Is PAN-42 a utility/revenue-grade meter?
PAN-42 was tested by a 3rd party lab for 1% accuracy according to ANSI C12.1 class 1. This accuracy is sufficient for many billing-level applications, such as M&V, sub metering, etc.
Despite its tested accuracy, PAN-42 is not officially certified as utility grade. This is due to some utility meter requirements (such as an outdoor enclosure and an LCD screen) which it does not have.
