Apparatus for determining the concentration profiles of liquid or gaseous substances along a given path
First Claim
1. An apparatus for determining a concentration profile of a fluid substance along a given path, comprising:
- a line laid along a given path, said line being adapted to allow fluid substances to penetrate into an interior thereof;
a sensor sensitive to the fluid substances communicating with said line;
a column of test medium filling said line;
a pump for forcing said column of the test medium through said line at chronological intervals and for moving said column of the test medium past said sensor;
a first closure between said sensor and said line;
a second closure incorporated into said line for maintaining said column of the test medium substantially stationary in a position of repose; and
a device for automatically opening said second closure when a pressure value dropping in said line exceeds or undershoots a given threshold value.

Abstract
The apparatus enables accurate determination of concentration profiles of liquid or gaseous substances along a given path. A partially permeable line segment is laid along the route and the substances to be detected are allowed to penetrate into its interior. The line is filled with a test medium, and the column of the test medium is forced through the line at chronological intervals and moved past a sensor that is sensitive to the substances. A first closure is incorporated between the sensor and the line, and one or more closures are incorporated into the line to maintain the column of test medium substantially stationary in a position of repose of the system.
