Retrofitting
The MAG-SM in a field mount housing or in a 19”-Design can
also be used to operate the electromagnetic flowmeter
primaries Model 10D1422. Only flowmeter sizes 1/10” to 40”
[DN 3 to DN 1000] can be retrofitted. The following
Interconnection Diagrams can be used for the converter
in a field mount housing or in a 19”-Design.
