Abstract:
1. An inline gas line leakage monitor for gas dispensing system configured to prevent unintended environmental discharge, the monitor comprising: 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 and 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; 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.
