Cole-Parmer PMR1-010831 浮子流量計

Cole-Parmer PMR1-010831 浮子流量計

前方面板的放大系數(shù)為16％，易于清晰的讀取數(shù)據(jù)

這些直讀流量計的流體管上附有帶毫米刻度的陶瓷片。閱讀浮子位置的垂直切線定位線去確保報了流量計的準確性。正面的聚碳酸酯面板放大系數(shù)為16％，可以方便，準確的讀數(shù)。 

根據(jù)您的具體需要和所測量流體選擇一款最適合的流量計。非浸濕部件包括鋁框側(cè)板，聚碳酸酯防護罩，壓克力背板 

單位刻度分別刻在黑色玻璃（G），316不銹鋼（SS），藍寶石（SA），和鎢鈷硬質(zhì)合金上（見表格）。該直讀流量計適用于氬氣，二氧化碳，氦，氮，氧，可撥打我們的售后電話，獲取更多信息。 

入口和出口設(shè)置1/8“NPT（F）帶外螺紋的螺絲用于面板安裝（附帶兩個鋁制固定螺母）。對于非腐蝕氣體或液體，鋁制部件是性價比較高的選擇，鋁制配件主要有丁腈橡膠O型圈，高硼硅玻璃流量傳感器，316不銹鋼（SS）150目進口屏幕，玻璃或316 SS浮子等。 當被測流體為水時，黃銅是不錯的選擇。黃銅配件主要有316不銹鋼鍍鉻黃銅配件，丁腈橡膠O型圈，高硼硅玻璃流量傳感器，316不銹鋼150目入口濾網(wǎng)，玻璃或316 SS浮子。 316不銹鋼能承受較高的溫度和壓力;具有極好的化學兼容性。316不銹鋼的配件主要有為316 SS的Viton? O型圈，高硼硅玻璃流量傳感器，316不銹鋼150目進口屏幕和玻璃或316 SS浮子。 閥門選項包括無閥和有閥兩種，閥門安裝在流量計入口底部，但可重新配置在出口處。對于正壓力的氣體或液體閥門一般配置在入口;在真空環(huán)境下，閥門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.
