Liquid level measuring device
View Patent ↗A liquid level sensing and reporting system for bar keepers is proposed, having a liquid level sensor in wireless communication with a remote computer having software algorithms for calculating and reporting volume. The sensor is substantially in the form of a liquor bottle spout, and includes a means for measuring the height of the liquid in a bottle, sensing inversion of the spout, and sending the data wirelessly to a receiver. The receiver is associated with the computer, and transmits the data to the computer which calculates liquor volumes based on the changing height of the liquid in a bottle from pre-pour to post-pour status. The software extrapolates this information to produce a variety of real-time beverage consumption reports, including error reports caused by over pours, under pours, and skimming.

13. The liquid measuring device of claim 1 wherein the inventory program calculates and presents volume change data in tandem with changing sensor data thereby providing volume change data in “real time.”
14. The liquid measuring device of claim 1 wherein the inventory program recognizes commonly mixed liquor combinations and proposes likely combinations to a user when receiving commonly combined liquor data from individual sensors.
15. The liquid measuring device of claim 1 wherein the inventory program detects data anomalies representing pour errors in tandem with changing sensor data, and provides individualized error reports to a user in “real time.”
16. The liquid measuring device of claim 1 wherein the inventory program stores inventory data for individual liquor types and generates a re-order alert at predetermined inventory levels based on sensor volume data.
17. The liquid measuring device of claim 1 wherein the inventory program interfaces with at least one point-of-sale register with which at least one sensor is associated.
18. The liquid measuring device of claim 17 wherein the inventory program correlates individual sensor data to mixed drink combination data, and suggests likely combinations to a bartender, thereby decreasing the likelihood of a point of sale error.
19. The liquid measuring device of claim 17 wherein the inventory program detects anomalies between sensor data and point of sale register data and produces an error report based on data anomalies.
20. The liquid measuring device of claim 19 wherein the inventory program generates time-based transaction histories associated with pour data and point of sale data.
21. The liquid measuring device of claim 1 wherein users may switch from real-time transaction monitoring to transaction history viewing without affecting ongoing data collection.
22. The liquid measuring device of claim 2 wherein the at least one spout transmits activation data upon the occurrence of a predetermined activation event.
