Abstract: A moisture provision and analyzer arrangement includes a conduit for obtaining a sample flow of natural gas, a moisture analyzer, and a bypass flow conduit. A main orifice is in fluid communication within the moisture provision and analyzer arrangement with flow proceeding to the moisture analyzer. A bypass orifice is located along the bypass flow conduit. The main orifice is sized and the flow provided to the moisture analyzer via the main orifice is at a pressure such that the flow provided to the moisture analyzer is at a critical flow condition and the bypass orifice is sized and the bypass flow is provided at a pressure such that the bypass flow is at a critical flow condition. Components in the moisture provision and analyzer arrangement are selected such that the critical flow rate through the main orifice and the critical flow rate through the bypass orifice are equal.
