NO supply device suitable for land or air transport

Abstract

Title of the Invention: NO Supply Apparatus Adapted for Ground or Air Transport. The invention relates to an apparatus for delivering (1) a gas containing NO, comprising an internal gas circuit (200) with flow control means (220, 230, 240) for controlling the gas flow, in particular a proportional solenoid valve (220) and a flow measurement device (230). Pilot means (210) cooperate with the flow control means (220, 230, 240) to allow, prohibit, or adjust the gas flow within the gas circuit (200). The flow measurement device (230) includes a bidirectional flow sensor configured to perform positive and negative flow measurements of the NO-containing gas flow circulating in the gas circuit (200), and to provide said flow measurements to the pilot means (210). Installation for supplying a gas containing NO (100) comprising such an NO delivery apparatus (1). Figure from the summary: Figure 2
