A sensor assembly that includes a sealed housing. A printed circuit board assembly including a first section that includes processing circuitry is disposed within the sealed housing and a second section that includes detection circuitry extends from the sealed housing. The sensor assembly also includes a conductive target movably coupled to the second section of the printed circuit board to vary net voltage of the detection circuitry as the conductive target moves along the second section to provide an output signal. The processing circuitry detects the output signal and converts the output signal into a linear representation of position of the conductive target in relation to the second section.

A pool pumping apparatus for maintaining a constant level of water in a swimming pool includes a conduit having a lower end defining an inlet and an outlet that are open, the conduit defining an interior area through which water is channeled between the inlet and outlet. The apparatus includes a pump in fluid communication with the inlet of the conduit, the pump having a motor configured to transfer water from the inlet to the outlet when energized. In addition, a float assembly includes a housing that defines an interior space and includes a float member positioned in the interior space, the float assembly including a cord extending from the float member operable for setting the float member at a selected level. The float member is electrically connected to the pump and configured to energize the pump when the float member is above the selected level.

A remote monitoring system that controls fluid level in fuel storage tanks of mining trucks includes a device that measures fluid level in fuel storage tanks of mining trucks resistant to rapid filling that protects a sensor inside the device, including a protective metallic tube; a level sensor arranged inside the protective metallic tube; and an anchorage system connected to the protective metallic tube with the tank allowing fluid communication inside the tank with fluid inside the protective metallic tube; antennas; Web server; remote means; and a power source.

In one embodiment, an apparatus may meter a level of a liquid. The apparatus includes a float component, wherein the float component includes a sensor and a controller. The sensor senses a parameter usable to determine an inclination of the float component. The controller is operable to receive the sensed parameter, and communicate information based on the sensed parameter to an external controller. When operating to determine a level of a liquid within a container, the apparatus physically contacts the container. Further, at least one of the controller or the external controller is operative to estimate the inclination of the float component based on the sensed parameter, and determine the level of the liquid within the container based on the estimated inclination.

A method for monitoring an amount of a chemical material that includes: providing an at least one portable container; and providing into the at least one portable container a first amount of the chemical material. The method includes operatively associating a sensor with the at least one portable container, the sensor effective to detect a first level of the chemical material in the at least portable container and to generate a first data signal based on the first level. The method includes operating the sensor to detect a change in the amount of the chemical material in the at least one portable container, and thereby to generate a second data signal based on the change. The method includes using a processor in operable communication with the sensor.

A milk meter for measuring a flow rate of milk, having an inlet, an outlet, and a liquid flow path from the inlet to the outlet, the milk meter has a stabilization chamber in the liquid flow path and a float in the stabilization chamber configured to float on the milk, wherein the milk meter is configured so the level of milk in the stabilization chamber depends on the flow rate of the milk flow, the milk meter also has a magnetic unit for generating a magnetic field in the stabilization chamber, which varies in a height direction of the stabilization chamber, the float contains an electronic measuring unit for measuring the strength of the magnetic field, which is a measure of the height within the stabilization chamber of the float and the strength of the magnetic field measures the flow rate of the milk.

The invention relates to an articulated vehicle, for example a rail vehicle or an articulated bus, formed from a plurality of vehicles or vehicle parts (2, 3) connected to one another in an articulated manner, wherein a passage (10) is arranged between the vehicles or vehicle parts (2, 3), wherein the passage has an inner cladding (12) and an outer cladding (14) laterally spaced apart from the inner cladding, wherein the inner (12) and outer cladding (14) are arranged so as to form the spacing (A) relative to one another on the end walls of two adjacent vehicles or vehicle parts, wherein a sound insulation layer (18) can be applied to the free surface (16) formed by the spacing (A) on the end wall.

A float floats on a liquid inside a container and is movable upward and downward according to a liquid surface level. A cover is located inside the container and houses the float inside the cover. A detector detects the position of the float. The cover includes a support part and a wall part. The support part allows upward and downward displacement of the float and restricts displacement of the float outward from the cover. The wall part is located around the support part. The wall part has an opening that allows communication between the inside of the cover and the outside of the cover. The area of the opening is larger than the surface area of the wall part except the opening.

An improved evaporation pan assembly and measurement method comprising adjustable buoyancy floats attached to an outer wave-guard that surrounds the evaporation pan. An anchor system preferably restricts lateral movement while allowing for vertical movement with changing fluid levels. Preferably, the evaporation pan assembly further comprises a baffle system within the evaporation pan to prevent sloshing of the fluid within the pan. The height of the body of fluid being evaluated is preferably measured with a guided float assembly within the evaporation pan.
