Azbil Corporation Model MTG11A/18A/11B/18B/14C System configuration and structure
Model MTG11A/18A, MTG11B/18B, MTG14C 1-5
System configuration for analog output and pulse output
System configuration
An example of the system configuration is shown.
The flow rate is available as an analog 4-20 mA DC output and totalized value is
available as a pulse 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 inputs the pulse output, and displays the
totalized value.
~Note Open collector: It is pulse output method to use the transistor contact.
