  • Method and system for controlling fluid transportation in a pipe network
    Patent number: 4569012
    Abstract: Method and system for controlling fluid transportation in a pipe network are disclosed. Pressures and flow rates at a predetermined number of points in the pipe network which number is smaller than the number of demand nodes in the pipe network are detected, demand volumes at the demand nodes are estimated based on known flow and pressure balance requirements for the pipe network and the detected flow rates and pressures, and the flow transportation in the pipe network is controlled in accordance with the estimated demand volumes such that the pressures at the demand nodes are brought to a reference pressure so that the pressures at the demand nodes at points other than the predetermined points are also brought to the reference pressure.
