Abstract: A liquid product distribution network includes a keg distribution monitoring and reporting apparatus for operation in association with a tap handle flow monitoring and reporting apparatus. The keg distribution monitoring and reporting apparatus includes a radio transmitter device and sensing circuitry for sensing and communicating physical properties associating with the keg. A tap handle flow monitoring and reporting apparatus senses flow of a liquid through a tap includes a tap handle radio transmitter device for fitting within and protected by a tap handle and a low-energy consumption tap handle radio/processing module.
