Abstract
A water meter (10) and a flow control valve (30) are housed in a common pressure vessel (16), in which the flow control valve (30) restricts flow through a metering chamber (18) to less than the normal flow, while still permitting a flow sufficient for basic human needs, rather than completely interrupting supply of the utility, and in which the flow control valve (30) is controlled electrically through a control valve (40) in an energy efficient manner so as to utilize power from a self-contained power source (27) in another device (25) at the customer site (50).
