WARNING!
The power supply interfaces of the FLC-UFL
series flowmeter are reverse polarity protected
up to 250 mA max. Always connect via a suited
intrinsically safe isolator or barrier.
Refer to Control drawing 81500909 for detailed
information.
4.3.3 Main board - Frequency out
A frequency out / pulse output is available on the mainboard
(base configuration). The main purpose of this output is
to provide pulses proportional to the volume flowing through
the pipeline. The number of pulses per unit volume (m
3
or
cubic feet) is printed on the nameplate.
