暗桿針閥

尺寸為150 mm的流量計(jì)也可配備用于特殊應(yīng)用的非升桿式針閥。這種15圈的計(jì)量閥具有優(yōu)越的流量控制，特別適用于色譜分析應(yīng)用。滑動(dòng)錐形針機(jī)構(gòu)實(shí)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(huì)改變或鋸齒狀的流速。

加壓系統(tǒng)屏蔽

這些轉(zhuǎn)子流量計(jì)，帶有精密鉆孔的硼硅酸鹽玻璃計(jì)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(shí)別浮動(dòng)位置。

面板安裝設(shè)計(jì)

這些轉(zhuǎn)子流量計(jì)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(gè)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(gè)孔的直徑應(yīng)為16 mm（5/8”）。

±2% FS Accuracy

Non-Rotating Seal Spindle

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.
