A fluid tank system comprises a fluid container that includes a sensor opening in a fluid container wall defined by a rim, and a fluid level sensor comprising a radial flange on a proximate end of a longitudinally extending electronics stem that includes a distal end. The distal end of the electronic stem is inserted into the fluid container via the sensor opening and the radial flange seats on the rim. The distal end of the electronics stem is guided via a first radial support and a second radial support to a seat that is located coaxial with the sensor opening, where the first and second radial supports are longitudinally separated and radially spaced apart to allow the electronics stem to longitudinally pass between the first and second radial supports until the flange seats on the rim ensuring that the distal end of the electronic stem is longitudinally positioned adjacent to the seat.

Milk meter for measuring a milk flow provided with an inlet the milk flow is supplied to an outlet, a liquid flow path extending from the inlet to the outlet, a stabilization chamber in the liquid flow path and a float therein configured to float on milk. The level of milk in the stabilization chamber depends on the flow rate of the milk flow. At least one sensor device for determining the position of the float in the stabilization chamber for determining the flow rate of the milk flow. The milk meter has an outflow channel and an outflow opening in fluid communication with the outlet via the outflow channel. The sensor device has a first and a second coil which have a fixed distance to each other, and a third coil. The first and second coil and the third coil are displaceable relative to each other.

The invention relates to a submersible system (1) for measuring the density and/or concentration of solids in a dispersion, which can be in the form of a liquid, a mixture of multiple liquids, a suspension of solids in liquid, or a combination of these forms, inside of a reactor (11) into which gas in the form of bubbles is introduced, the system comprising: an open, pass-through gas exclusion device (4) having a tubular body (5) with a variable cross-section through which the dispersion without gas bubbles enters, the device coupling to an inlet tube (6); a scaled chamber (8) that has a means for measuring density, when the dispersion circulates between an inlet (14) of the sealed chamber (8) and an outlet (15) of the sealed chamber (8). The outlet (15) of the sealed chamber (8) is coupled to an outlet tube (7) through which the dispersion returns to the reactor (11) in which same is being processed. The system also comprises a transmitter (9) connected to a sensor, which generates an output signal proportional to the density of the dispersion without gas bubbles by means of the sensor located inside the sealed chamber (8); and a processing unit (10) that generates an output signal (16) proportional to the concentration of solids in the gasless dispersion, as well as the pulp density. The invention further comprises a method for obtaining the concentration and density of the pulp.

A system includes a material sensor system having an inlet and an outlet. The inlet receives a flow of a material and the outlet outputs the flow of the material. The material sensor system includes an inner cavity having a surface, where the inner cavity receives the flow of the material. The material sensor system also includes a float system having one or more floats, where the one or more floats float within the material of the inner cavity. The material sensor system also includes a switch that sends one or more signals to a control valve system when the float system engages the surface of the inner cavity.

A tank device for a motor vehicle includes a tank container defined by a tank wall having at least one stop region, and at least one lever sensor arranged in the interior of the tank container. The at least one stop region is an end stop for the lever sensor to prevent adhesion of the lever sensor to the tank wall.

In an array-type underwater apparatus for monitoring deformation of a reservoir landslide, an anchor is buried at an underwater monitoring point in a landslide mass, and a floating shell is configured to float on a water surface. A GPS sensor is configured to transmit and receive a GPS signal to obtain a real-time position of the floating shell, a water temperature sensor is used to obtain a water temperature-time relationship, and a gravity wave gauge is used to obtain a wave height-time relationship. An upper end of a pull cord is securely connected to the floating shell via a displacement compensation mechanism, and a lower end of the pull cord is securely connected to the anchor. The displacement compensation mechanism compensates for a displacement after the floating shell floats with a wave. An encoder-type displacement meter measures a real-time distance between the encoder-type displacement meter and the anchor.

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.

Determining a level of a liquid in a container is described. In one aspect, a container includes a calibrant liquid used for calibrating a mass spectrometer. A conductive layer is placed to float upon the calibrant liquid, and a circuit board with electrodes is arranged around the container. A controller circuit then drives and measures various electrodes to first identify which two electrodes the level of the calibrant liquid is between, and then subsequently identify a more precise location for the level between the two electrodes.
