An example pressure-sensing device includes a pipe or conduit having upstream and downstream connectors for respective upstream and downstream transducers to measure fluid (e.g., water) flow. The conduit may be made at least in part of a resiliently deformable material. A deformable electrode of a capacitor may be mounted in contact with a dry-side surface of an area of the resiliently deformable material. The wet-side surface of the area may define part of a pathway for a flow of the fluid. In operation, the area of the resiliently deformable material changes a location and/or a shape of the deformable electrode in response to changes in fluid pressure. A fixed electrode of the capacitor is separated by a dielectric material (e.g., air or an insulator) from the deformable electrode, and a circuit determines a pressure of the fluid based at least in part on a capacitance between the deformable electrode and the fixed electrode.

METROLOGY MODULE ADAPTABLE FOR USE IN MULTIPLE GAS METERS
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.

Techniques to provide a unified system for fluid pressure and fluid flowrate measurement are described. Upstream and downstream transducers include piezo devices, and are in contact with a fluid flow, such as in a pipe within a metering device. In an example, a first signal is sent from the upstream transducer to a downstream transducer, and time-of-flight of the first signal is measured. A second signal is sent from the downstream transducer to the upstream transducer, and a time-of- flight of the second signal is measured. A flowrate of the fluid flowing within the passage is calculated, based on the times of flight of the first and second signals. An electrical signal is sent to the first transducer. Upon conclusion of the electrical signal, a pressure of the fluid flowing within the passage is calculated, based at least in part on time of decay of a second electrical signal generated by vibration of the first transducer.

A gas meter having a sensor module and at least one bypass module is described herein. In an example of the gas meter, an enclosure defines an interior cavity within which a manifold may be configured to include a sensor module connector, at least one bypass module connector, and an exhaust port. A sensor module may be connected to the sensor module connector of the manifold and may measure a flowrate through the sensor module and into the manifold.

Techniques are directed to opportunistically communicating using a modulation scheme that is other than the preferred modulation scheme, to update communication metric data for the second modulation scheme, such as a modulation scheme that has not been used as much as the first modulation scheme. The second modulation scheme may be associated with a higher data rate than the preferred modulation scheme. If communication using the second modulation scheme is successful, subsequent communication may be carried out exclusively using the second modulation scheme, and the communication metrics may develop such that the second modulation scheme becomes the preferred modulation scheme.
Techniques are directed to using communication metric data associated with multiple modulation schemes to achieve a link quality metric that is representative of the link as a whole, across the multiple modulation schemes that may be employed on the link. A calculation of a link quality metric may be triggered by a network layer transmission attempt, with communication metrics accumulated at the link layer of the link. A filter used to calculate the link quality metric may be updated based on network layer transmission attempts, based on successful and/or unsuccessful transmissions at a Media Access Control (MAC) layer of the link. More generally, a calculation of link quality may be triggered by a higher layer transmission attempt while being calculated based on transmission attempts at a lower layer of the link.

First and second flow pipes receive incoming gas and bifurcate the gas flow, which is redirected at the first curved ramp. The fingers contact and remove particles in the redirected gas flow. A second curved ramp may include at least one hole to bifurcate the gas flow into a first gas flow passing through the at least one hole and a second gas flow redirected by the second curved ramp to pass through the plurality of openings defined in the upper portion.

Techniques for controlling packet transmission levels in a multi-hop network may be performed in a distributed manner. Load-control functionality may be distributed among a plurality of nodes within a network, allowing such nodes to send feedback to upstream nodes, and receive feedback from downstream nodes. In an example, received packets are measured, such as by summing sizes of received packets over time, to determine a received traffic-level. Transmitted packets are measured, such as by summing sizes of transmitted packets over time, to determine a transmitted traffic-level. Feedback may be sent to at least one source of the received packets based at least in part on the received traffic-level and the transmitted traffic-level. The feedback may indicate a desired rate for the sender to transmit. A node may receive data from upstream node(s) and from an internal device, such as a metrology unit. Both data sources may be controlled by feedback.
Methods and devices for providing routing path and transit delay time data to a device running traceroute on an IP network comprising routing tunnels are described herein. In examples, a tunnel entrance device may copy a hop limit value associated with a traceroute probe into a hop limit field of a tunneled IP header. In other examples, the tunnel entrance device may perform address spoofing to generate an error message with a source address corresponding to an intermediate device disposed within a routing tunnel. In this way, a device executing traceroute may be able to receive network addresses corresponding to intermediate devices in a routing tunnel in order to perform network diagnostics, construct routing tables, determine more efficient routing paths, and so on.

Techniques for providing additional timing information in periodic beacons in a network to enable battery powered devices to determine more appropriate listening windows for receiving the periodic beacons are described herein. In some examples, the battery powered devices use the additional information to determine more accurate listening windows based on a drift time of their internal clocks, and a jitter time of the network and/or a Coordinated Universal Time (UTC). Additionally, techniques for modifying when mains powered devices update their internal clocks based on transmission of beacons to downstream devices are described herein. For instance, the mains powered devices may refrain from updating their internal clocks to an updated network reference time until transmission of downstream beacons have occurred. In this way, timing synchronization of devices in a network may be improved, and battery life of battery powered devices in the network may be extended.
Techniques directed to servicing communications based on when communication sessions are initialized for nodes are described. For example, a routing device may prioritize packets in a buffer according to when nodes have initiated communication sessions with a service provider or another node. The routing device may give priority to nodes that have first initiated communication sessions. This may avoid communication sessions ending prematurely due to time-out periods and/or avoid delays in completing communication sessions.
Techniques directed to attributing information regarding communications with a modulation scheme to a different modulation scheme are described. In one example, a successful communication for a higher data rate modulation scheme may be attributed to a lower data rate modulation scheme. Such attribution may infer that the lower data rate modulation scheme would have also been successful if it had been used. In another example, an unsuccessful communication for a lower data rate modulation may be attributed to a higher data rate modulation scheme. Here, such attribution may infer that the higher data rate modulation scheme would have also been unsuccessful if it had been used.
Techniques for employing a Mains Powered Device as a proxy for communicating on behalf of a Battery Powered Device are described herein. In some examples, the Mains Powered Device may be a parent node to the Battery Powered Device in a network which operates using a Routing Protocol for Low -Power and Lossy Networks (RPL). The Mains Powered Device may detect and/or forward a Destination Advertisement Object (DAO) transmitted from the Battery Powered Device to a DODAG root of the network, and begin to perform subsequent transmission of DAOs on behalf of the Battery Powered Device. In this way, the Mains Powered Device updates a routing table of the DODAG root periodically to include an indication of the Battery Powered Device as existing in the network, while extending the battery life of the Battery Powered Device by transmitting DAOs on behalf of the Battery Powered Device.

Determination of electrical network topology and connectivity are described herein. A zero-crossing is indicated at a time when the line voltage of a conducting wire in an electrical grid is zero. Such zero-crossings may be used to measure time within a smart grid, and to determine the connectivity of, and the electrical phase used by, particular network elements.

A phase difference may be determined between the first meter and the reference meter from which the PAD message originated. The first meter may pass the PAD message to additional meters, which propagate the message through the network. Accordingly, an electrical phase used by meters within the network may be determined.
