In a system for measuring a fire suppressant or fire suppression propellant quantity, the system comprising: a base (102); a top plate (106) positioned to support a tank (22) of said fire suppressant or fire suppression propellant; a plurality of springs (112) positioned between the top plate and the base to support the top plate atop the base, the plurality of springs positioned to support the top plate along a range of motion between an extended condition and a retracted condition; a first magnetic member (142) mounted to the base; a second magnetic member (140) mounted to the top plate so that a spacing between the first magnetic member and the second magnetic member decreases as the top plate moves from the extended condition to the retracted condition. At least one of the first magnetic member and the second magnetic member is a permanent magnet. A magnetic field sensor (160) is positioned to detect changes in a magnetic field associated with changes in said spacing.

The present disclosure relates to a smart bottle holder and a daily water consumption monitoring method and system thereof. The smart bottle holder includes a bottle holder main body for accommodating a bottle, and a control unit provided in a bottom part of the bottle holder main body. The control unit includes a weighing module, for obtaining a total weight of the bottle and water therein; a controller; a communication module, for sending water consumption data to an external terminal; and a power module, for supplying power to the weighing module, controller, and communication module. Compared with the prior art, the present disclosure has stronger structural mobility and wider range of applications. Also, the present disclosure is more power-saving and environmentally friendly and can provide more accurate water consumption statistics.

System and method for obtaining and recording information about cargo includes a frame defining a cargo-receivable compartment, a position determining system at least partly on the frame and that allows for determination of position of the frame, an identification system on the frame that obtains information about cargo when present in the compartment, a memory component that receives and records information about position and movement of the frame, and the obtained information about cargo when present in the compartment in association with a unique identification of the frame, and a communications system on the frame to enable communication of information to and from the memory component.

Examples of systems and methods are described herein including sensing devices and pairing sensing devices to containers. In some examples, sensing devices may be used to weigh liquid-containing containers. Responsive to changes in weight readings indicative of a change in a container being weighed by a sensing device, a user may be prompted on a user device to associate updated container size and contents with the sensing device. Systems and methods described herein may facilitate accurate inventory management and menu display of liquid available in containers.

A system for automatically measuring and recording when fluid such as urine is introduced to a fluid collection container is provided. The system includes a measuring device that includes a load cell in communication with other various electronic components. The load cell is attached on one end to a fixed object like a hospital bed. At its other end, it is attached to a fluid collection container such as a urine collection bag. When fluid is introduced into the container, the load cell detects a stress change. A strain gauge (or gauges) on the load cell detects a resistance change and reads the change as a voltage change. That voltage change is amplified and digitized and converted to a weight, volume, and flow rate, before being transmitted to a recordkeeping system like electronic medical records. The system thus provides for real time measurement of fluid output collected in the container.

A liquid product distribution network includes a keg distribution monitoring and reporting apparatus associated with a keg. The apparatus includes a radio transmitter device and sensing circuitry for sensing and communicating physical properties associating with the keg. A top or bottom chime of keg physically protects the sensing circuitry during keg distribution in the keg distribution network. The apparatus also includes a battery power supply unit fitted within and protected by the top or bottom chime. The apparatus further includes a unique identifier associated with the sensing and reporting device. The apparatus further includes a mobile communications device is configured to identify the keg based on the unique identifier associated with the sensing and reporting device embedded therein, and receive and process the radiofrequency signals from the radiofrequency signal transmission circuitry of the identified keg passively and without user interaction, for monitoring the physical properties and location of the keg.

A fluid level monitoring device and a method of use are disclosed for alerting a user that the fluid in a container, such as an intravenous (i.v.) injection or irrigation bag or collection of waste from a human body (catheter) have reached a pre-determined volume.
