4.6 Configure referred viscosity measurement
Referred viscosity is line viscosity corrected to a reference temperature. In other words, this
is the viscosity that the device would report if the line temperature matched the reference
temperature.
Three methods are available to calculate referred viscosity. These methods are described
in the following table.
Configuration methods for referred viscosityTable 4-4:
Referred viscosity calculation
method Description
ASTM D341 Single-Curve • Based on ASTM D341 standards
• Applicable only to petroleum products
• Used when the meter will measure only one process fluid
ASTM D341 Multi-Curve • Based on ASTM D341 standards
• Applicable only to petroleum products
• Supports measurement of two to eight process fluids from
one configuration
