The present invention relates to a non-contact continuous type sensing device for a flowmeter and a sensing method thereof. The flowmeter includes a movable member that is connected to an operating member and that is driven by a fluid to move, thereby moving the operating member. A projector is mounted above the operating member and projects signals onto the operating member. At least two regions are defined in a side of the operating member facing the projector. At least one of the at least two regions includes metal material to reflect the signals projected thereon. A signal density in a space between the projector and the operating member is changed when the operating member is passing through the space, such that the projection power of the projector is affected to thereby sense a movement condition of the operating member and to thereby continuously know a flowing condition of the fluid.

Systems and methods for providing a cloud flowmeter are provided by certain embodiments of the disclosure. According to one embodiment of the disclosure, there is disclosed a method, which can include receiving, from a meter device, at least one flow signal via at least one network; determining, based in part on the at least one flow signal, at least one flow characteristic, data characteristic, or meter characteristic; and storing the at least one flow characteristic, data characteristic, or meter characteristic in a data storage device remote from the meter device.

An apparatus for use with a backup counter module, the apparatus having: a housing having a first end for coupling the housing to a gas meter body, and a second end for coupling an electronic counter module to the housing; and the second end having an inner surface with at least two sets of backup counter module engagement features for securing an output end of a backup counter module in one of at least two backup counter module positions. The housing may be coupled to a first gas meter body with a backup counter module positioned within the housing in one of the at least two backup counter module positions. The housing may alternatively be coupled to a second gas meter body with the backup counter module positioned within the housing in another of the at least two backup counter module positions.

A signal relay may include sensor leads configured to be communicatively coupled to sensor leads of said flow sensor, wherein the sensor leads are configured to connect to a plurality of different flow sensors. A signal relay may include memory in communication with the sensor leads, the memory configured to store measurements from said flow sensor. A signal relay may include a wireless transmitter configured to transmit the measurements to a remote computing device.

A vortex flow includes a flowtube configured to receive a flow of process fluid. A shedder bar is disposed within the flowtube and is configured to generate vortices in the flow of process fluid. A vortex sensor is disposed to sense vortices in the flow of process fluid generated by the shedder bar. Measurement electronics are operably coupled to the vortex sensor and are configured to detect an analog signal of the vortex sensor and provide a digital indication relative to the analog signal of the vortex sensor. A processor is configured to receive the digital indication and calculate velocity of the process fluid flow based on a frequency of the digital indication. The processor is also configured to measure an amplitude of the digital indication and estimate density of the process fluid based on the measured amplitude. The processor is further configured to determine a fluid type based on the measured amplitude and assign a unit of flow corresponding to the calculated velocity to a fluid totalizer corresponding to the detected fluid type.

A pressure gauge of a fluid pressure system includes a measurement unit, a case, a display unit, and an adapter. The adapter includes an attachment hole. The case includes an attachment convex portion which can be fitted into the attachment hole. The display unit includes a display surface oriented in a direction intersecting an axis of the attachment convex portion. The attachment convex portion and the attachment hole have a fitting structure capable of changing the relative position between the attachment convex portion and the adapter in the circumferential direction about the axis of the attachment convex portion.

Meter for a fluid includes: a casing crossed by the fluid to be measured; inlet and outlet mouths for the flow of the fluid; a detection module housed in the casing that detects one or more quantities relating fluid passing through the casing; a processing section that includes: a first containment structure external with respect to the casing; a first electronic control and/or processing unit housed inside the first containment structure; first optical communication means mounted on and/or housed in the first containment structure; and a communication section which includes: a second containment structure external with respect to the casing, a communication module, second optical communication means, and a second electronic control and/or processing unit.

The first and second containment structures are removably mechanically associable with each other so that, when associated with each other, the first optical communication means are capable of communicating with the second optical communication means.
