Water Meter With Magnetically Driven Flow Restriction Valve
First Claim
1. A utility flow meter including a magnetically driven valve, the meter having a pressure vessel providing a flow path from a meter inlet to a meter outlet, the valve comprising:
- a valve member positioned within the valve in the pressure vessel for movement between an open position, allowing normal flow through the flow meter and a flow restriction position in which flow through the flow meter is limited to less than the normal flow; and
an electrically operable control device for controlling movement of the valve member including a dry-side magnet assembly and a wet-side magnet assembly,wherein the electrically operable control device receives command signals to rotate the dry-side magnet assembly to move the valve member and thereby increase or decrease flow through the metering chamber.

Abstract
A utility flow meter including a valve having a pressure vessel providing a flow path from a meter inlet to a meter outlet through the valve is magnetically driven. The meter includes a valve member positioned within the valve in the pressure vessel for movement between an open position allowing normal flow through the flow meter and a flow restriction position in which flow through the flow meter is limited to less than the normal flow and an electrically operable control device for controlling movement of the valve member including a dry-side magnet assembly and a wet-side magnet assembly. The electrically operable control device receives command signals to rotate the dry-side magnet assembly to move the valve member and thereby increase or decrease flow through the metering chamber.

16. A magnetically driven valve for controlling movement of a valve member in a flow path, the valve comprising:
-
a valve member positioned within the flow path for movement between an open position allowing normal flaw and a flow restriction position in which flow is limited to less than the normal flow; and
,an electrically operable control device for controlling movement of the valve member including a dry-side magnet assembly and a wet-side magnet assembly, wherein the electrically operable control device receives command signals to rotate the dry-side magnet assembly to move the valve member and thereby increase or decrease flow along the flow path. - View Dependent Claims (17, 18, 19, 20)

21. A utility flow meter including a valve having a pressure vessel providing;
- a flow path from a meter inlet to a meter outlet through the valve, the valve comprising;
a pressure vessel formed to contain the valve positioned downstream from a flow measurement system in a pressure vessel having a same length as a standard water meter; a valve member positioned within the valve in the pressure vessel for movement between an open position allowing normal flow through the flow meter and a flow restriction position in which flow through the flow meter is limited to less than the normal flow; and an electrically operable control device for controlling movement of the valve member including a dry-side magnet assembly and wet-side magnet assembly, wherein the electrically operable control device receives command signals to rotate the dry-side magnet assembly to move the valve member and thereby increase or decrease flow through the metering chamber.
- a flow path from a meter inlet to a meter outlet through the valve, the valve comprising;
