An apparatus for the continuous remote measurement of the flowrate of water in bulkhead-holder openings for irrigation, characterised in that it comprises a measuring instrument installed at a distance relative to a lower crossbeam which acts as a bulkhead in an opening of an irrigation channel; the apparatus comprises vertical uprights integral with the crossbeam and a transmitter device; the apparatus can be installed at an opening of an irrigation channel so that the vertical uprights can be made to slide inside bulkhead-holder grooves provided in the sides of the opening; the apparatus allows the detection of data including at least the level of the surface of the water at the opening and the transmission of said data to a remote location.

An arrangement for controlling and measuring flow. The arrangement includes a fluid control barrier and a flow-measuring apparatus upstream of the fluid control barrier. The fluid control barrier includes a pair of plates for opening and closing a pipe, and the plates are movable towards a center line of the pipe to open the pipe and produce a symmetrical flow profile for the flow-measuring apparatus.

A riser for a surface irrigation system, the riser having a housing and an outlet valve. The 5 housing has an open upper portion and an outlet defining an orifice through which irrigation fluid is to be discharged. The valve includes an upper closure, a valve member, and an actuating lever. The upper closure is securable to the riser for sealing the open upper portion. The valve member is coupled to the closure and mountable within a flow path of the fluid, the valve member operable for opening and closing the valve, and configured to 10 seat against a valve seat of the housing, and on an upstream side of the orifice, whereby the pressure of fluid within the valve urges the valve member against the seat when the valve is closed. The pivotable actuating lever having one end extending through the orifice and coupled to the valve member, an intermediate fulcrum, and an operable end for operating the valve member to open and close the valve.

The present invention relates to a method for providing watering or non-watering of a specific area of soil through a first plurality of irrigation valves (42). Specific irrigation parameters are measured at the specific area of soil through a second plurality of field sensors (54). A controller unit (30) is interconnected to a third plurality of control units (18). Each control unit is connected to a specific irrigation valve and/or a specific field sensor. A type declaration providing communication under a second communication protocol is transmitted from the controller unit to the third plurality of control units using a first communications protocol. A second set of instructions are transmitted from the controller unit to the third plurality of control units using a second communications protocol. A first set of instructions are transmitted from the controller unit to the third plurality of control units using the first communications protocol.
