Energy and time conversion example
To find the Base per Custom relationship for a custom unit of thousands of BTU per day (kBtud) and a
base unit of BTU per hour (Btu/h), input the following:
Custom Unit = kBtud
Base Unit = Btu/h
Because:
1 kBtu (Thousands of BTU)= 1000 Btu and
1 d (Day) = 24 h (Hours)
Then:
1 kBtud = ⫻ ⫻ = 41.6667 Btu/h
1 kBtud = 41.6667 Btu/h
Therefore:
Base per Custom = = = 41.6667

Under the Low Flow Cutoff heading, edit the current Minimum DP Value as needed. The unit for this
value is the user-selected DP unit. If the measured DP value is less than the minimum DP value, the
transmitter will calculate the energy value to be zero.
The Sensor Limits and Minimum Span can be viewed under the Energy Rate Sensor Limits heading.
