Gas line leakage monitor for beverage dispensing system preventing unintended environmental discharge

A method for monitoring gas line leakage monitor in a beverage dispensing system to prevent unintended environmental discharge, the method comprising the steps of

• A) detecting when gas is flowing through the system by providing an inline gas line leakage monitor:
• a gas inlet configured to be coupled to the source of gas, a gas outlet configured to be coupled to the dispensing portions of the dispensing system, an in-line flow sensor in the monitor positioned in-line between the gas inlet and the gas outlet and configured to detect when gas is flowing through the monitor from the gas inlet and through the flow sensor to the gas outlet, a timer coupled to the flow sensor and configured to track the amount of time that the flow sensor detects at least each episode of un-interrupted flow of gas from the gas inlet through the monitor and through the flow sensor to the gas outlet;
• and a shut-off valve positioned in-line between the gas inlet and the gas outlet and coupled to the timer and configured to stop the flow of gas through the monitor and to the dispensing portions of the dispensing system when the timer indicates that an episode of un-interrupted flow of gas through the monitor meets or exceeds a pre-set threshold, and a reset for the system including resetting the timer and the shut-off valve by opening the shut-off valve;
• B) tracking the amount of time for at least each episode of un-interrupted flow of gas detected in step A with the in-line monitor;
• C) Stopping the flow of gas through the system through activation of the shutoff when an episode of un-interrupted flow of gas through the system meets or exceeds a pre-set threshold;
• and
• D) resetting the system via the system reset to allow further flow of gas through the system for subsequent operation.

An in-line CO2 line leakage monitor for CO2 dispensing system having normal intermittent use with the monitor configured to prevent unintended environmental discharge of CO2, the monitor comprising:

• a CO2 inlet configured to be coupled to the source of CO2;
• a CO2 outlet configured to be coupled to the dispensing portions of the CO2 dispensing system;
• an in-line flow sensor in the monitor positioned in-line between the CO2 inlet and the CO2 outlet and configured to detect when CO2 is flowing from the CO2 inlet through the monitor and through the flow sensor to the CO2 outlet;
• a timer coupled to the in-line flow sensor and configured to track the amount of time that the in-line flow sensor detects at least each episode of un-interrupted flow of CO2 through the monitor;
• a shut-off valve coupled to the timer and configured to stop the flow of CO2 from the CO2 inlet through the monitor and through the flow sensor to the CO2 outlet and to the dispensing portions of the CO2 dispensing system when the timer indicates that an episode of un-interrupted flow of CO2 through the monitor meets or exceeds a pre-set threshold;
• and
• a manual reset for the system including resetting the timer and the shut-off valve by opening the shut-off valve.
