Imbalance simulator

Orifice meters on one gas system, every error from a cited public figure or a labelled assumption. An explainer: it states no uncertainty for any real installation. The page that explains it

the system set below

Receipt meters Number Pipe inside diameter Beta ratio Upstream pressure Running at, share of dp span

Delivery meters Number Pipe inside diameter Beta ratio Upstream pressure

Deliveries split the receipts' gas equally; each one's dp is solved from that flow.

Which errors are shared Discharge coefficient

by tap and beta band receipts apart from deliveries

Transmitters (dp, pressure, temperature) Bore and pipe diameters Gas analysis

0 is independent at every meter; 1 is one common error. The discharge coefficient's starts at 0, the first row of the page's table; no open source says which value is right.
