摘要： The embodiments of the present disclosure provide methods and systems for energy measuring based on natural gas data of a smart gas meter, including establishing the gas IoT. The object platform obtains consumed gas volume data and location data of the smart gas meter as first data and second data, and sending them to the management platform through the sensor network platform. The management platform generates consumed gas preprocessing data based on the first data and the second data, and generates energy measurement data after performing the computation outside the gas IoT on the consumed gas preprocessing data by the cloud platform outside the gas IoT. The management platform sends the energy measurement data to the user platform configured in a regional pipeline network center through the service platform. The user platform performs gas energy measurement of the smart gas meter based on the energy measurement data.

摘要： A system for ascertaining fresh water consumption by an, in particular, commercial dishwasher (1) or a component thereof. The system includes a container (12, 22) for temporarily storing liquids, wherein the container (12, 22) has a liquid inlet (25), which can be flow-connected to a fresh water source if required, and a liquid outlet (23), which can be flow-connected to a freshwater consuming means, in particular a freshwater consuming means of the dishwasher (1), if required. The system further includes at least one pressure sensor (B3, B4) for detecting an, in particular, hydrostatic pressure in the container (12, 22), and an evaluation device which is designed to ascertain a fresh water volume flow into the container (12, 22) depending on at least one output value of the at least one pressure sensor (B3, B4).

摘要： A method for monitoring flow of a medium by means of a pressure difference measuring device and a Coriolis mass flowmeter having two oscillators, which comprise, in each case, a bent measuring tube pair, which are arranged on top of one another and connected for parallel flow between the two pressure measuring points of the pressure difference measuring device, comprising steps as follows: Registering a pressure difference between the first pressure measuring point and the second pressure measuring point; registering a first density measured value based on at least a first oscillation frequency of the first oscillator; registering a second density measured value based on at least a second oscillation frequency of the second oscillator; ascertaining a flow measured value based on the pressure difference, when a difference between the first density measured value and the second density measured value is less than a density difference limit value.

摘要： A sensor apparatus may include a channel structure configured to couple with an external element and a fluid conduit, such that the channel structure may receive a fluid, at least partially drawn through the external element from an ambient environment, and direct the fluid through the fluid conduit. A sensor may generate sensor data indicating a flow rate of the fluid through the fluid conduit based on monitoring a variation in a pressure at a location in hydrodynamic contact with the fluid conduit and in relation to an ambient pressure of the ambient environment. The sensor apparatus may enable generation of improved topography information associated with flows of fluid drawn from the external element based on measuring a local pressure at the location in hydrodynamic contact with the fluid conduit and determining the ambient pressure based on monitoring the local pressure over time.

摘要： Disclosed herein are various techniques and devices for detecting a level of fluid within a fluid collection receptacle. These techniques and devices may further determine a flow rate of fluid entering the fluid collection receptacle or a volume of fluid collected within the fluid collection receptacle. Sensors, including pressure sensors, may be installed in, on, or within the fluid collection receptacle to detect information about the liquid within the receptacle including fluid level, flow rate, and volume.

摘要： An ultrasonic fluid meter includes an ultrasonic measuring device, a valve comprising a movable member, a position sensor configured to measure the current position of the movable member, a pressure sensor arranged to measure the pressure of the fluid in the conduit; and a processing circuit arranged, if the current position of the movable member is such that the current flow rate cannot be measured by the ultrasonic measurement device, to evaluate the current flow rate as a function of the current position of the movable member, of the pressure of the fluid to the current flow rate, and of the pressure of the fluid at zero flow rate.
