However, this device cannot detect the spray angle, intensity, and atomization effect of the nozzle with high accuracy, and cannot adjust the flow rate and pressure intensity of the air and water, thereby achieving the actual effect of the spray angle and atomization of the nozzle at different flow rates and pressures.
