sensor (CMF series) is one part of a
Coriolis flowmetering system. The other part is a transmitter.
Transmitter connections
The sensor (except CMF300A) is available with two different transmitter
connections:
•
An integral core processor for connecting to a 4-wire remotely mounted
transmitter or to a user-supplied remote host.
•
A 9-wire junction box for connecting to a remotely mounted transmitter,
or to a remotely mounted core processor.
The CMF300A sensor is available only with a remote junction box.
European installations
This Micro Motion product complies with all applicable European
directives when properly installed in accordance with the instructions in
this manual. Refer to the EC declaration of conformity for directives that
