Mass/volume and time conversion example
To find the Base per Custom relationship for a custom unit of standard millions of standard cubic feet per
day (mmcfd) and a base unit of standard cubic feet per minute (StdCuft/min), input the following:
Custom Unit = mmcfd
Base Unit = StdCuft/min
Because:
1 mmcf (Millions of Standard Cubic Feet) = 1000000 StdCuft (Standard Cubic Feet) and
1 d (Day) = 1440 min (Minutes)
Then:
1 mmcfd =
⫻
⫻
= 694.444 StdCuft/min
1 mmcfd = 694.444 StdCuft/min
Therefore:
Base per Custom =
=
= 694.444
Figure 2-30. Flow Rate Custom Units - Mass/Volume and Time Conversion Example
Under the
Custom Units Setup
heading, the user may configure a custom unit for the flow rate
measurement. Custom units allow the flow rate to be displayed in units of measure that are not standard
in the Rosemount 3051SMV.
