Claims
- 1. A metering apparatus providing an adjustable resistance flow path for metering of fluid, said apparatus comprising:
- a. a fluid flow path for communicating fluid therealong, said fluid flow path comprising at least two alternate paths;
- b. a plurality of fluid flow restrictors operable to restrict fluid flow through the fluid flow path, each of said alternate paths passing through a different number of said fluid flow restrictors;
- at least one flow diverter that is disposable within the flow path, said flow diverter capable of diverting said fluid flow from one of said at least two alternate paths to the other.
- 2. The metering apparatus of claim 1, wherein each flow diverter will either cause the fluid flow to progress to the next fluid flow restrictor, or to bypass all remaining fluid flow restrictors.
- 3. The metering apparatus of claim 1, wherein said least one at flow diverter comprises a bypass plug, which allows said fluid flow to bypass all remaining fluid flow restrictors.
- 4. The metering apparatus of claim 1, wherein said at least one flow diverter comprises a blockage plug, which forces the fluid flow to progress to the next fluid flow restrictor.
