Aalborg Instruments Single Tube Rotameter P11A3-BA0A-044-40-CA

The Aalborg Instruments Single Tube Rotameter, part number P11A3-BA0A-044-40-CA, is designed for low flow rate applications, making it suitable for metering carrier gases in chromatography, as well as for liquid and gas measurement in laboratories and manufacturing processes. This precision instrument features rib-guided or fluted metering tubes that enhance stability and accuracy in readings. The rotameter is shipped fully assembled and includes standard mounting fittings, a protective magnifying front shield, and a back plate. It offers optional built-in control valves, with configurations available for both gas and liquid applications. The maximum operating pressure is 200 psig (13.8 bars) and the maximum operating temperature is 250 °F (121 °C). Flow tubes are made from heavy-walled borosilicate glass, and various float materials are available, including glass, sapphire, and stainless steel. The device supports a useful flow range of 10:1 minimum with one float, and better than 20:1 with two floats. The standard accuracy is ±2% full scale, with an optional calibrated accuracy of ±1% full scale. This rotameter is designed for easy installation and exchange of flow tubes, and it features a "non-rotating" adapter to prevent glass flow tubes from turning during assembly. The OPTIGRAD,Ñ¢ scales are designed to minimize parallax and eye fatigue, ensuring ease of use in various applications.
