1. A fluid flow measurement device comprising:

  • a fluid conduit structure comprising a first port and a second port in fluid communication through a chamber;

    two or more rotating members in the chamber, each of the members having substantially parallel axes of rotation, wherein rotation of the rotating members positively displaces a fluid in the chamber between the first and second ports, wherein the rotating members are rotatable when driven by a fluid flowing between the first and second ports;

    a meter to detect rotation of at least one of the rotating members and to determine therefrom a measurement of a volume of fluid communicated between the first and second ports; and

    an actuator to automatically control rotation of the rotating members to manipulate a fluid flow through the meter in response to a control signal.
