1. A liquid flow system for monitoring washing compliance comprising:

  • a sensor disposed near or on a liquid dispenser to generate a vibration signal;

    a modulator to modulate said vibration signal by amplification;

    a comparator to determine if the modulated signal exceeds a threshold value, wherein the threshold value identifies liquid flow through an output voltage; and

    a relay that is actuated using the output voltage.
