A separate flow meter has a high installation cost. Beyond purchase price of the flow meter, there will be material and labour costs for installation, wiring and calibrating a meter.
This also carries added complexity… whereas the Design Envelope pump doesn’t require any of this extra installation complexity, and has the flow meter built-in.
The labour related to maintaining a flow meter and keep it calibrated is an additional ongoing cost. In the case of the Design Envelope pump, no extra maintenance is required to maintain the accuracy of the flow.
Potetial savings also include lifecycle carbon emissions. Standard metering solutions require more pipe and more valves and more wiring, all of which involve extra carbon footprint. The added annual maintenance also involves travel to site which adds to associated lifecycle carbon. Design Envelope solutions let users avoid all of these added emissions.
