Row to Row Accuracy

Liquid Systems’ engineered approach is all about equipment that delivers a multitude of liquid inputs with “Row to Row, Second by Second Accuracy.” This accuracy and even distribution is critical for crop protection success.

GRAPHS BELOW show that our customers can be confident that every row of their crop will receive the target liquid application rate:

Coefficinet of Variation (COV) Graphs

Independently conducted testing by a US customer has demonstrated that Liquid Systems (SA) Stacker Distribution System has superior performance against a commonly used variable flow system. The graphs compare the Coefficient of Variation (COV) of the two systems:

  • The first chart is at 12” spacings. The second chart is at 30” spacings.
  • COV is a measure of how evenly liquid is applied across the bar. The lower the COV the more even the distribution.
  • The results demonstrate an extreme contrast in accuracy between the two, especially at lower rates. The Stacker Distribution System provides a far superior performance with a verified average COV of 4.1% over an operating pressure range of 0.3bar – 7.0bar (4.5psi – 100psi) across a wide range of application rates.

Accurate in-furrow delivery is essential to reduce input costs to the farmer while maximising the benefits of their inputs.

The VIDEO BELOW shows the normal operation of our systems, highlighting some manual steps you need to follow. It also shows where the flow goes and explains why.

Correct liquid flow is critical for the farmer for a number of reasons: • One, they need the product to maintain its physical integrity to maintain performance. • Two, they need the product to be applied at the correct target rate’s with even & accurate placement to ensure minimal product waste.
