System configuration for analog output
System configuration
An example of system configuration is shown. The instantaneous flow rate values
measured by this instrument are output as a 4-20 mA DC analog signal.
In this system configuration, the analog signal from the instrument can be output
directly to a host control system.
• Two wired magnetic flowmeter: Measures flow rate and outputs instantaneous
flow rate value as an analog signal.
• Communicator: Used to communicate with this instrument, read data and change
the instrument data settings.
