One embodiment of a system for determining a wellbore parameter includes a pulse generator positioned in fluid communication with a wellbore such that a fluid can flow from the wellbore through the pulse generator, wherein the pulse generator selectively releases the fluid to flow through the pulse generator causing pressure pulses in the wellbore; a receiver in operational connection with the wellbore, the receiver detecting the pressure pulses; and a controller in functional connection with the receiver, the controller determining a wellbore parameter from receipt of a signal from the receiver in response to the detected pressure pulses.
