An automated system for venting gas from a FOB is provided replacing a conventional manual venting button at the top of a FOB with a remotely controlled vent (bleed) valve attached to the FOB. After that the venting button is reinstalled in parallel with the vent valve. The automated vent valve can be implemented as a solenoid or pneumatic valve and is controlled by a controller. A tube connects FOB's vent outlet with a waste bucket. When the FOB is vented, a mix of gas, foam, and beverage is expelled from the FOB chamber and deposited in this waste bucket.

The present invention relates to a device (1) for measuring a liquid level of a medium at a high temperature in a container (5), having a measuring unit (10) with a measurement chamber (15) and a measuring instrument (20) for determining the liquid level in said measurement chamber, and having a connecting feature (30) for connecting said measuring unit (10) with said container (5) at a distance and for transferring the medium from said container (5) into said measurement chamber (15), wherein said connecting feature (30) has an attachment adapter (35) for fastening to said container (5) and a connection adapter (45) for connecting to said measuring unit (10), wherein said attachment adapter (35) and said connection adapter (45) are arranged at a distance by at least two connecting lines (40) along an axis (X). Furthermore, the present invention relates to a refrigerating machine having such a device.

A leakage detector for a fuel vapor processing system includes a pressure sensor and a control unit. The pressure sensor is configured to measure an internal pressure of the fuel vapor processing system. The control unit is configured to calculate changes of a fuel vapor pressure from a saturation vapor pressure curve of the fuel vapor, a fuel vapor concentration of the fuel vapor in a gaseous layer within the fuel vapor processing system, and a convective velocity in the gaseous layer, to correct a reference pressure for leakage detection based on the changes of the fuel vapor pressure so as to calculate a corrected reference pressure, and to compare the internal pressure measured by the first pressure sensor to the corrected reference pressure so as to determine whether any of the fuel vapor has leaked from the fuel vapor processing system.

A reduction device includes a housing defining an input chamber configured to receive exhaust from a power source, an output chamber, an exhaust channel configured to direct the exhaust from the input chamber to the output chamber, and a longitudinal axis. The reduction device also includes a treatment unit disposed in the exhaust channel and along the longitudinal axis. The treatment unit is configured to at least partly remove pollutant species from the exhaust. The reduction device also includes an attenuation component disposed in the housing and radially outward of the treatment unit. The attenuation component is fluidly connected to the exhaust channel, and is configured to attenuate a range of frequencies corresponding to operation of the power source. Additionally, the exhaust channel prohibits exhaust entering the input chamber from exiting the housing without passing through the treatment unit.

Devices, systems and methods for leak detection are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.
