The flow rate can be displayed in volumetric flow or
mass flow engineering units for standard or actual
(temperature, pressure) conditions. Flow meters can
be programmed locally by the four button keypad and
LCD or remotely via RS-232/RS-485 interface.
DFM flow meters support various functions including:
flow totalizer, flow, temperature, pressure alarms,
automatic zero adjustment, 2 relay outputs, 0-5 Vdc /
0-10 Vdc / 4-20 mA analog outputs for flow, pressure
and temperature.
DFM's are offered either as Digital Mass Flow Meters,
Model Numbers: DFM26, 36, & 46 or as a Digital
Multi-Parameter Meters, Model Numbers, DFM27, 37
& 47. Model Numbers are displayed in Table 24.
