System configuration for analog output and contact output
System configuration
In the system configuration shown below, the instantaneous flow rate is output as 4-20
mA analog signal and alarm is output when the status output is configured for the
alarm function. As an alarm, self diagnosis output (critical failure) or upper/lower
limit alarm is output.
• Two wired magnetic flowmeter: Measures flow rate and outputs the instantaneous
flow rate value as an analog signal.
• Communicator: Used to communicate with this instrument, read data and change
the instrument data settings.
• Pulse output receiver equipment: It receiver the pulse output, and displays the
totalized value.
~Note
Open collector: pulse output method using the transistor contact.
