Testing & calibration spray computers

The test equipment for testing and calibrating spray computers consist of a flow meter combined with a Bluetooth read out module. The flow values are transmitted over Bluetooth to a laptop/tablet and monitored by a dedicated app. The combination can be used to determinate precisely the real time application rate by way of measuring nozzle flow at the sprayer boom while driving over a predefined distance at a fixed speed. This equipment can also be used to test individual nozzle flow rates.

Testing equipment for spray computers

  • The measuring set-up and protocol fulfils the requirements set by ISO 5682-3 'Equipment for crop protection - Spraying equipment - Part 3: Test method for volume/hectare adjustment systems of agricultural hydraulic pressure sprayers‘
  • Based on time measurement and volume measurement over a predefined distance
  • Speed and volume/hectare rate are measured at the same time

Application

  • Calibrating and testing spray computers volume/ha rate and speed in field conditions
  • Determine volume/ha rate sprayers without spray computer
  • Testing flow rate of nozzles when mounted on the spray boom
