This invention discloses a method and system for monitoring the liquid glass level in a furnace during substrate glass preparation, belonging to the field of substrate glass manufacturing technology. It solves the technical problem that existing technologies cannot achieve real-time monitoring and adjustment of the liquid glass level in a substrate glass furnace to ensure its stability. The method involves collecting weighing data of glass powder and substrate glass, and calculating the theoretical height of the liquid glass level in the furnace. Subsequently, a glass volume conversion coefficient is set, and the actual liquid glass level is manually measured. The theoretical and actual liquid glass levels are compared to correct the volume conversion coefficients for melting glass powder and substrate glass. By comparing the difference between the theoretical and target liquid glass levels, the feeding frequency of the feeding system is adjusted, thereby achieving adjustment and stability of the liquid glass level in the substrate glass furnace.

A humidifier of the present invention comprises: a main body; a lamp provided in the main body; a display unit provided in the main body; a water tank accommodated in the main body; a weight sensor for sensing the weight of water stored in the water tank; a temperature sensor for sensing the temperature of the water stored in the water tank; and a control unit for controlling an output of at least one of the lamp and the display unit on the basis of at least one of the sensed weight of the water and the sensed temperature of the water.

The present invention relates to a humidifier and a method for controlling same. The humidifier of the present invention comprises: an input unit for receiving a user input; water tanks which include a first water tank, and a second water tank provided inside the first water tank, and which store water by means of the first and second water tanks; a heating source for heating the water stored in the water tank; and a temperature sensor for sensing the temperature of the water stored in the water tanks, wherein initial temperature information sensed by the temperature sensor is recognized on the basis that a humidification mode execution command is received through the input unit, the output reduction information of the heating source for each humidification operation time is recognized on the basis of the recognized initial temperature information, and the output of the heating source is controlled on the basis of the recognized output reduction information of the heating source for each humidification operation time.

Apparatus and method for automatically measuring precipitation using a precipitation-collection bowl configured to selectively spin around a vertical axis under control of a controller in order to empty, from time-to-time, any collected precipitation, as well as expelling debris that may land on the bowl. In some embodiments, a load cell is configured to weigh the bowl and collected water to determine the amount of collected precipitation and report the amount of collected precipitation to external equipment. Some embodiments use an electrical motor, such as a gearmotor or stepper motor, to spin the bowl. Some embodiments periodically measure the weight of the motor and bowl, and detect debris by sensing a sudden short-term change in a rate of measured precipitation.

The systems and methods taught herein provide an eluent level sensor that enables real-time monitoring of the level of eluent or waste liquid in a container placed on the eluent level sensor. The eluent level sensor alerts the user if the liquid level of the eluent falls below or exceeds a selectable threshold appropriate for the specific contents of the container. For example, the eluent level sensor can alert the user if the liquid level of the eluent falls below a selectable threshold in a container holding new eluent or eluent precursor. In an eluent delivery system, this helps the user save significant analysis time and effort by alerting them before the container is empty. The eluent level sensor can improve the user experience and avoid damage to instrumentation by notifying the user of the eluent level (e.g., visually).

A rail vehicle includes a truck having wheels for engaging a railroad track, a bolster supported by the truck, and a tank supported by the bolster for storing a lading. A measurement system measures the level of the lading within the tank and includes gauges and a controller. The gauges are disposed at selected points on the bolster for sensing at least one of lateral and longitudinal localized displacement experienced by the bolster during motion of the rail vehicle. The controller calculates the level of the lading within the tank and compensates for changes in the level of the lading during motion of the rail vehicle in response to signals generated by the gauges.

A system for managing liquid intake The invention provides: a system for managing liquid intake comprising: a drinking vessel; a first sensor for sensing, in use, a specific characteristic of liquid in the drinking vessel; a display unit, attachable to an outer side surface of the drinking vessel, having a display screen disposed so as to face outwardly when the display unit is attached to the drinking vessel; an electronic database of substances to be consumed as or with a dose of liquid, with information about the recommended specific characteristic of the liquid dose to be consumed for each substance; an information input, configured to receive information identifying a substance to be consumed from the drinking vessel; and a processor, configured to: receive, from the information input, the identity of a substance to be consumed from the drinking vessel; retrieve, if available, information from the electronic database about the recommended specific characteristic of the liquid dose to be consumed for the identified substance; monitor, in real time, the specific characteristic of liquid in the vessel as determined by the first sensor; and control the display unit to generate a user notification that the specific characteristic of the liquid in the drinking vessel is as recommended, when this is the case.
