Signal circuits
The vortex flowmeter signal circuits may only be connected to circuits with the following
maximum values. A U
m
of 253 V is required for the power supply units.

With the compact device, the intrinsically safe flow sensor circuits are designed as internal
circuits.
When it comes to the remote versions, the intrinsically safe flow sensor circuits are led through.
The maximum permissible values of the flow sensor circuits considered safe are listed below:
