Abstract:
The invention is directed to a method to improve accuracy of a meter. The method first contemplates introducing a desired fluid into a valve assembly having an external casing with an inlet, outlet and interior side forming a chamber. Next, a desired fluid contacts a toggle stopper having a shaft, plate, and guides. A calibrated spring positioned around the shaft in contact with the plate assesses if the desired fluid meets a predetermined pressure. If the fluid meets this threshold, the calibrated spring compresses thereby toggling plate within the chamber to allow desired fluid to enter the chamber. Should the total pressure of the desired fluid and/or an undesired fluid create a pressure that fails to meet the predetermined pressure, the calibrated spring expands to seal the valve assembly. Upon such seal, there is an equalizing of both the desired and undesired fluids to the same pressure by decreasing the volume of the undesired fluid, causing the calibrated spring to compress and reopen.

Claim (Index 11):
A method of improving the accuracy of a meter employed to measure a desired fluid, comprising the steps of:\n (a) introducing the desired fluid into a valve assembly having an external casing which includes an inlet, a corresponding outlet, an exterior side and a corresponding interior side forming one or more chambers; (b) contacting the desired fluid with a second side of a plate positioned within the exterior casing, the plate being part of a toggle stopper also having a shaft and one or more guides; (c) determining whether the desired fluid is at or greater than a predetermined pressure through use of a calibrated spring positioned around the shaft of the toggle stopper, the calibrated spring in contact with and capable of exerting force on a first side of the plate, (d) if the desired fluid meets or exceeds the predetermined pressure, compressing the calibrated spring resulting in toggling the plate within the chamber and allowing the desired liquid to flow through chamber to exit the outlet; (e) should the total pressure of the desired fluid and an undesired fluid create a pressure which fails to meet the predetermined pressure, expanding the calibrated spring so as to position the plate in proximity of the inlet to seal the valve assembly and prevent both the desired fluid and undesired fluid from entering; and (f) equalizing both the undesired fluid and desired fluid to essentially the same pressure by decreasing the volume of the undesired fluid in order to reach the predetermined pressure to allow the calibrated spring to compress and re-open the valve assembly to resume flow.
