Nozzle flow rate test bench

The nozzle flow rate test benches are used for a precise measurement of the flow rate of hydraulic nozzles at a given pressure. A stationary as well as a mobile test bench is available.

Stationary nozzle test bench

  • The measuring set-up and protocol fulfils the requirements set by ISO 5682-1 'Equipment for crop protection - Spraying equipment - Part 1: Test methods for sprayer nozzles‘
  • Based on time measurement and weighing of sprayed water
  • Anti-mist tubes to avoid losses
  • Weighing accuracy ± 1 g on a minimum volume of 7000g (=+/-0.015%)
  • Pressure accuracy ±  0.01 bar

Mobile nozzle test bench

  • Flow rate measurement by means of an inductive flow meter
  • Flow meter calibrated with an accuracy of +/-0.15%
  • Pressure accuracy 0.01 bar

Application

  • Stationary nozzle test bench:
    • Very precise measurement of the flow rate of hydraulic nozzles
    • Reference nozzles to validate/calibrate mobile nozzle test benches
    • Quality control of new nozzles with respect to the nominal flow rate
  • Mobile nozzle test bench:
    • Quick and precise measurement of the flow rate of large amount of hydraulic nozzles
    • Inspection of sprayers
