Aalborg Instruments Three Channel Flow Tube Meter P31S3B*2

The Three Channel Flow Tube Meter, part number P31S3B*2, from Aalborg Instruments is designed for precise measurement of low flow rates in various applications, including gas metering in chromatography and laboratory settings. This model features rib-guided or fluted metering tubes that enhance stability and accuracy of readings. It allows for the interchangeability of flow tubes and floats, facilitating easy installation and maintenance. The meter is equipped with built-in needle valves or high precision metering valves, depending on the configuration, which can be positioned at either the inlet or outlet based on the application requirements. The maximum operating pressure is 200 psig (13.8 bars) and the maximum operating temperature is 250 ¬8F (121 ¬8C). The flow tubes are constructed from heavy-walled borosilicate glass, ensuring durability and chemical compatibility. With a standard accuracy of ¬±2% full scale and an optional calibrated accuracy of ¬±1% full scale, this flow meter is suitable for applications requiring reliable flow measurement. The device is shipped fully assembled and includes standard mounting fittings, a protective front shield with a magnifier lens for improved reading resolution, and options for panel or bench mounting.
