Abstract

An apparatus and method for metering fluid flow is disclosed. A fluid dispensing unit (30) is coupled between a supply pipe (28) and a demand pipe (32), and dispenses fluid received from the supply pipe (28) to the demand pipe (32). The demand pipe (32) is coupled to one or more fluid-expending appliances. The pressure of the fluid in the demand pipe (32) is monitored by a fluid information unit (34). The fluid information unit (34) and fluid dispensing unit (30) cooperate to maintain the fluid flowing through the demand pipe (32) at a substantially constant demand fluid pressure by monitoring fluid flowing through the demand pipe (32) and actively dispensing fluid received from the supply pipe (28) into the demand pipe (32) to maintain the demand fluid pressure at a pre-established demand pressure level. The fluid information unit (34) and fluid dispensing unit (30) also cooperate to meter or measure the volume of fluid dispensed through the fluid dispensing unit (30).
