Sample Line Management In A Fluid Analyzer System

摘要

In a first mode, a monitoring system inputs humidified gas through at least a portion of a conduit. At least a portion of the water in the humidified gas adheres to the inner surface of the conduit, inhibiting contaminants in the gas sample from adhering to the inner surface. The water in the humidified gas may also push any contaminants adhered to the surface of the sample line back out the sample line. In a second mode, after previously passing the humidified gas through the conduit, the monitoring system controls a flow of a gas sample including the contaminants through the conduit to a gas analyzer. The one or more layer of water on the inner surface of the conduit prevents or reduces a buildup of undesirable contaminants on an inner surface of a conduit that conveys gas samples.

主权项

1. A method comprising:
receiving a first mode control signal indicating to operate in a first mode; in accordance with the first mode control signal, inputting humidified gas through at least a portion of a conduit to inhibit contaminants from adhering to an inner surface of the conduit through which a gas sample passes; receiving a second mode control signal indicating to operate in a second mode; and in accordance with the second mode control signal, controlling a flow of the gas sample including the contaminants from a source through the conduit to a gas analyzer.
