The PikoMeter is an integrated canal turnout gate and meter that enables you to remotely deliver precisely-measured quantities of water.

Its all-in-one design makes remote automated control as simple as the installation.

Features and Benefits

The PikoMeter enables users to order their water online or over the phone, and the PikoMeter will automatically open and close at the right time to deliver the water. The PikoMeter’s control gate modulates to maintain a pre-set flow rate, even with fluctuating channel water levels. 

Sonaray® flow measurement technology uniquely enables the meter and control gate to be integrated into a single device. It means installation and maintenance costs are lower while measuring with unrivaled accuracy in harsh conditions. 

The option of integrated ultrasonic water level measurement enables the meter to measure even when partially-full. 

And no matter where you are, with a smartphone and SCADAConnect® software you can open and close the gate, read the meter, check historical data and monitor real-time performance.

 

The PikoMeter is ideal for
  1. Canal to pipe applications
  2. Cost-effective metering at smaller turnouts
  3. Turnouts in remote locations
  4. Measuring very low flow rates

 

Highlights
  1. Sonaray flow measurement accuracy of ±2.5%
  2. Solar-charged battery system
  3. Compact, lightweight construction for easy installation
  4. Integrated SCADA communication system

 

Control objective Gate action
Level control Moves to a desired set-point and stays there
Flow control Maintains a constant flow regardless of canal level


 

 
 
Low maintenance

The PikoMeter 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.

  1. High-quality components designed for long-life
  2. Built-in on-site diagnostic software and remote alerts
  3. Control and meter components easily accessible for visual inspection

 

Easy to install

PikoMeters are designed to mount to existing headwall 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-configured

 

Accurate flow measurement

Extensive independent laboratory and field testing of the ultrasonic array measurement technique has shown that accuracy is maintained in a wide range of conditions:

  1. Turbulent water
  2. Obstructions at the meter entry
  3. Water contaminants

Technologies


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

 

Sonaray® flow measurement technology

The PikoMeter employs Rubicon’s Sonaray cross-path ultrasonic flow measurement technology. Twenty transducers across five planes send and receive ultrasonic pulses to determine velocity by measuring the transit time taken for the pulses to travel between transducers. Cross-path measurement means that the control gate can be located directly downstream from the measurement area without affecting accuracy. The PikoMeter also has a downward facing transducer to determine whether or not the measurement cylinder is full.

 

 

Local control pedestal

Each PikoMeter installation includes a robust pedestal that provides power and control to the gate and is a secure, weatherproof housing for electronic components and batteries.

The pedestal also serves as a local user interface. A keypad and LCD display are located under the lockable pedestal lid, allowing farmers to monitor, or operators to control and troubleshoot on-site.  

 

 

Partially-full flow measurement

A MicronLevel® ultrasonic water level sensor can be optioned to provide a precise measure of canal water levels, plus it enables the PikoMeter to measure flow even when not completely full. The MicronLevel sits within the internal frame, or alternatively, a long-range MicronLevel Air sensor can be externally mounted nearby.

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 wire-rope (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 ±0.02in (0.5mm).

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.
