Features and Benefits

The SlipMeter can be remotely pre-set to turn on and off automatically to deliver a constant and accurately measured flow rate and volume. This means you can provide a great service day or night, even when supply canal levels are fluctuating.

And the all-in-one design means everything – drive system, motor control, ultrasonic measurement, power supply, local control keypad and telemetry – functions as a single unit. There are no installation problems or incompatibilities, it simply works.

The SlipMeter’s ability to measure accurately at high and very low flow rates means it is suitable for all crop types. And the extremely low head loss means that command is not compromised even when very little head is available.

It has been designed to be installed in existing structures without costly civil work, by simply sliding into a frame that is fixed to the existing structure.

The SlipMeter is ideal for

1. Turnouts requiring very low head loss and/or high accuracy
2. Situations where water level fluctuations mean the meter is frequently partially full
3. Minimizing expenditure on civil infrastructure
4. Situations where is high turbulence, debris or other contaminants
5. Remote locations that require controlled flow rates

Highlights

1. Sonaray flow measurement accuracy of ±2.5%*
2. Exceeds California SBx7-7 requirements
3. Solar-charged battery system or AC line power
4. SCADA ready communication system – can be integrated to many SCADA platforms
5. Partially-full measurement when fitted with MicronLevel™ sensor

Control capabilities

The SlipMeter's built-in software provides the following control possibilities:
 

Local control pedestal

Each SlipMeter 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 lockable pedestal lid, allowing farmers to monitor, or operators to control and troubleshoot on-site.

Low maintenance

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

1. Level sensors are easily removed during in-field servicing
2. Seals can be replaced
3. On-site diagnostics built into the software
4. Service can be done by local Rubicon field technicians or authorized/trained independent local integrators

Easy to install

SlipMeters 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

Existing manual gate	Replaced with SlipMeter

Independently tested flow measurement accuracy

The SlipMeter’s flow measurement accuracy has been independently verified under a wide range of conditions and has demonstrated compliance with California's SBX7-7 legislation.

Technologies

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

Sonaray^® flow measurement

The SlipMeter employs Sonaray acoustic array technology. The acoustic 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 non-uniform velocity distributions caused by garbage or other debris.

		Eight horizontal planes sample the velocity distribution passing through the meter (side view)
		Each measurement plane implements crossed-path transit time ultrasonics to sample the entire velocity field in that plane (plan view of measurement plane)
		The horizontal velocity distributions are then integrated vertically to construct the three dimensional flow velocity distribution (side view)

High-strength FormiPanel™ construction The SlipMeter features FormiPanel™, Rubicon’s high-strength construction method that uses techniques adopted from the aerospace and marine industries. The gate panel and meter assembly is made from 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 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 ±0.5mm (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, fusing and the pedestal user interface.
