A method includes receiving a gas or gas mixture through a flow sensor. A flow velocity, volumetric, or mass flow are determined. The method also includes determining a sound velocity of the gas or gas mixture by an ultrasonic sensor. A density of the gas or gas mixture is correlated from the sound velocity. The method also includes positioning a microthermal sensor in an area with less flow or no flow of the gas or gas mixture. A thermal conductivity and thermal diffusivity of the gas or gas mixture at the one or more temperatures is determined. The method also includes connecting a processor to the microthermal sensor to calculate an energy of the gas or gas mixture based on a calorific value, the temperature and the volume or mass flow. Specific quantities for gas quality are correlated.

Closed-meshed energy measurement in the gas network

A system includes a gas meter to measure gas consumption and flow downstream for a gas regulator. The system also includes the gas regulator with an inlet connected to an upstream pipeline and an outlet connected to the gas meter. The system also includes a pressure sensor positioned within the gas meter to measure outlet pressure of the gas regulator. The gas meter is able to derive upstream pressure without an additional pressure sensor on an inlet side of the gas regulator by combining the measured gas flow and a measured regulator outlet pressure with a characterization curve of the gas regulator showing a relation between input pressure to the output pressure and to the gas flow.

Measure grid gas pressure by the residential gas meter

One embodiment is a device comprising a first and second section of a housing connected by a connection region that uses a plurality of connection elements, an inlet connected to the first or the second section, an outlet connected to the first or the second section where a gas can exit the housing, and a valve connected to the outlet, the valve capable of withstanding a first pressure in the housing.

Pressure release housing

One implementation is a device for determining the position of a valve. The device uses a current profile including at least the magnitude of current, and an analysis module for using the current profile and the state of the valve to perform at least one action.

Redundant valve position detection system

The system can include installing a gas meter in a gas supply net. The system may also include determining, by the gas meter, a level of pressure within the gas meter. The system may also include determining, by the gas meter, a flow rate level within the gas meter. The gas meter determines where a leak exists based on the flow rate level and the level of pressure. The system may also include determining, by the gas meter, a location of the leak, and whether the leak is upstream or downstream from the gas meter. The location of the leak is determined by the level of the pressure and the flow rate level. The system can also include a head end configured at a set position. The gas meter can inform the head end of the location of the leak.

Leak detection system and method

A valve without position indicating switches. Positions of the valve are detected from current magnitude measurements and current profile analytics. The current profile may be learned initially and relearned and adapted at each operation. The valve may be opened and closed by a driver that is actuated by an electrical current to control the opening and closing of the valve. The current may be regulated by a controller to open and close the valve appropriately.

Switchless valve position detection system

A security seal identification that may be matched with an identification of a utility measuring meter. This matching may be done, for instance, by a code which is imprinted on the seal and then matched to a meter number in a database, or by a code such as an encryption of the number assigned to the meter. An encryption may be read by an app on a smartphone or checked offline to determine whether the seal belongs to the meter or if it was altered or changed. A mismatch of numbers or symbols may generally indicate a change or manipulation and warrant an investigation.
