Introduction
This instrument is an electromagnetic flowmeter and outputs analog and pulse or
contact output. It measures the flow rate of a conductive fluid flowing in the sensor
and outputs a signal according to the set range.

Analog output
If instantaneous flow rate values are to be output as an analog variable to control
equipment, configure the system to deliver an analog output.
Pulse output
As a pulse output, the open-collector output is available. Pulse frequencies up to 200
Hz can be delivered. The pulse output can be delivered simultaneously with an analog
output.
Contact output
Instead of the pulse output, a contact output is available using the open-collector
output. The contact output can be delivered simultaneously with an analog output.
