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.

A fluid meter has a first communication interface and is connected to the cut-off unit having a communication interface. If the fluid flow rate remains greater than a first predetermined flowrate threshold for at least a first predetermined duration, to detect that there is a leak of fluid and to transmit an internal command frame incorporating a closing command to the communication interface of the cut-off unit. Following closing of the electromechanical valve, to acquire a first external command frame incorporating an opening command produced by the cut-off unit following manual action on an actuator member of the cut-off unit, to produce an internal command frame incorporating the opening command, and to transmit said internal command frame via the first communication interface to the communication interface of the cut-off unit in order to reopen the electromechanical valve.

A building automation system is disclosed. Sensors positioned in the building measure a corresponding load parameter. Each load parameter is indicative as to a current electric utility demand of the building based on current energy consumption of the loads. A controller monitors each load parameter to determine whether any load parameter deviates beyond the corresponding load parameter threshold. The controller activates a graduated action when each load parameter deviates beyond the corresponding load parameter threshold to automatically adjust the current energy consumption of the corresponding load that is deviated beyond the corresponding load parameter threshold to maintain the current electric utility demand within an electric utility demand threshold. The electric utility demand threshold is a peak demand allocated to the building by an electric utility to ensure that the peak demand for energy consumption of the building is satisfied.

A system for optimizing utility consumption associated with a premises is provided. The system may include a communication device, a processing device and a storage device. Further, the communication device may be configured for receiving utility consumption information, receiving premises information, receiving lifestyle information, and performing at least one of transmitting a utility recommendation associated with the premises to an electronic device and transmitting an actuation data to an appliance associated with the premises. Further, the processing device may be configured for analyzing each of the utility consumption information, the premises information and the lifestyle information and generating at least one of a utility recommendation and the actuation data based on the analyzing. Further, the storage device may be configured for storing each of the utility consumption information, the premises information, the lifestyle information and at least one of the utility recommendation and the actuation data.

A gas meter control system is adapted for use in gas meters having a plurality of different sizes (e.g., ability to measure different flowrates and/or different gas volumes per billing cycle) and different functional capabilities. In an example, the gas meter control system is configured to recognize and identify a metrology unit, sensor(s), switch(es), valve(s), valve motor(s), and/or other device(s) within a gas meter. Having identified devices present within a gas-environment and an air-environment of the meter, the control system selects and executes appropriate software to operate the identified devices. Addition of an additional component to the meter (e.g., an earthquake sensor or a tamper sensor) results in identification of the added component and execution of appropriate control software. Accordingly, the gas meter control system replaces a number of control systems configured to operate a single specific meter and/or configuration.

A comprehensive water protection device, which is arranged on a water pipeline between a water pipeline inlet and downstream water equipment, includes a control unit, a water circuit valve installed on the water pipeline, a flow meter, a pressure gauge, and at least one of: a water quality detection probe; and a water leakage probe, which is used to monitor the water leakage point in the water pipeline and the downstream water equipment. The water circuit valve, the flow meter, the pressure gauge, the water quality detection probe, and the water leakage probe are connected to the control unit; and the flow meter, the pressure gauge, the water quality detection probe, and the water leakage probe are set in the water pipeline.

A gas meter includes a valve, or means for communicating with a valve, and a processing unit arranged for: analyzing the measurements of the gas consumption to produce predefined parameter measurements relating to the gas consumption, and detecting, from said predefined parameter measurements, one or more operating phases of at least one predetermined system of the installation; for each predetermined system, following each operating phase of said predetermined system, if a cumulated gas consumption during the current period of said predetermined system exceeds a predetermined threshold associated with said predetermined system, closing the valve until the end of said current period.

A method for linkage between an alarm based on gas and a gas meter is provided. The method is executed by the gas meter. The method includes: obtaining a detection signal through electrical connection with the alarm; determining a target alarm event corresponding to the detection signal in response to the detection signal meeting a preset alarm condition; in response to the detection signal meeting the preset alarm condition, receiving a reset instruction issued by a management platform; performing reset operation on the alarm based on the reset instruction; obtaining a reset detection signal and determining a reset alarm event corresponding to the reset detection signal; determining a credibility of the target alarm event; sending a control closing instruction to the gas meter based on the credibility larger than a preset credibility threshold, and closing a gas valve of the gas meter based on the control closing instruction.

A method for linkage alarm between a gas alarm and a gas meter is provided. The method comprises: obtaining a detection signal through electrical connection with the alarm; in response to the detection signal meeting a preset alarm condition, determining a target alarm event corresponding to the detection signal; when the target alarm event is the abnormal gas concentration in the target area, closing, by the gas meter, a gas valve of the gas meter; when the target alarm event is the abnormal operation of the alarm or the abnormal connection of the alarm, receiving a reset instruction; determining a reset alarm event corresponding to the at least one reset operation; determining a credibility of the target alarm event; determining whether to send a control closing instruction to the gas meter based on the credibility; and closing the gas valve of the gas meter based on the control closing instruction.

A method, apparatus, and system for disconnecting loads from the electrical grid are disclosed. An application programming interface (API) frontend of an advanced metering infrastructure (AMI) load shedding system may receive a load shedding activation command; in response to receiving the load shedding activation command, the API frontend may deploy a load shedding token to one or more electricity meters of the AMI load shedding system, and cause the one or more electricity meters to disconnect corresponding loads from the one or more electricity meters.
