Description
描述
ASME flow nozzles consist of an elliptical converging section and cylindrical throat section. This device has a greater overall pressure loss or operating cost in terms of head pressure than a subsonic Venturi but offers lower installation costs. Repeatability is better than an orifice meter but can be lower than that of a subsonic Venturi. Installation requirements are more stringent than for a subsonic Venturi but less than for an orifice meter. These meters are offered with either throat taps or pipe wall taps for pressure measurement.
ASME流量噴嘴包括一個橢圓形收縮段和圓筒形喉部截面。該裝置具有更高的總壓損失或經營成本在水頭壓力比音速文丘里但提供較低的安裝費用。重復性優于孔板流量計可低于亞音速文丘里。安裝要求亞音速文丘里但小于孔板流量計比更嚴格。這些米都提供了一種用于壓力測量的喉嚨水龍頭或管壁水龍頭。
