Reference K-Factor; Flange Type - Emerson Rosemount 8600 Series Reference Manual

Fixed process density
FastKeys
Process Density is required only if you have designated mass units for your flow rate units.
You will first be prompted for density units. It is required for the conversion from volumetric
units to mass units. For example, if you have set flow units to kg/sec rather than gal/sec, a
density is required to convert the measured volumetric flow into the desired mass flow. The
Fixed Process Density must be entered even in temperature compensated Saturated Steam
applications as this value is used to determine flow sensor limits in Mass Flow Units.
Note
If mass units are chosen, you must enter the density of your process fluid into the software.
Be careful to enter the correct density. The mass flow rate is calculated using this
user-entered density, and any error in this number will cause error in the mass flow
measurement. If fluid density is changing over time, it is recommended that volumetric
flow units be used.
2.3.3

Reference K-factor

FastKeys
The reference K-factor is a factory calibration number relating the flow through the meter
to the shedding frequency measured by the electronics. Every Rosemount 8600 meter
manufactured by Emerson is run through a water calibration to determine this value.
2.3.4

Flange type

FastKeys
Flange Type enables you to specify the type of flange on the flowmeter for later reference.
This variable is preset at the factory but can be changed if necessary.
