Thermal flow meter / mass / for gas / in-line

The AALBORG DFM - digital mass flow meter is a programmable thermal mass flow meter with digital signal processing. It uses a RS485 / RS232 digital interface and provides 0 to 5Vdc or 0 to 10Vdc or 4 to 20 mA outputs for flow, pressure and temperature. It provides access to applicable internal data including: flow, temperature, pressure reading, auto zero, totalizer and alarms settings, gas table, conversion factors and engineering units selection, dynamic response compensation and linearization table adjustment.

The module supports 10 different engineering units including user defined and stores calibration data for up to 10 different gases. It accommodates a programmable 12 digits totalizer which indicates total gas volume, flow alarm / pressure alarm / temperature alarm limits for high and low gas flow with relay output, internal conversion factors for up to 32 gases, 4 button keypad which includes graphical LCD with back light, digital / analog outputs which can operate parallel, self diagnostic tests and automatic zero adjustments.
