Cole-Parmer PMR1-010743 變截面流量計

前面盾牌規(guī)模擴(kuò)大16％ - 易從遠(yuǎn)處看

這些直讀流量計有陶瓷毫米刻度融合到流管，垂直切線定位線確保在閱讀浮動閥位時的位置精度，前面聚碳酸酯屏蔽層，方便、準(zhǔn)確的將讀數(shù)放大16％

從閥門選項(xiàng)和濕材料選擇一個最適合的應(yīng)用程序流量計，Nonwetted部分適用于所有型號包括鋁框側(cè)板，聚碳酸酯護(hù)罩，以及丙烯酸背板。

單位與使用黑色玻璃（G）提供，316不銹鋼（SS），藍(lán)寶石（SA），或碳?浮動（見表格）。有直讀流量計為氬氣，二氧化碳，氦氣，氮?dú)夂脱鯕猓蓳艽蛭覀兊膽?yīng)用專家了解更多信息。

進(jìn)口和出口連接1/8"NPT（F）與外螺紋面板安裝（兩個固定螺母包括在內(nèi)）。

流量計選項(xiàng)

鋁是經(jīng)濟(jì)的與非腐蝕性氣體和液體一般用途。鋁件，丁腈橡膠O型圈，硼硅玻璃型管，316不銹鋼（SS）150目進(jìn)口屏，玻璃或316不銹鋼浮動。

黃銅是經(jīng)濟(jì)和良好的水使用。銅鍍鉻件，丁腈橡膠O型圈，硼硅玻璃型管，316不銹鋼150目進(jìn)口屏，玻璃或316不銹鋼浮動。

316不銹鋼可以承受更高的溫度和壓力，并具有優(yōu)異的化學(xué)相容性。配件是316不銹鋼，氟橡膠O形環(huán)，硼硅酸鹽玻璃流管，316不銹鋼150目入口篩網(wǎng)和玻璃或316不銹鋼漂浮。

閥門選項(xiàng)包括無閥或閥門。閥門過來安裝在適用的流量計的入口（底部），但是可以重新配置在出口處安裝。為正壓力的應(yīng)用與液體和氣體，定位閥在進(jìn)氣口，對于真空應(yīng)用，位置在出口處。

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.
