- drewblackwellSep 12, 2017Posting this here as a result from a question that came in under Supporting Documentation (check that post out as well for some additional info!): Signal Calibration: This pertains to the secondary and tertiary devices that convert the meter reads into flow volumes . Specifically, it measures the alignment of flow range conversion with signal span output (typically 4-20mA DC) and SCADA output. The image below helps illustrate the difference in volumetric meter accuracy testing and signal calibration:
Great question! The Variable Production Cost (VPC) is the cost related to your real losses or physical leaks in your systems. It is comprised of the costs to produce and supply the next unit of water (e.g.,
dollars per million gallons). This cost is determined by calculating the summed
unit costs for ground and surface water treatment and all power used for pumping
from the source to the customer. It may also include other miscellaneous unit costs
(such as residuals disposal costs) that apply to the production of drinking water. It
should also include the unit cost of bulk water purchased (Imported Water volume) if
applicable.
