## OrificeButIndex Description
OrificeButIndex helps you pick the right orifice plate beta ratio—fast and with clear guidance. Enter pipe size, flow min/max, fluid data, and your DP limit; the app shows how beta affects pressure drop, reading error, and usable range. See simple plots of DP vs. flow and a quick Reynolds check so you know when results are solid or shaky. Get plain-language tips when you’re near risky zones (very low Re, very high beta, or likely fouling). Compare a few beta options side-by-side to balance accuracy, head loss, and dirt tolerance. Use smart defaults to speed through early design, then fine-tune as you narrow choices. Export a short sizing note for handover or review. Perfect for quick checks before sending data to vendors or running full meter.
