Near Intersection of I-35 & I-90 Southern Mn. | Yes, your Ag Leader system can show various pressures on screen. Three readings are possible. This requires the purchase and installation of expensive pressure transducers and the cable(s) to connect them to the Liquid Product Control module. The transducers need to be calibrated.
However, I have used two of these systems for several years and have never installed any electronic pressure transducers although I could. I rely on simple old school direct reading pressure gauges both on the planter and sprayer.
With our planter setup, the spray pump is mounted on the tractor on the right tank of a pair of SideQuest tanks. This allowed me to install a common pressure gauge on the feed line back to the planter. Since this is in front of the right tire, it is easy to view out the lower front right window.
Our Hagie has the OEM boom pressure on the front mounted boom itself in plain sight as well as the ability to visually "see" the position of the agitation valve setting out the side window. The agitation valve is controlled by a momentary toggle switch. We can observe the position of the valve pointer to observe the amount of agitation allowed.
I have seen setups where a common gauge is connected using a piece of 1/4" tubing so the gauge can be mounted in clear view of the operator. I saw a gauge one time that had the numbers written in reverse so the gauge could easily be read in a mirror. Actually even though a common gauge would be a bit difficult to read in a mirror, it would still probably be understandable
Since a system using a Liquid Product Control Module is completely flow based, it makes no decisions based on pressure. The ability to observe the pressure is really just for the operator's piece of mind that all is well. This can be consulted from time to time but is not used on a continuous basis. I believe a pressure gauge is important but not to the degree that I would spend money on the electronic approach.
Others obviously feel that having an onscreen pressure readout is important.
It appears that the newer Ag Leader systems involving the L2 module may involve decisions based on pressure so the electronic pressures sensors may be necessary then. It would then be possible to set low limits etc. based on pressure. Setting a low limit can prevent a poor pattern or tip check off when low ground speeds are necessary to avoid obstacles such as powerline poles, waterways etc.
Low limits can be set with the Liquid Product Control Module based on a flow minimum. The low limit value can be determined by Trial & Error or consulting a tip chart. A tip chart will indicate the flow/minute per tip at various pressures. Select the minimum pressure you wish to maintain or stay above and note the flow rate for a single tip. Multiply that value by the total number of tips on your sprayer. This will give you the minimum flow needed to maintain at least that pressure.
As always, proper tips are important. No amount of electronic wizardry can make up for incorrect tips.
