ABSTRACT:
An apparatus and process for monitoring fluid flow through a nozzle is disclosed. A vibration sensor, such as an accelerometer, is mounted to a nozzle. The vibration output received from the sensor is then analyzed to determine whether or not the nozzle is operating properly. Through the present invention, information can be obtained regarding variations in flow rate, and/or variations in spray pattern and droplet size spectra. If the nozzle flow pulsates, the vibration sensor may also provide information regarding whether the nozzle is pulsating according to a desired frequency duty cycle or waveform.
