Abstract: A system, method and device for monitoring fluid dispensing are described. The method includes coupling a plurality of sensors to a valve of a fluid dispensing assembly, wherein the valve is configured to operate in either a first state or a second state to control fluid flow from the inlet to the outlet. A change of a state of the valve is detected from the first state to the second state from the second state back to the first state. The detected data from the detected sequence of triggering events, a time duration and a predetermined flow rate may be transmitted through a wireless transceiver, to one or both of an external user device and a remote central monitoring unit for a determination of a volume V of fluid being dispensed.

Abstract: A device, system, and method for tracking product inventory may include at least one sensor and at least one wireless communication device. The wireless communication may remain in a standby state until the sensor senses a particular condition, at which time the sensor may instruct the wireless device to transition to an operating state, transmit the sensed condition, and return to the standby state.
