The Calibration Menu contains the calibration coefficients for the flow meter. These
values should by changed only by properly trained personnel. The Vortex Coef Ck and
Low Flow Cutoff are set at the factory. Consult the factory for help with these settings if
the meter is showing erratic flow rate. The units of measurement used in the Calibration
Menu are preset and are as follows: Density = lbm/ft
3
, Reference Density = lbm/ft
3
,
Viscosity = centipoise.
