Flow measurement accuracy

Rubicon specifies SlipMeter™ flow measurement accuracy of ±2.5% in the laboratory and ±5% in the field

The SlipMeter's™ accuracy has been verified by independent laboratory and field testing.

Laboratory testing found the 600mm SlipMeter™ was accurate under normal operating conditions to better than ±1.5% across a flow range of 0.4 to 15.5cfs (1 to 38 ML/d). Download report
Field testing found the 600mm SlipMeter™ was consistently accurate to within ±2% of the reference meter across a flow range of 1cfs to 15cfs (2.4 ML/d to 36.7 ML/d). Download report

Sonaray™ Acoustic Array Flow Measurement

The SlipMeter™ features Sonaray™ acoustic array flow measurement technology, which Rubicon developed to provide accurate and reliable flow measurement under the harsh conditions experienced in the irrigation industry.

A development of ultrasonic flow measurement, Sonaray™ acoustic array flow measurement is a new innovation developed by Rubicon. It employs concepts found in medical imaging in which an array of acoustic transducers is used to provide a three-dimensional image of a medium.

This technology enables measurement of very low velocities, meaning that both high and low flows can be accurately measured in a single meter.

Additionally it provides accurate flow measurement even in the presence of severe flow disturbances.
