function Figure 1-4 shows a sample system configuration in which the instantaneous
flow rate measured by the unit is output with a 4 - 20 mA DC analog signal.
In order to enable communications, a DC power supply and a resistance of
250
Ω
or more must be installed on the receiving side.

• Smart Electromagnetic Flowmeter (device): Measures flow rate and out-
puts an analog signal instantaneous flow rate.
• Smart Communicator (S-SFC): Communicates with the device to read data
and change the device settings.
