SureFire introduced the Sentinel™ Liquid Row Monitor in 2015 to bring liquid row monitoring into your existing in-cab display. In 2016, the Sentinel™ ISOBUS had a successful launch. Since that time, we have gained valuable information and feedback that will allow us to bring new and intuitive software enhancements this season with more coming in the near future.
Row-To-Row Accuracy that is Second-to-None
During Planting 2018, SureFire studied the row-to-row accuracy of LiquiShift combined with Metering Tube, planting 3000 acres of Irrigated and Dry Land corn with a 24 Row, 30″ planter. As our lab and engineering tests have shown previously, the accuracy is second-to-none. The farmer’s prescription applied from 10 to 40 GPA. SureFire analyzed over 50,000 data points logged from the Sentinel™ Liquid Row Monitor showing that the Row-to-Row CV (Coefficient of Variance) is less than 4.6% over 95% of the time. The average CV is just 3.9%.
This large scale on-farm test confirms you will not find a more accurate system for your application needs!
In our 2018 field testing, Sentinel™ identified one row of the 24 Row Planter that was consistently 17%-19% lower than the other rows. The restriction was a slight kink in the hose at the pivot point of the single disc fertilizer opener. Without Sentinel™, the farmer would not have known of this significant reduction in rate.
What is the potential cost of not knowing?
Total Acres Planted = 3,000
Acres Planted by 1 Row = 125
Yield Goal of 140 bushes/ acre
Lost Yield on Restricted Flow (140 x .19) = 26.6
Total Bushels Lost (26.6 x 125) = 3,325
Lost Revenue (3,325 x 3.70) = $12,302
Cost of Sentinel™ Liquid Row Monitor for 24 Row Planter – $11,790
No Moving Parts
Sentinel™ utilizes SureFire’s E-Mag Flow Meter Technology on every row. These flow meters are accurate without the need for calibration and have no moving parts. Other row monitoring systems are available – all of them use a mechanical meter which is subject to plugging and lodging. With Sentinel™, just a 20 Mesh Strainer is needed to “get out the big chunks!”
20 Mesh – That’s all you need!
Nearly all SureFire systems, including Sentinel™, only require a 20 Mesh Strainer. A 20 mesh screen has 385% larger passageway size and 48% more open area than an 80 mesh screen. If you are tired of cleaning filters and unplugging orifices, SureFire has a system for you.
The Sentinel™ system allows in cab monitoring of the fertilizer flow to every row of a planter or applicator. This replaces the floating ball flow monitor with an in cab display and alarm to immediately alert the operator when the flow for any row is above or below the intended rate. Whether it is a plugged row or a leak, the operator will know immediately. This will nearly eliminate a crop planted without the proper fertilizer or pesticide.
- Much more than a blockage monitor, Sentinel™ also lets you know when flow is slightly reduced, not just completely blocked.
- Sentinel™ works great for prescription application. Sentinel’s auto-rate feature measures and calculates the average rate of all rows and identifies rows under or over this variable prescription rate.
- Flows are displayed in both gallons per minute and gallons per acre to easily understand system performance.
- Audio alarm alerts the operator within seconds when a row is under or over applying.
- Independent set points for % over or % under rate.
LiquiShift® integration with Sentinel™ ISO
The SureFire LiquiShift® is fully integrated with the Sentinel™ ISO controller. This feature allows you to monitor the system pressure and adjust the pressure shift points for more customization options. This combination also allows you to manually switch between the two metering tubes from the cab. On screen information allows you to monitor the pump duty cycle and visually see which metering tube is currently being used.
