Fluid metering apparatus and method
First Claim
1. A meter for metering a fluid flowing through a supply pipe and a demand pipe, comprising:
- a metering unit connectable between the supply pipe and the demand pipe and adapted to generate metering data;
a control unit, coupled to the metering unit, the control unit being adapted to determine a metered volume of fluid dispensed from the supply pine to the demand pipe in response to the metering data and to generate a metering information signal; and
an audible indicator connected to the control unit, to provide an audible metering information signal to a user in response to the metering information signal received from the control unit.

Abstract
A method and apparatus are described for controlling demand of a fluid. The method includes measuring a fluid supply pressure in a supply pipe, determining that the fluid supply pressure is lower than a predetermined threshold supply pressure, and directing a control signal from the fluid information unit to the,one or more demand control units to reduce demand for the fluid. In addition, a method and apparatus are described for measuring density of a fluid flowing through a demand pipe. The method includes determining that fluid flow through the demand pipe is stable, measuring fluid flow rate through the demand pipe, preventing the fluid from flowing into the demand pipe for a sample period of time, measuring a drop in fluid pressure in the demand pipe during the sample period, and determining the density from the measured pressure drop. Also, a utility meter for metering a fluid flowing through a supply pipe and a demand pipe having an audible indicator to provide an audible signal to a user is described.
