FlumeMeter(TM) FlumeMeter(TM) FlumeMeter(TM)

The FlumeMeter is a ground-breaking flow meter specifically designed for open canals.

Its all-in-one design makes it simple to install, almost maintenance-free and provides accurate and reliable flow measurement even in turbulent environments.

Features and Benefits

All-in-one means everything has been designed – ultrasonic measurement, power supply, local control keypad and telemetry – to function as one single unit. There are no integration problems or incompatibilities, it simply works.

Unlike traditional meters, the FlumeMeter can measure even when partially full, has extremely low head loss and never requires calibration. This gives life-long confidence and almost no ongoing maintenance costs.

The FlumeMeter uses Rubicon’s unique Sonaray® technology which is unaffected by turbulence and so does not require straight lengths of pipe or canal upstream or downstream. This means it can be installed in existing structures without costly civil work and in structures where other meters just can’t be installed.

Even installation is simplified: just slide into a frame that is fixed to the existing structure, even onto a cover over an existing control gate, which makes upgrading existing sites a breeze.

Simple to manage, the FlumeMeter can be read on-site or remotely when connected to any Modbus, DNP-3 or MDLC compatible SCADA network including Rubicon’s SCADAConnect® system.
 

The FlumeMeter is an ideal solution....
  1. When very low flow rates need to be measured
  2. When water level fluctuations mean the meter is frequently partially full
  3. To minimize expenditure on civil infrastructure
  4. Where there is high turbulence, debris or other contaminants
  5. For remote locations
     
Highights
  1. Sonaray flow measurement accuracy of ±2.5%
  2. Exceeds California SBx7-7 requirements
  3. Can be mounted over existing turnout gates
  4. Solar-charged battery system
  5. No calibration needed
  6. Reads accurately when partially full when fitted with MicronLevel™ sensor
  7. No moving parts to catch debris

 

Low maintenance

The FlumeMeter requires minimal maintenance. Comprehensive error detection and on-site diagnostics are built into the meter software.

Factory pre-calibrated, its digital measurement does not drift or require periodic recalibration to maintain accuracy.
 

Easy to install

Using a slide-in frame, FlumeMeters are designed to retrofit upstream of existing turnout gates to significantly reduce costs associated with civil work. They can also be mounted to purpose built emplacements.

In most cases it can be installed and operational in two days; during irrigation or the off-season.

Technologies


The FlumeMeter uses core technologies which are common across TCC® products:


Sonaray® flow measurement

The FlumeMeter employs Rubicon's Sonaray ultrasonic array flow measurement technology. The ultrasonic array principle maps the velocity profile by using multiple transecting paths to provide an accurate representation of the velocity distribution within the meter box. This technique measures across the entire velocity field within the meter box and is resistant to swirl, or other nonuniform velocity distributions caused by garbage or other debris.

It also eliminates the need for flow profile calibrations that are required for single-point, single-path and doppler flow meters.
 

  Eight horizontal planes sample the velocity distribution passing through the meter
 

Each measurement plane implements crossed-path transit time acoustics to sample the entire velocity field in that plane
  The horizontal velocity distributions are then integrated vertically to construct the three dimensional flow velocity distribution

 

SCADAConnect® remote management 

The FlumeMeter can be managed remotely with Rubicon’s SCADAConnect Live software. This takes the form of a web page which allows authorized users to remotely view real-time and historical flow information and configure alarms that can be sent via text message to nominated cell phones.

 

 

 

SolarDrive® meter management technology

The meter is managed by Rubicon’s SolarDrive® technology – purpose built integrated circuitry that manages solar power regulation, battery charge and it provides data and management tools via the user interface.

Flows are measured with up to one second resolution and are stored with volumetric usage records in internal memory. Data recording annual water usage can be uploaded via the internal serial port or remotely via a SCADA system.
