The preceding terms are related by the following formulae:
To create a special unit, you must:
1. Identify the simplest base volume or mass and base time units for your special mass flow or
volume flow unit. For example, to create the special volume flow unit pints per minute, the
simplest base units are gallons per minute:
•
Base volume unit: gallon
•
Base time unit: minute
2. Calculate the conversion factor using the formula below:
Note: 1 gallon per minute = 8 pints per minute
3. Name the new special mass flow or volume flow measurement unit and its corresponding
totalizer measurement unit:
•
Special volume flow measurement unit name: Pint/min
•
Volume totalizer measurement unit name: Pints
Note: Special measurement unit names can be up to 8 characters long (i.e., 8 numbers or letters), but
only the first 5 characters appear on the display.
4. To apply the special measurement unit to mass flow or volume flow measurement, select
Special
8.3.2
Special measurement unit for mass flow
To create a special measurement unit for mass flow;
•
Using ProLink II, see Figure C-3.
•
Using the Communicator, see Figure C-7.
Note: You cannot create a special measurement unit for mass flow with the display, but you can view
the special measurement unit for mass flow on the display.
The following general steps are required:
1. Specify the base mass unit.
2. Specify the base time unit.
3. Specify the mass flow conversion factor.
4. Assign a name to the new special measurement unit for mass flow.
5. Assign a name to the unit to be used for the associated mass flow totalizer and inventory.
