Fluid Sampling System
US Patent:
6241950, Jun 5, 2001
Filed:
Feb 13, 1998
Appl. No.:
9/023846
Inventors:
Robert Veelenturf - Norfolk MA
David W. Bearg - Concord MA
David W. Bearg - Concord MA
Assignee:
Airxpert Systems, Inc. - Lexington MA
International Classification:
B01L 1100
US Classification:
422103
Abstract:
A fluid sampling device including a manifold having inputs, common purge and sampling pathways, valves disposed to couple and decouple a first set of the inputs to the common purge pathway and a second set of the inputs to the common sampling pathway, and a differential sensor coupled to the pathways. A controller connected to the valves produces control signals that enable the valves to couple and decouple the inputs to the common sensor and purge pathways. In addition, a method for operating a fluid sampling system that is connected to a set of sample zones that includes the steps of sampling fluid from first and second sample zones in respective first and second sample locations, isolating third and fourth sample zones from the first and second sample locations, and measuring a differential parameter across the sample locations.
