The Model XFM from Aalborg, Orangeburg, NY, is a thermal mass flowmeter with ±1% F.S. accuracy at calibration temperature and pressure and an optional Profibus DP interface. The device features local or remote automatic sensor zero offset adjustment, aluminum or SS construction, RS-485 or RS-232 interfaces, programmable totalizer, high/low flow alarms, self-diagnostics, 23 volumetric flow or engineering units, and internal or user-specific K factors. The meters have NIST-traceable calibrations.
