Flow Measurement
All Marksman models utilize an electromagnetic flow meter to measure flow rate of fertilizer or water/chemical mixture. Electromagnetic meters have no moving parts to lodge, stick or wear. They precisely measure any electrically conductive liquid.

​

Flow Control
Set the desired flow rate (GPH) for your application and Marksman will control the pump output to achieve the desired rate for the entire application. Changes in product viscosity due to temperature variation, changes in head height of tank, and other variables that change flow rate through traditional metering pumps, are a thing of the past. Marksman ensures you get the exact application you need.

​

Water Proportional Control

Marksman changes the chemical or fertilizer flow rate in response to changes in water flow such as corner swing-arm systems. Marksman ensures the correct rate is applied regardless of the swing arm position.

​

Shut Down Alarms

Off Rate Alarm – If tank runs dry or the strainer plugs up and Marksman cannot achieve the desired flow rate, Marksman will automatically shut down. Utilize Marksman pivot shut down relay kit to stop the pivot as well.

​

• Low and High Pressure Alarm – If injection pressure drops below the minimum pressure set point, Marksman will shut down. Eliminates hours of costly and harmful spills due to a broken hose.

• Water Pressure Low and High Pressure Alarm – With optional water pressure sensor, Marksman will shut down based on too low or too high of water pressure.

​

Batch Mode

Inject set number of gallons, then turn off.

​

Auto Run on Power Up

At power up, Marksman will automatically start pumping. Automatically resume injection after power shut down due to load control. Useful in drip irrigation to apply set batch size to each zone of system.
