Product Data Sheet
DESCRIPTION
The Preso segmented wedge Model COIN® segmented or
segmental wedge design is a differential pressure type
flow element.
CONFIGURATION
The inlet section is the same diameter as the incoming pipe section
and is followed by a precise segmented single piece construction
angled section equal on both sides for bidirectional flow
measurement. The H/ID ratio is determined by the manufacturer
according to recognized standards and formulas. The discharge
coefficient (Cd) is linear and stable in the operating flow range.
MATERIALS
The construction material, instrument connections, instrument
valves or instrument flange connections, and end connections are
selected to meet intended service conditions. Identification tag is
provided as required.
ACCURACY & REPEATABILITY
The accuracy of the COIN meter is within ±3.0% (uncalibrated) and
±0.5% (calibrated) with a repeatability of ±0.2% and turndown
of 10:1 in the corresponding and appropriate range of Reynolds’
Numbers. For custody transfer applications, the COIN meter is
flow tested by an independent NIST certified laboratory under the
design operating conditions and piping configurations.
QUALITY
All COIN meters are manufactured under an ISO 9001:2008 certified
quality program. Certification documentation is available for
inspection. The manufacturer will provide a Flow Calculation Data
Sheet with standard data and formulas for approval by the
design engineer.
APPLICABLE FLUIDS
