When applying the 45S into a single phase, three wire, 120/240 volt service this meter is being correctly applied as a Blondel’s solution. Many power companies trick Blondel’s Theorem by installing a Form 4S meter (a single element meter) for the single phase three wire, 120/240 volt service and for the 4S in this installation and it is seen as acceptable metering (by industry standards).

Form 16s meters are self-contained meters that are most commonly used to meter 4 wire wye services. Here is the wiring diagram for the form 16s meter. These are the most common meter forms that are used. Also, I would like to add that with the invention of the solid state meter came a feature known as auto-ranging.
