Declaration of SEP
Fisher Controls International LLC declares this
product to be in compliance with Article 4 paragraph
3 of the Pressure Equipment Directive (PED)
2014/68/EU. It was designed and manufactured in
accordance with Sound Engineering Practice (SEP)
and cannot bear the CE marking related to PED
compliance.
However, the product
may
bear the CE marking to
indicate compliance with
other
applicable European
Community Directives.
NOTE: Specialized instrument terms are defined in ANSI/ISA Standard 51.1 -
Process Instrument Terminology.
1. The pressure/temperature limits in this document and any applicable standard or code limitation should not be exceeded.
2. Normal m
3
/hr—Normal cubic meters per hour (0
_
C and 1.01325 bar absolute). Scfh—Standard cubic feet per hour (60
_
F and 14.7 psia).
3. Performance values are obtained using a 546 transducer with a 4 to 20 mA DC input signal and a 0.2 to 1 bar (3 to 15 psig) or a 0.4 to 2 bar (6 to 30 psig) output signal. Ambient temperature
is 24
_
C (73
_
F). A transducer with other input or output signals might exceed these values. Reference accuracies of
±
3.5% can be expected with output ranges starting near zero psig.
4. Reference accuracy includes the effects of non-linearity, hysteresis, and deadband per SAMA Standard PMC 20.1-1973.
