Aalborg Instruments XFMS-010081 Digital Mass Flow Meter

Aalborg XFMS-010081 Digital Mass Flow Meter is a compact, stand-alone device that measures mass flow of air from 0 to 100 mL per minute with digital accuracy. It communicates over RS-485 for reliable, multi‑instrument networking and can output an analog signal (0–5 V) on compatible configurations, making it suitable for integration with data loggers and control systems. The unit draws a maximum of 150 mA and is designed to live on an RS-485 bus with other Aalborg XFM meters, enabling scalable monitoring across a system. As part of the XFM digital mass flow meter family, the XFMS-010081 can store calibration data for up to 10 different gases and supports gas‑table‑based conversion factors and engineering units, facilitating switching between gases like air and nitrogen without recalibration. Features such as a programmable flow totalizer, high/low flow alarms, automatic zero adjustment, and status diagnostics via an LED are typical of Aalborg's XFM line, providing actionable flow information and alerting when limits are reached. These meters use a precision microcontroller and non-volatile memory to maintain calibration and settings across power cycles, making them suitable for process automation, analytical instrumentation, and lab‑scale gas delivery where precise, repeatable flow control is required.
