摘要： A fluid flow meter includes a fitting attachable to a waterworks valve or pipeline so as to extend at least partially through an insertion aperture thereof. A measurement cylinder is pivotally attached to the fitting, and includes a fluid vortex generating obstruction. A sensor body extends through the fitting and has a sensor element at an end thereof disposed in the measurement cylinder and generally aligned with the obstruction to detect fluid vortices generated by the obstruction. The measurement cylinder is selectively movable from a position generally aligned with the fitting, to a position generally parallel to the fluid flowing through the valve or pipeline.

摘要： A bi-directional valve system for an aquifer thermal energy storage system includes a hydraulic control valve fluidly connected to the aquifer pump and pipeline. A control pump is selectively actuated to hydraulically open and close fluid outlets of the hydraulic control valve. When the fluid outlets are closed, a full flow of water can be pumped from the aquifer, or pressure in the pipeline of the system maintained or increased. However, when the fluid pressure needs to be reduced or water reintroduced into the aquifer, the fluid outlets of the hydraulic control valve are selectively opened.

摘要： A breakaway hydraulic coupler includes a coupler body assembly removably attachable to a fluid hydrant by a first lock member thereof. A sleeve assembly is connected to the coupler body assembly and includes a second lock member selectively movable into engagement with the first lock member to move the first lock member into locked position to attach the coupler body to the fluid hydrant. Upon an application of a load external to the hydraulic coupler exceeding a predetermined amount, the first lock member applies a sufficient force to the second lock member to cause a region of weakness of the second lock member to displace, allowing the first lock member to move to the unlocked position and the hydraulic coupler to detach from the hydrant.
