The special measurement unit is stored in the transmitter. You can configure the
transmitter to use the special measurement unit at any time.
Example: Defining a special measurement unit for mass flow
You want to measure mass flow in ounces per second (oz/sec).

Overview
Flow Damping controls the amount of damping that will be applied to the measured mass
flow rate. It affects flow rate process variables that are based on the measured mass flow
rate. This includes volume flow rate and gas standard volume flow rate.
Flow Damping also affects specialized flow rate variables such as temperature-corrected
volume flow rate (API referral) and net mass flow rate (concentration measurement). It is
not applied to the flow rate received via the frequency input.
Damping is used to smooth out small, rapid fluctuations in process measurement. The
damping value specifies the time period, in seconds, over which the transmitter will spread
changes in the process variable. At the end of the interval, the internal value of the process
variable (the damped value) will reflect 63% of the change in the actual measured value.
Procedure
Set Flow Damping to the value you want to use.
Configuration and Use Manual
Enter Mass Flow Conversion Factor.
The original mass flow rate value is divided by this value.
Set Mass Flow Label to the name you want to use for the mass flow unit.
Set Mass Total Label to the name you want to use for the mass total and mass
inventory unit.
Set Base Mass Unit to Pounds (lb).
Set Base Time Unit to Seconds (sec).
Calculate Mass Flow Conversion Factor:
a. 1 lb/sec = 16 oz/sec
b. Mass Flow Conversion Factor = 1 ÷ 16 = 0.0625
Set Mass Flow Conversion Factor to 0.0625.
Set Mass Flow Label to oz/sec.
Set Mass Total Label to oz.
