1-Meter Filter, Aggregation, and Conversion (kWh to GJ)
Applicable Systems
Primary: Boilers, Coolers, etc.
Objective/Method/Outcome
Objective: Filter and aggregate meter data from a raw cumulative Trend Log sample and output energy data in converted units.
Method: Data transformation is performed in logic flow with aggregation interval on request. Negative cumulative values are replaced with zero values.
Outcome: Filtered, aggregated, and converted energy data on request. Can be used to display energy data in public dashboards via the Kaizen public API.
Logic
Input TL goes through the Delta block, then a negative number filter to zeroes in order to prevent negative number reading. Data is then aggregated and accumulated on an on-request interval.
The Multiple Expressions block [31] then calculates the conversion from USGal to Liters.
