Cole-Parmer PMR1-010831 浮子流量计

前方面板的放大系数为16％，易于清晰的读取数据

这些直读流量计的流体管上附有带毫米刻度的陶瓷片。阅读浮子位置的垂直切线定位线去确保报了流量计的准确性。正面的聚碳酸酯面板放大系数为16％，可以方便，准确的读数。 

根据您的具体需要和所测量流体选择一款最适合的流量计。非浸湿部件包括铝框侧板，聚碳酸酯防护罩，压克力背板 

单位刻度分别刻在黑色玻璃（G），316不锈钢（SS），蓝宝石（SA），和钨钴硬质合金上（见表格）。该直读流量计适用于氩气，二氧化碳，氦，氮，氧，可拨打我们的售后电话，获取更多信息。 

入口和出口设置1/8“NPT（F）带外螺纹的螺丝用于面板安装（附带两个铝制固定螺母）。对于非腐蚀气体或液体，铝制部件是性价比较高的选择，铝制配件主要有丁腈橡胶O型圈，高硼硅玻璃流量传感器，316不锈钢（SS）150目进口屏幕，玻璃或316 SS浮子等。 当被测流体为水时，黄铜是不错的选择。黄铜配件主要有316不锈钢镀铬黄铜配件，丁腈橡胶O型圈，高硼硅玻璃流量传感器，316不锈钢150目入口滤网，玻璃或316 SS浮子。 316不锈钢能承受较高的温度和压力;具有极好的化学兼容性。316不锈钢的配件主要有为316 SS的Viton? O型圈，高硼硅玻璃流量传感器，316不锈钢150目进口屏幕和玻璃或316 SS浮子。 阀门选项包括无阀和有阀两种，阀门安装在流量计入口底部，但可重新配置在出口处。对于正压力的气体或液体阀门一般配置在入口;在真空环境下，阀门一般配置在出口位置。

Front shields magnify scale 16%—easy to read from a distance

These direct reading flowmeters have a ceramic millimeter scale is fused onto the flowtube. A vertical tangential locator line ensures hairline accuracy in reading float position. The front polycarbonate shields are magnified 16% for easy, accurate readings. 

Select a flowmeter that best suits your application from the several valve options and wetted materials. Nonwetted parts for all models include aluminum frame side plates, polycarbonate shields, and acrylic back plates. 

Units are supplied with either a black glass (G), a 316 stainless steel (SS), a sapphire (Sa), or a carboloy ?float (see tables). Direct reading flowmeters for argon, CO2, helium, nitrogen, and oxygen are available—call our Applications Specialists for more information. 

Inlet and outlet connections are 1/8" NPT(F) with external threading for panel mounting (two retaining nuts are included). 

Flowmeter Options

Aluminum is economical and good for general use with noncorrosive gases and liquids. Aluminum fittings, Buna N O-rings, borosilicate glass flowtubes, 316 stainless steel (SS) 150-mesh inlet screens, and glass or 316 SS floats. 

Brass is economical and good for use with water. Chrome-plated brass fittings, Buna N O-rings, borosilicate glass flowtubes, 316 SS 150-mesh inlet screens, and glass or 316 SS floats. 

316 Stainless Steel withstands higher temperatures and pressures; and features excellent chemical compatibility. Fittings are 316 SS. Viton? O-rings, borosilicate glass flowtubes, 316 SS 150-mesh inlet screens, and glass or 316 SS floats. 

Valve Options include valveless or with valve. Valves come mounted at the inlet (bottom) of applicable flowmeters but can be reconfigured to mount at the outlet. For positive pressure applications with liquids and gases, position the valve at the inlet; for vacuum applications, position at the outlet.t.
