The IFC 090/…-EEx signal converter (described in Sect. 1.4-1.5) is mounted on top of the
primary head by four recessed head screws of size M6 with internal hexagonal socket set.

Note
The intrinsically safe electrode circuits of the IFM 6080K/…-EEx compact flowmeter are only
internal circuits and not accessible for the customer.

The two field coils inside the primary head are connected in series and provided with the

type of protection increased safety "e" and encapsulation "m" (DN2.5-15). Meter size

DN25-80 has a flameproof primary housing.
