SECTION 5.0: FLOW STRAIGHTENER FOR VORTEX FLOW METERS
DESCRIPTION
The optional ow straightener accessory for
ONICON F-2000 Series Vortex Flow Meters is a
wafer-style ow conditioner that is designed to be
installed between two recessed anges (provided
by installer) that are located a speci ed distance
upstream of the ow meter.
Use of a ow straightener signi cantly reduces the
upstream straight pipe length requirement for
ONICON Vortex Flow Meters.
The size of the straightener should always match
the meter size (as opposed to the original pipe size).
The ow straightener is made of 304/A 351 CF8
stainless steel.
