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流量喷嘴包括一个椭圆形收缩段和圆筒形喉部截面。该装置具有更高的总压损失或经营成本在水头压力比音速文丘里但提供较低的安装费用。重复性优于孔板流量计可低于亚音速文丘里。安装要求亚音速文丘里但小于孔板流量计比更严格。这些米都提供了一种用于压力测量的喉咙水龙头或管壁水龙头。
