the liquid level rises and reaches the lower end of the capillary tube, the liquid rises in the tube due to surface tension. As the liquid in the capillary tube reaches the location of the thermal sensor, the sensor responds to a temperature change to detect the liquid level. The capillary sensing system can be miniaturized and is capable of superior sensitivity. | ||||||

| 89 | Method and apparatus for determining whether a liquid in a reservoir is above a certain level | US375526 | 1989-07-05 | US4991434A | 1991-02-12 | A. Ray Snow |
| Apparatus for determining whether a liquid in a liquid reservoir is above a certain level includes suction means operable by a user to create suction when the user desires to determine if the liquid in the reservoir is above the certain level, a conduit extending from the suction means and adapted to be positioned in the reservoir so that a passage in the conduit which communicates with the suction created by the suction means opens into the reservoir above the liquid therein when the liquid is below the certain level, and indicator for indicating whether or not the passage in the conduit is opening into the reservoir above the liquid therein. The indication that the liquid is above the certain level is given by either observing that liquid is being drawn into the passage or that the passage opening is closed. This may be done by observing the liquid itself in the passage or an indicating reservoir, or observing the operation of the suction means which given an indication of flow into the passage. The apparatus may be used to replace the normal dipstick used to measure liquid levels, such as oil level in an automobile engine. | ||||||
| 90 | Remote indicating dip stick | US253226 | 1988-10-04 | US4881486A | 1989-11-21 | William M. Willis |
| A manually operable fluid level indicator as illustrated for indicating at a location remote from a reservoir whether the fluid level in the reservoir has fallen below a predetermined level. A hollow dip stick having an aperture through a side wall of a lower end thereof depends into the reservoir and is normally covered by fluid within the reservoir. An indicator housing has chamber communicating with the interior of the dip stick and has a piston moveable therein by a friction drive connection with a manually moveable plunger. On moving the plunger outwardly of the housing, the piston remains stationary if a vacuum condition exists in the conduit communicating between the dip stick and housing. If the fluid level falls below the orifice and allows air or gas to enter the conduit running to the chamber of the housing, the piston will move with the plunger when the latter is pulled outwardly of the housing and the movement of the piston is visually observed to indicate a low fluid level. | ||||||
| 91 | Adjustable liquid level indicator | US87775 | 1987-08-21 | US4831877A | 1989-05-23 | A. Ray Snow |
| In a device for indicating the level of a liquid in a reservoir of the type which has a liquid receiving area to be positioned partially within the liquid in the reservoir, a liquid confinement tube within the liquid receiving area which may be moved from a liquid unconfining position to a liquid confining position when it is desired to measure the level of the liquid in the reservoir, a piston within the liquid confinement tube coupled to an indicator located outside the reservoir such that movement of the indicator causes movement of the piston within the confinement tube, the amount of movement of the piston and indicator indicating the level of fluid within the reservoir, and a spacer tube determining the length between the liquid receiving area and the indicator, the improvement of making the device adjustable over a range of lengths. To make the device adjustable, the spacer tube is length adjustable and may include telescoping tubes, and the coupling between the piston and indicator is also length adjustable, the coupling being released while adjustment of the spacer tube takes place. It is also preferable to secure the confinement means in unconfining position during the adjustment of the device. When the device replaces a dipstick in a liquid reservoir, the invention includes a method of adjusting the length of the device by aligning portions of the device with corresponding portions of the dipstick. | ||||||

| A sensing device for determining the amount of liquid in an oil crankcase of a vehicle. A hollow dipstick, closed at one end and having a metering hole therein, is inserted into the crankcase of a car. The other end of the dipstick is connected by flexible tubing to a suction diaphragm and sensing diaphragm in a sensing module. The suction bellows and sensing diaphragm are linked together and to the dipstick by branches of a T-tubing. An opposed end of the suction diaphragm is connected to a piston of a solenoid. The sensing diaphragm is mounted to move in response to the amount of oil suctioned into the dipstick. An electrical circuit is formed between a push button, a solenoid, ground, and the car battery, such that, when the push button is closed, the solenoid becomes excited, drawing in the piston to thereby move the suction diaphragm. Movement of the suction diaphragm draws oil into the dipstick. An electrical current is coupled to the sensing diaphragm to indicate if oil is drawn up or samples in the dipstick. | ||||||

| Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on echo times of an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. Engine power is limited differently based on distinct coolant level states determined based on a change in level of coolant in the reservoir over a duration. | ||||||
