The present invention provides for a device or feature that incorporates a technique or means for flow measurement in a fluid flow system. By way of example, a contoured insert may be specifically calibrated to the pipe line size to ensure the desired accuracy of the flow measurement, irrespective of pipe length between the device and other fluid system components that would negatively influence other flow rate measurement devices. This in turn reduces the total number of components needed in a system.

Contoured insert for flow verification

A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion, and has two sides, a first side to respond to the fluid flow in a first direction and move the check valve portion away from a fluid opening to the one or more open positions depending on the fluid flow to allow the fluid to flow through the fluid opening, and a second and opposing side to respond to fluid flow in an opposite direction through the fluid opening and move the check valve portion towards the fluid opening to the closed position to seal the fluid opening and stop fluid flow. The check valve portion a near-sloped portion formed nearest to the pivot portion, having a near-sloped contoured surface curving away from the pivot point to a first point of inflection with a first curvature, and a far-sloped portion formed farthest from the pivot portion, having a far-sloped contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature, the near-sloped portion and the far-sloped portion combining to form a combined surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.

Contoured check valve disc for low cracking pressure

A suction diffuser or arrangement is provided featuring a main suction diffuser body and a flow conditioning arrangement. The main suction diffuser body is configured with an inlet to receive an incoming fluid flow, an interior cavity to receive the incoming fluid from the inlet, and an outlet to receive the incoming fluid from the interior cavity and provide an outgoing fluid. The flow conditioning arrangement is configured in relation to the inlet and also comprises a flow conditioning portion having at least one inwardly contoured surface, configured to extend into the interior cavity, diffuse the incoming fluid passing from the inlet into the interior cavity, and provide a flow conditioning that produces a uniform flow of the outgoing fluid by directing the incoming fluid towards the outlet, based at least partly on a contoured design corresponding to the at least one inwardly contoured surface.
