Abstract: The present disclosure discloses a system for measuring a charge-to-mass ratio of an electrostatic atomization nozzle and a measurement method using the same. The system includes an electrostatic atomization nozzle, an upper cylinder, a lower cylinder, an ammeter, a liquid level tube, an ultrasonic level meter, a water storage tank, and a liquid pump. The electrostatic atomization nozzle, the upper cylinder, and the lower cylinder are sequentially connected from top to bottom. The ammeter is connected to the lower-cylinder flange. The liquid level tube is communicated with the lower cylinder. The ultrasonic level meter is mounted on an upper end of the liquid level tube. The water storage tank is located below a lower-cylinder water outlet pipe. The liquid pump can deliver a liquid in the water storage tank to the electrostatic atomization nozzle. Measurement data of the ammeter is acquired and processed by a computer in real time.
