Calculates the sum of the input values within a defined interval.

Parameter

Description

Input Data*

Defines the time series data fed into the function. This can be a sensor ID or another function.

Period

Number of data intervals considered in function

*Input data is optional in most cases. If Info360 detects that the first input is time series data, it will be applied to the function. Otherwise, the current active sensor's data will be used, which is often the case in Reference Charts.

Example Usage as an Expression:

Sum(Volume(),24): For hourly flowrate data, this outputs the cumulative flow volume over a 24 hour window.

Example Reference Chart:

In the following example chart shows Sum(Volume(),24) to display the total number of gallons the passed through the sensor over the previous 24 hours.

Also, it is shown that Sum(x)/x is the same as MA(x).
