Delta Determines the difference between two measurement values and divides the result
by the time difference between the time stamps of the measurement values. The
time unit (value/sec., value/min., ...) for the result can be selected via the "Time
basis" parameter located in the "Calculation" tab. It is thus possible to convert the
meter reading (m
3
) of the source in to a flow rate (m
3
/min.) (see "Additional
explanation: Delta mode" on page 69).
