Claims (20)
1. A system for a controlling the flow of fluid in a tube network, the network comprising a fluid forward tube and a fluid return tube, between which there are provided a number of parallel tube strings to constitute parallel fluid circuits, - each string having a flow regulation valve for regulating the flow through the string, - each valve having a flow gauge for measuring the flow through the valve, - the system comprising a number of transmitters, wherein each of the flow gauges is connected to a transmitter and configured for transmission of measurement data from the transmitter, wherein the transmitter is configured for wireless transmission of the measured flow data together with a unique ID to a central computer for relating the received flow measurement to the corresponding valve, - the central computer being configured for receiving the measured flow data from the transmitters through wireless transmission, - wherein the central computer has a display for displaying data for control of the flow measurements and with a keypad for receiving user commands for the flow adjustment.
2. A system according to claim 1, wherein the computer is a handheld device.
3. A system according to claim 1 or 2, wherein the unique ID is comprised by an electronic circuit of the corresponding valve and wherein the electronic circuit is functionally connected to the transmitter for transmission of the ID.
4. A system according to any preceding claim, wherein the computer is configured for pre-selection of the IDs of a number of valves and for programming through the keypad to only receive or display measurements from the pre-selected transmitters.
5. A system according to claim 4, wherein the central computer is configured to indicate on the display the flow of the pre-selected valves.
6. A system according to any preceding claim, wherein the central computer is configured to indicate an alert on the display, the alert comprising the ID of a valve for which the flow through the valve is below a predetermined threshold value.
7. A system according to any preceding claim, wherein the transmitter is a transceiver configured for receiving a trigger signal from the central computer for initiating transmission of flow data to the computer.
8. A system according to claim 7, wherein the transceivers are configured to transmit a sequence of polling signals with a predetermined time delay between consecutive polling signals as requests for receiving a trigger signal from the central computer, wherein the transceivers are programmed to await a trigger signal before transmission of flow data.
9. A system according to claim 8, wherein the computer is configured for selection of a number of valve IDs and configured for only sending a trigger signal to these selected valves.
10. A system according to claim 8 or 9, wherein the flow gauges are configured for performing and transmitting measurements until a second trigger signal is received.
11. A system according to claim 8 or 9, wherein the flow gauges are configured for performing and transmitting further measurements only if the flow through a valve changes more than a predetermined value.
12. A system according to any preceding claim, wherein the central computer is configured for transmission of desired valve setting signals to each valve, wherein each valve comprises an automated electric actuator for regulation of the valve, the actuator being connected to a receiver configured for receiving a wireless data signal from the central computer indicating the desired valve setting and configured for automatically adjusting the valve in response to the signal.
13. A system according to claim 12, wherein the computer is configured to transmit a valve setting for continuous flow reduction of the valve until a valve setting stop signal is received.
14. A system according to any preceding claim, wherein the fluid network is a central heating system.
15. A system according to any preceding claim, wherein each flow regulation valves has a venturi inside the valve for flow measurements.
16. A system according to any preceding claim, wherein the regulation of a valve in a string influences the flow through other valves in other strings, wherein the computer is configured for calculating an optimal flow in the tube network in accordance with predetermined flow parameters, and configured for calculating a setting of the flow through each valve to achieve the optimal flow.
17. A system according to claim 15, wherein the central computer is configured for calculating the regulation of the valves in accordance with a predetermined proportional balancing model for a sequential regulation of the valves in dependence on a valve position in the network.
18. A system according to claim 15 or 16, wherein the computer is configured to await receipt of flow measurement data from selected transmitters before calculation is initiated of the setting for the first valve to be set in accordance with the predetermined scheme.
19. A method for providing a system according to any preceding claim, wherein the valves are provided from a manufacturer or distributor with a flow gauge and a transmitter as a demountable add-on unit on the valve, wherein the unit is demounted after a flow balancing procedure and sent back to the manufacturer or distributor for recirculation with new valves.
20. A method according to claim 18, wherein the unit also comprises an electric actuator for automated valve setting.
