Dosistar Grainy LV

For flow control of DC pumps with higher power

The DOSISTAR GRAINY LV is intended for stationary or mobile use operation on 12/24V battery systems.Pumps with DC motors up to 480W can be controlled. The current throughput of the pump (l/h) is measured with an external flow meter and then adjusting the flow setpoint. Operating modes are continuous flow control and batch dosing.

Area of application

  • Flow control of liquids
  • Batch dosage with remote control function
  • Quantity logging
  • Feed preservation
  • Grain preservation
