Configure Density Measurement - Emerson Micro Motion 4200 Configuration And Use Manual

Configure process measurement
April 2019
Cutoff interaction with mA Output Cutoff higher than Gas Standard Volume Flow Cutoff
Configuration:
mA Output Process Variable for the primary mA Output: Gas Standard Volume Flow Rate
•
• Frequency Output Process Variable: Gas Standard Volume Flow Rate
• mA Output Cutoff for the primary mA Output: 15 SLPM (standard liters per minute)
• Gas Standard Volume Flow Cutoff: 10 SLPM
Result:
• If the gas standard volume flow rate drops below 15 SLPM but not below 10 SLPM:
— The primary mA Output will report zero flow.
— The Frequency Output will report the actual flow rate, and the actual flow rate will be used in all
internal processing.
• If the gas standard volume flow rate drops below 10 SLPM, both outputs will report zero flow, and 0 will be
used in all internal processing.

4.5 Configure density measurement

The density measurement parameters control how density is measured and reported. Density measurement
is used with mass flow rate measurement to determine liquid volume flow rate.

Density Measurement Unit controls the measurement units that will be used in density calculations and
reporting.
Restriction
If the API referral application is enabled, you cannot change the density measurement unit here. The density
measurement unit is controlled by the API table selection.
Procedure
Set Density Measurement Unit to the option you want to use.
Default: g/cm³ (grams per cubic centimeter)
Options for Density Measurement Unit
The transmitter provides a standard set of measurement units for Density Measurement Unit. Different
communications tools may use different labels.
