暗桿針閥

尺寸為150 mm的流量計也可配備用于特殊應用的非升桿式針閥。這種15圈的計量閥具有優越的流量控制，特別適用于色譜分析應用。滑動錐形針機構實際上消除了由于流體中的異物而引起的粘附或堆積，而不會改變或鋸齒狀的流速。

加壓系統屏蔽

這些轉子流量計，帶有精密鉆孔的硼硅酸鹽玻璃計量管，完全可以防止破裂。白色不透明的后擋板提供了背景，以幫助識別浮動位置。

面板安裝設計

這些轉子流量計配有水平端口和NPT螺紋，便于面板安裝。端口有外螺紋，并配有面板固定螺母。不需要額外的安裝硬件。只需鉆兩個孔，間距為114 mm（4.500”）（中心到中心），用于65 mm裝置，間距為224 mm（8.813”）（中心到中心），用于150 mm裝置。每個孔的直徑應為16 mm（5/8”）。

Easy-to-Read Scale Design

Special Dimensions for Interchangeability

The OMEGA? precision variablearea rotameters can measure flows of air, water, and gases, with up to ±2% FS accuracy and 0.25% FS repeatability (models ending in "07" or "45" have ±5% FS accuracy). These units feature an easy-to-read millimeter scale and come with correlation charts for air and water. The scale is fused on the metering tube in 1 mm (3/32") increments, which enables a user to read the flow rate with the highest accuracy.

The scale design, in which a vertical line runs through the length of the scale and intersects the horizontal scale divisions, reduces parallax and eye fatigue, thus ensuring highaccuracy readings (see inset, next page). The front polycarbonate resin shield is also curved to act as a magnifying glass, which yields superior performance over other rotameters with standard designs.
