Cole-Parmer 65 mm Correlated PTFE Flowmeter, Valved, Sapphire, 032-15

The substitution of metal fittings with PTFE eliminates a potential contamination source for high-purity applications. The glass tube utilizes a fused ceramic scale for a precise, permanent measuring guide. In addition, a vertical-tangential locator line provides readings with hairline accuracy. Further improving readability is a front shield that magnifies the scale 16%. An anodized aluminum frame protects the heavy-walled glass flow tube; a white acrylic back plate protects and enhances viewing in the protective frame. Select a flowmeter with a valve for flow rate control. The standard valve is suitable where high resolution metering is not essential. The high precision valve features a fine-adjust 16-turn “non-rising stem” to more accurately set your desired flow rate. All flowmeters come with correlation data sheets for water and numerous gases (listed below) at standard temperature and pressure (STP). Designed for high-purity applications with flexibility for a broad array of gases Compact design is ideal for small panels or cramped workspaces High turndown—minimum flow rate is less than one-tenth of maximum flow High-precision valve option allows monitoring and control.
