Procedure
1. Specify Base Mass Unit.
Base Mass Unit is the existing mass unit that the special unit will be based on.
2. Specify Base Time Unit.
Base Time Unit is the existing time unit that the special unit will be based on.
3. Calculate Mass Flow Conversion Factor as follows:
a) x base units = y special units
b) Mass Flow Conversion Factor = x ÷ y
4. Enter Mass Flow Conversion Factor.
The original mass flow rate value is divided by this value.
5. Set Mass Flow Label to the name you want to use for the mass flow unit. Maximum of 8 characters.
6. Set Mass Total Label to the name you want to use for the mass total and mass inventory unit. Maximum
of 8 characters.
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
To measure mass flow in ounces per second (oz/sec):
1. Set Base Mass Unit to Pounds (lb).
2. Set Base Time Unit to Seconds (sec).
3. Calculate Mass Flow Conversion Factor:
a. 1 lb/sec = 16 oz/sec
b. Mass Flow Conversion Factor = 1 ÷ 16 = 0.0625
