AAlborg XFM Digital Mass Gas Flow Meter

Digital Mass Gass Flow Meters

XFM Flow Flow unit can be displayed with 23 different volumetric flow or mass flow engineering units specific to the user. The flowmeter can be programmed via RS-232 / RS-485 or Profibus.

AAlborg XFM includes functions such as a programmable flow collector, 2 relay outputs for low and high flow alarm, automatic zero adjustment, selectable analog outputs with 4-20mA and 0 -5 Vdc jumpers, and the ability to store calibration values for 10 different gases.
