Power Supply
HART Analog
External power supply required. Flowmeter operates on 10.8 to 42 Vdc terminal voltage (with
250-ohm minimum load required for HART communications, 16.8 Vdc power supply is
required)
F
OUNDATION fieldbus
External power supply required. Flowmeter operates on 9 to 32 Vdc, 18 mA maximum.
Power Consumption
One watt maximum
Load Limitations (HART Analog)
Maximum loop resistance is determined by the voltage level of the external power supply, as
described by:
NOTE
HART Communication requires a minimum loop resistance of 250 ohms.
