The present invention provides a system for measuring instantaneous inflow rate of liquid, comprising: a receptacle, comprising an opening at a top side, a nozzle at a bottom and/or multiple holes on the side section of said receptacle configured to receive the inflow of liquid from said top opening, and simultaneously release said liquid through said nozzles; a sensing device, configured to sense the level of liquid within the receptacle and produce signals indicative of the level of liquid in the receptacle; and a processor, configured to receive said signals, calculate the level of liquid in the receptacle according to said signals; and analyze said calculations, to obtain the instantaneous inflow rate of liquid.

An implementation of the present teachings includes a resistor structure for measuring a level of a print material such as a liquid metal print material within a reservoir of a printer such as a magnetohydrodynamic printer. The resistor structure includes a first electrode and a second electrode that are physically and electrically separated from each other. When positioned within the reservoir, the liquid metal physically contacts the first electrode and the second electrode. An electrical resistance between the first and second electrodes changes depending on the level of the print material within the reservoir. As the level of the print material decreases, the electrical resistance between the first electrode and the second electrode increases. The electrical resistance can be measured and used to determine a level of the print material within the reservoir.

The tip has a second diameter over a first portion of the tip adjacent to the first sensing rod. The second diameter is smaller than the first diameter. The apparatus includes a sensor to detect an electrical signal between the conductor and the first sensing rod.

A tube adapter for a pipeline for conveying a medium includes a pipeline section having a tubular, first channel for inserting the pipeline section into the pipeline, and a tubular, second channel, which is arranged at a first predeterminable angle to the first channel and connected with the first channel. In a transition region between a wall of the first and a wall of the second channel, at least one hollow is present in a wall of the first and/or second channel. The present disclosure further includes an arrangement having a measuring device and a tube adapter according to the present disclosure as well as to a method for producing a tube adapter according to the present disclosure.

A humidifier tub for a respiratory apparatus is configured to deliver pressurized breathable gas to a patient's airways. The humidifier tub includes a base and a side wall defining a reservoir for containing a supply of liquid to be evaporated. In addition, the container is made of a first material. The humidifier tub also includes a heating element provided inside the container and covered by a layer. The layer includes a second material different from the first material.

Kitchen appliances usually include devices such as a water system, a cooker, a kitchen hood (range hood), an oven, a refrigerator, a microwave, a dishwasher and other devices. The devices are mostly operated independent from each other. Unlike those devices the “drinkable tap water-based liquid supply system” according to the present invention comprises a few devices controlled by an advanced control system according to the invention for providing connectivity and system management. The system is designed to provide comfort, convenience and energy saving. The water-based liquid supply system according to the present invention provides a variety of water-based liquids, dispatched with the desired properties from a countertop faucet.

A drop test measuring system and method of use is described. Embodiments of the drop test measuring system can include, but is not limited to, a control module, a liquid level measuring device, and a remotely located smart device. The liquid level measuring device can be implemented to take measurements that can allow a smart device to calculate a liquid level based on the measurements in addition to other known parameters. Typically, the drop test measuring system can be implemented in a water treatment facility implementing a filter medium.
