FlumeGate(TM) FlumeGate(TM) FlumeGate(TM) FlumeGate(TM) FlumeGate(TM)

The FlumeGate is a combined flow measurement and control gate designed to regulate flow in open canals.

Accurate flow measurement, precise flow control, power supply and radio telecommunications are fully integrated in a single device. 

Features and Benefits


The FlumeGate can be operated as a stand-alone unit, or can coordinate with other gates along the canal to optimize the whole network’s flow. In free-flow or submerged conditions, flow is calculated from the gate’s own measurements of upstream water level, downstream water level and gate position.

It can be managed and monitored on-site or operated remotely when connected to a SCADA network.

 

The FlumeGate is ideal for
  1. Headgates or check structures requiring low headloss and high accuracy
  2. Gate modernization projects (more cost-effective than automating an existing gate)
  3. Remote locations without AC power
  4. Highly corrosive environments including salt water
  5. Maintaining canal diversions or upstream water levels
  6. Measuring flow in canal-to-siphon applications
     
Highlights
  1. Overshot design for better water level control
  2. Flow calculations and control software built-in
  3. Ultrasonic water level measurement
  4. Solar-charged battery system or AC line power
  5. SCADA ready communication system
  6. Robust high duty cycle operation
  7. Standard sizes from 2' to 10'
  8. Optional walkways with handrails for staff safety

FlumeGate control capabilities

The FlumeGate automatically controls the flow of water by varying the gate position based on a desired set-point or on irrigation demand as shown in the table below.
 

Control objective

Gate action

Local Position Moves to a desired set-point and stays there
Flow Maintains a constant flow regardless of upstream or downstream levels
Upstream level Maintains a desired level in the pool immediately upstream
Downstream level
Maintains a desired level in the pool immediately downstream
Network* Demand Changes the flow to match measured outflow from the network below the pool while maintaining a stable downstream water level
Supply Changes the flow to match the flow supplied from the network above the gate while maintaining a stable upstream water level

* Network control is only available when used with other Rubicon gates and Rubicon’s NeuroFlo® network control software.
 

Local control pedestal

Each FlumeGate installation includes a robust pedestal that provides power and control to the gate and is a secure, weather proof housing for electronic components and batteries. The pedestal also serves as a local user interface. A keypad and LCD display are located under the pedestal lid, allowing farmers to monitor, or operators to control and troubleshoot on-site.


Low maintenance

The FlumeGate’s modular design allows it to be maintained in the field with minimal tools, training, and easily replaceable parts.
 

  1. Retractable level sensors allow for easy in-field servicing
  2. Seals can be replaced
  3. On-site diagnostics
  4. Service can be done by local Rubicon field technicians or authorized/trained independent local integrators

Easy to install

Rubicon’s FlumeGate products are designed to retrofit to existing check type regulating structures as well as purpose built emplacements significantly reducing costs associated with civil work.
 

  1. Installed and operational in two days during irrigation or off-season
  2. Factory calibrated and pre-commissioned

Technologies


The FlumeGate uses technologies developed by Rubicon which are common across TCC® products:

High-strength FormiPanel™ construction

FormiPanel is Rubicon’s high-strength gate leaf construction that uses techniques adopted from the aerospace and marine industries.

The gate panel assembly is a laminate construction that utilizes high strength industrial adhesives to bond structural grade aluminum extrusions and skin plates to a synthetic core material. The result is strong, lightweight, and corrosion resistant.

CableDrive™ and SolarDrive® gate control technology

CableDrive is Rubicon’s actuation system designed to provide precision gate position accuracy and repeatability in harsh environments. The drive is a wirerope (cable) and drum mechanism that provides positive drive in both the raise and lower directions. It is designed for high duty cycle operation and provides precise gate positioning to within ±0.5mm (±0.02in).

The drive is managed by Rubicon’s SolarDrive technology – a purpose built integrated circuit board that manages gate positioning, solar power regulation, battery charge and the pedestal user interface.

 

MicronLevel® measurement

The FlumeGate calculates flow using measurements of upstream water level, downstream water level and gate position, achieving in-field, independently verified measurement accuracy of ±2.5%**. This accuracy is attributed to its unique design and precision manufacture.

Rubicon’s MicronLevel water level measurement sensors are housed within the internal frame. A water-tight seal separates the upstream and downstream sensors.

  1. Unique, integrated stilling wells unaffected by surrounding objects, debris, foam, silt or other contaminants 
  2. Self-calibrates on every reading to eliminate drift in speed of sound variations due to changes in temperature or humidity
  3. Specifically designed for use in harsh irrigation canal environments

**Accuracy of FG-M-626-620 and FG-1050-674 models verified by Manly Hydraulics Laboratory, January and August 2005
