When a hydrant is activated, the electronic module performs at least one of the following functions: stores activation time data, records sound data, records image data, turns on a signaling device, determines possible flow rate by counting the number of turns the operating nut has been turned, records elapsed time since hydrant activation, estimates consumption based on time data and possible flow rate data, transmits activation data to a remove receiver. Embodiments of the smart monitor also include a receiver configured for receiving a signal from remote transmitter for activating the signaling device.
