Input Power Requirements
F-3000 Electromagnetic Flow Meters equipped with standard transmitters
are available with two different options for input power. This is not a user

to earth through an earth wire. This connection is required to prevent
random electrical noise from interfering with the operation of the meter.
Low Voltage: 10 – 63 VDC, 15 – 45 VAC 45/66 Hz, 300 mA maximum
High Voltage (Mains): 90 – 265 VAC 45/66 Hz, 35 mA maximum
