System configuration for pulse output
System configuration
An example of system configuration is shown. Instantaneous flow rate values measured by this
instrument are outputted as a pulse output with the specified pulse width and pulse weight.
Besides an analog signal, this system configuration allows the instrument to output a pulse
output to an electronic counter, sequencer or other host control system or counter.


Smart two-wire electromagnetic flowmeter (main unit): Measures flow rate and outputs a
pulse output signal to an electronic counter. Displays the measured flow rate as a flow rate
value.

Electronic counter: Receives the pulse input signal as input and displays the integrated
value and control the target equipment by batch control function.
