Abstract: The present invention relates to methods for operating and controlling flow control systems. The method includes sensing an actual medium flow through a pipe part and outputting an electrical signal indicative of the sensed actual medium flow; comparing the sensed medium flow with a set medium flow and outputting a control signal; using an orifice adjusting system to adjust an adjustable orifice in a pipe part in response to the control signal; and performing a correction of a characteristic curve. The method can include setting an upper limit for medium flow to Vmax wherein Vmax is less than a maximum medium flow.

Abstract: The present invention relates to a flow control system for controlling a flow of a medium passing through a pipe part of a pipe system via which the medium is distributed from a common source to a plurality of consumer devices. The flow control system comprises a flow sensor for sensing an actual medium flow through the pipe part, a controller in communicative connection with the flow sensor and provided for evaluating the electrical signal indicative of the sensed actual medium flow with a value representing a set medium flow and an orifice adjusting system in communicative connection with the controller and provided for adjusting the adjustable orifice in response to the control signal received from the controller. The flow sensor is arranged outside the flow chamber and has a static measurement principle based on a wave propagating in the medium.
