Abstract:
An emission prevention system for use on an open-ended line includes an end-cap and a proximity sensor. The proximity sensor is preferably configured to detect a change in the extent of engagement between the end-cap and the open-ended line. A method of monitoring the engagement of the end-cap and the open-ended line includes the steps of measuring the engagement between the end-cap and the open-ended line with a proximity sensor, producing a position signal representative of the engagement between the end-cap and the open-ended line and transmitting the position signal to an operator terminal. A monitoring network may be established by monitoring a plurality of emission prevention systems.
