Rubicon's range of Sonaray™ flow meters - both Pipe and Flume - have been developed specifically with irrigation and municipal customers in mind.
Sonaray™ flow meters have taken standard transit time flow measurement technology to a new level, with the ability to measure very low flows (ie. velocities) and high flows in the one meter - and at the same time achieving high accuracy performance. Rubicon's Sonaray™ technology is subject to a number of patent applications.
The Sonaray™ flow meters typically come with cross-path sensing to reduce any requirements relating to upstream disturbance of flow and the need for symetrical velocity profiles.
All Sonaray™ flow meters are compatible with and can be directly integrated into Rubicon's gate or SCADA technology as well as Total Channel Control® solutions.
Rubicon has a number of products in its Sonaray™ range of flow meters
Rubicon also manufactures complete flume flow meters that can be inserted into a standard rectangular flume structures of box culverts. The Sonaray™ flume flow meter is a unique product and offers many advantages for open canal flow measurement applications.
The Sonaray™ flume flow meter is well suited to irrigation metering applications because:
An additional key feature of the Sonaray™ flume meter is the option for an integrated control gate - Rubicon's ValveGate™.
The ValveGate™ is completely contained within the flume meter structure and does not protrude outside the dimensions of the rectangular flume structure.
This allows the meter to be covered as with a box culvert application.
The ValveGate™ also maintains repeatable flow streamlines improving flow measurement ranges and avoiding limitations with hydraulic entry and exit conditions.
Rubicon offers standard pipe flow meters for a range of standard diameter pipes (eg, 300mm, 450mm, 600mm, 1000mm) with standard pipe couplings or flange interfaces.
Alternatively custom solutions can be developed or if preferred, acoustic sensors can be directly attached to in-situ pipes.
Sonaray™ pipe flow meters are available for pressure pipe (always full) or partially full pipe configurations.
Pressure pipe meters also have the option for triple redundancy metering to ensure continuous flow recording, should one of the three meters fail.
This is especially useful for meters that are required to meet high quality standards for recorded data.
Often these meters are in remote locations and require high servicing costs to ensure continuous recording and quality data.
These costs are significantly reduced with the Sonaray™ triple redundancy flow meter feature.
