SPEED
Numeric entry; Units ft/s or m/s based on velocity units
SPEED UNITS Ft/s or m/s
SPECIFIC
GRAVITY
Numeric entry; Specific gravity (density relative to water), pipe size
and viscosity are used to calculate the Reynolds number The Reynolds
number indicates whether the fluid is in turbulent, transition or laminar
flow and the flow profile
VISCOSITY
Numeric entry; Units centipoise (cP) or mPa-s Dynamic viscosity of
the fluid
VISCOSITY
UNITS
Units centipoise (cP) or mPa-s
REFERENCE
TEMP
Numeric entry, F or C Default 15 °C Reference temperature of viscosity
and specific gravity
REF TEMP
UNITS
F or C
SPECIFIC
HEAT
Numeric entry; Units: joule/gram °C; min 0 01, max 65 0; Specific heat
capacity is the heat capacity per unit mass of a material

SPACING
*Numeric display 0 to 300 units in" or millimeters, based PIPE settings
The spacing required between two transducers based on the pipe parameters Take
this measurement between the lines scribed into the side of the transducers or use
the scale on the rails, if used See the transducer user manual For Cx transducers
with fixed spacing, the parameter will not be shown
