Yokogawa 415 Steam and Gas - Manual (Page 62)

Sat Steam Input With saturated steam it is only necessary to use
either a pressure or temperature sensor, but not
both. The user can program which sensor is to
be used in the system.
FLOW PARAMETERS
K-factor The pulses/m

or pulses/ft
3
produced by a
frequency type flowmeter.
Flow Signal Type
(Analog Input) Differential refers to all devices where the
signal is pressure related, such as orifice, pitot
tubes, wedges or target flowmeters.
Volumetric refers to flowmeters producing a
truly volumetric signal such as vortex, turbine
or positive displacement meters.
Flow Correction Square root applies to most standard
differential pressure devices where there is a
square law relationship between flow and the
output signal.
Linear applies to D. P. transmitters with square
root extractors or to meters which produce a
linear flow signal, such as laminar flow tubes
or Gilflo meters.
Non-Linear applies if a custom non-linearity
correction curve is to be programmed.
Flow Cutoff The flowrate, as a percentage of the SPAN
below which the flow is not displayed or
integrated.
