Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A monitoring system for monitoring the filling of containers from a tank station; at least one fluid product connecting line for connecting the tank station to a container being filled with a fluid product through said at least one fluid product connecting line; a shut-off element for said at least one fluid product connecting line; an electrical measuring means in said at least one fluid product connecting line for determining the maximum permissible level of fluid product being filled into the container; said at least one connecting line being an electrically conductive connecting line connected through an electrically insulated connection at one end to the container, and connected through an electrically insulated connection at the opposite end to the tank station; and electrical monitoring circuit means for monitoring the electrical impedance of a series electrical circuit of said measuring means and said at least one fluid product connecting line, which characterizes the filling condition of the container and the condition of the connections between the tank station and the container.
Claim 2
Dependent Claim
170 words
A monitoring system for monitoring the filling of containers from a tank station; at least one fluid product connecting line for connecting the tank station to a container being filled with a fluid product through said at least one fluid product connecting line; a shut-off element for said at least one fluid product connecting line; an electrical measuring means in said at least one fluid product connecting line for determining the maximum permissible level of fluid product being filled into the container; said at least one connecting line being an electrically conductive connecting line connected through an electrically insulated connection at one end to the container, and connected through an electrically insulated connection at the opposite end to the tank station; and electrical monitoring circuit means for monitoring the electrical impedance of a series electrical circuit of said measuring means and said at least one fluid product connecting line, which characterizes the filling condition of the container and the condition of the connections between the tank station and the container.
Claim 3
Dependent Claim
27 words
A monitoring system as claimed in claim 1, wherein said measuring means comprises a cold-conductor system; and said monitoring circuit means includes at least one voltage source.
Claim 4
Dependent Claim
28 words
A monitoring system as claimed in claim 1, each electrically insulated connection including an impedance bridging over the electrically insulated connection for conducting off and dissipating electrostatic charges.
Claim 5
Dependent Claim
31 words
A monitoring system as claimed in claim 1, wherein said tank station further comprises a second fluid connecting line for venting exhaust gas from the container during filling of the container.
Claim 6
Dependent Claim
42 words
A monitoring system as claimed in claim 1, wherein a control device is coupled between said monitoring circuit means and said shut-off element, which is actuated by said control device in dependence upon the measured electrical impedance of said series electrical circuit.
