This invention relates to a device and method for measuring the depth of water and sediment deposition in pipes, channels, overland flows and tidal beaches. Sediment deposition may be detrimental to flood control in sewer systems. The invention is specifically concerned with measuring an electrical property such as the conductivity or capacitance in different mediums and therefore quantifying the depths of the different mediums. The measurement of an electrical property such as conductance or capacitance of the medium may also indicate the nature of the medium such as sediment structure, water salinity, and the presence of pollutants. The device includes an array of elongate, substantially mutually parallel electrodes each having a predetermined length, the lengths being incremented stepwise from a shortest electrode to a longest electrode. The device includes electronic circuitry to apply a potential difference across selected pairs of electrodes and to measure a resulting electrical property between each selected pair of electrodes, the measured electrical property providing an indication of a submersion depth of the pair of electrodes in the at least one medium.

A water level sensor device of a fuel filter may include a printed circuit board and a water level sensor composed of electrically conductive plastic. The water level sensor may be coupled to the printed circuit board via an electrically conductive metal element. The metal element may be coupled to the water level sensor via a press-fit assembly. The metal element may include a sharp-edged fastening contour configured to tear open the plastic of the water level sensor when the metal element is pressed against the water level sensor.

A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.

A water sensor for a fuel filtration apparatus includes a main body with at least one electrical contact disposed proximate the first end of the main body. The electrical contact(s) is operatively connectable to an electronic control unit. Multiple sensor contacts are disposed proximate a second end of the main body. The sensor contacts are configured to detect multiple water levels and provide an output on each water level detected. The electrical contact is configured to send the output to an electronic control unit. The water level information provided by the water sensor can be tracked by a control device to determine if the fill rate of water meets an alarm value.

The present invention relates to a water level detector for fuel filters, which has, a first body and a second body, the first body and the second body being able to be joined together, jointly forming an outer enclosure of the water level detector; and components to detect water in the fuel filters housed by the outer enclosure; in that it also has, torque transfer means to transmit relative turning of the first body and the second body together, jointly forming the outer enclosure; and attachment means to establish axial retention, such that the first body and the second body remain joined together, the first body and the second body jointly forming the outer enclosure.

An operating fluid storage system for a motor vehicle having a reservoir with a filling opening and a closure cover which closes the filling opening and which can be removed from said filling opening to release the filling opening, and with at least one operating fluid outlet opening, to which an operating fluid conveyor line can be connected, for the output of operating fluid to a consumer, the system having a need sensor assembly and an output device, the need sensor assembly determines a filling need of the reservoir and outputs a corresponding need signal to the output device which acoustically, visually and/or haptically outputs a signal indicating the filling need; on the reservoir, an identification device is provided, which can be switched between at least two functional states and which is connected to the need sensor assembly via signal transmission, and which, when the need sensor assembly determines a filling need of the reservoir, is actuated by a corresponding need signal of the need sensor assembly to change the functional state thereof from a first functional state to a second functional state different therefrom.

A carbonator tank assembly is disclosed for use in a beverage machine that dispenses a carbonated beverage therefrom. The carbonator tank includes walls defining a carbonator tank interior. A probe assembly is provided for coupling in a gaseous and fluid-type manner to the walls of the carbonator tank. The probe assembly has no floats but includes electrical, elongated probes having removed ends configured to extend into the interior of the carbonator tank and near ends exposed exteriorly. An electronics module is adapt to fluidly enclose an electronics assembly therein and to receive an electrical cable carrying electrical energy from a remote source. Elements within the electronics module receive the electrical energy from the cable and provide it to the electrodes extending from the walls of the electronics module into the carbonator tank. The electrodes and the electronics module are adapted to removably couple to the probe assembly.
