Introduction
This instrument is a two-wire electromagnetic flowmeter which operates on the 4-20
mA DC. It measures the flow rate of the conductive fluid flowing in the detector and
outputs a signal that is suitable for the measuring range.
Concept of flow rate measurement by this instrument
The concept of a flow rate measuring system using this instrument is shown.
Analog output
If the instantaneous flow rate values are to be output as an analog variable to the
control equipment, configure the system to output an analog output.
Digital output (DE output)
Use this system configuration if the instantaneous flow rate values, instrument
database and self-diagnosis results are to be output as digital variables (DE outputs) to
the control equipment.
Pulse output
As a pulse output, the open-collector output is available. Pulse frequencies up to 200
Hz can be output. The pulse output can be output simultaneously with an analog output.
If the integrated flow values are to be output as a pulse to control equipment, wire an
another two-wire to output a pulse output.
Contact output
Instead of the pulse output, a contact output the open-collector output is available. The
contact output can be output simultaneously with an analog output.
