A milk meter for measuring a flow rate of a milk flow with an inlet and an outlet a liquid flow path from the inlet to the outlet, a stabilization chamber in the liquid flow path and a float in the stabilization chamber configured to float on milk the milk meter is configured so a level of milk in the stabilization chamber depends on the flow rate of the milk flow, and is provided with a magnetic unit in the stabilization chamber, the magnetic field varies in a height direction of the stabilization chamber, an electronic measuring unit is arranged in the float for measuring the strength of the magnetic field, the strength is a measure of the height within the stabilization chamber at which the float is floating on the milk and the strength of the magnetic field is a measure of the flow rate of the milk flow.

A reservoir assembly comprising a lower manifold, an upper manifold, a reservoir body, a float member and a sensor system. The upper manifold has an upper cover placed over a central bore, and sealingly engaged therewith, the upper cover being at least partially transparent. The reservoir body has a lower end sealingly engaged with the lower manifold and the upper end sealingly engaged with the upper manifold. The float member is positioned within the reservoir and can slidably move between the upper and lower manifolds. The float member has an upper target that is substantially parallel to an upper cover positioned on the upper manifold. The sensor system has a float position sensor positioned over the upper cover and targeting the upper target of the float member to, in turn, determine the position of the float member relative to the float position sensor.

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.

A system, method and apparatus for providing real-time alerts regarding the status of agricultural infrastructure resources, which may be stationary and/or mobile, such as water level, water temperature, trough, water pump, drone, and livestock that are equipped with sensors. The system adaptively aggregates and processes the sensed data from multiple resources and animals using low cost readily available wireless local network and sends an alert cost effectively using various messaging methods, such as SMS, MMS, PSTN, VoIP, HTTP, and HTTPS, over various wireless communications networks, such as cellular, satellite, or UHF, depending on availability, cost and quality of service.

The present disclosure provides methods for the automated control of aspects of slide preparation in an automated slide preparation instrument. Aspects of the methods include automated assessments of reagent amounts, quality and performance as well as automated adjustments of reagents based on such assessments, including the adjustment of reagent amounts, e.g., as present in reagent baths, the adjustment of reagent compositions and the replacement of reagents. Devices and systems useful in performing the described methods are also provided herein.

A sensor arrangement for measuring liquid height in a tank can include a housing, a transducer, and a couplant. The housing can have an interior and an aperture, the aperture placing the interior of the housing in communication with the environment external to the housing. The transducer can be seated within the aperture. The couplant can be mechanically connected to the transducer and can have a compressible couplant body. The couplant body can extend between the transducer and the external environment for transmitting an acoustic pulse from the transducer to a tank bottom for measuring height of a liquid overlaying the transducer.

The invention relates to a device (1) for determining a filling level of a liquid (F) in a container (B), comprising a submersible unit (2) having a pressure sensor unit (3) and a transmitter unit (14) configured as a radio transmitter unit, an ultrasonic transmitter unit or a light signal transmitter unit, and a float unit (5) having a further pressure sensor unit (6) and a further transmitter unit (15) configured as a radio transmitter unit, wherein the further pressure sensor unit (6) is arranged at or in a floating body (7) of the float unit (5) in such a manner that, if the float unit (5) is arranged in the liquid (F) for which the device (1) is intended to determine the filling level, the further pressure sensor unit (6) is arranged below the surface (O) of the liquid (F).

Humidifiers can include a liquid tank removably attachable to a base portion. The liquid tank can include an upper connector configured to engage a lower connector of the base portion when the liquid tank and the base portion are attached. The liquid tank can include a touch interface configured to receive a touch input from outside of the liquid tank and a liquid level sensor configured to output a signal representative of a level of liquid in the liquid tank. The base portion can include a controller that is in electrical communication with the liquid level sensor and the touch interface when the upper connector engages the lower connector. The controller can be configured to adjust operation of the humidifier based on signals received from the touch interface and can receive signals from the liquid level sensor representative of the amount of liquid in the liquid tank.
