A liquid supply device, particularly for gluing machines, coating machines, paper moistening machines and printing machines. The anode assembly includes a drive member arranged and disposed to provide oscillatory motion to the target assembly and a target surface that is configured to remain at a substantially fixed distance from a cathode assembly during oscillatory motion. The system then configures the database to send the notification about the specified event-type to the specified list of recipients in the specified format via the specified protocol.
