ProcessMaster is available in two product series:
•  FEM610 with base functionality
•  FEM630 with extended functions and options
Integral mount design
For devices with an integral mount design, the transmitter 
and flowmeter sensor form a single mechanical unit.
Remote mount design
For devices with a remote mount design, the transmitter and 
flowmeter sensor are mounted in separate locations.
The electrical connection between the transmitter and the 
flowmeter sensor is provided by a signal cable.
A maximum signal cable length of 164 ft (50m) is possible.
Notes on the transmitter housing
The transmitter is available in two housing designs:
•  Single-compartment housing: 
In the single-compartment housing, the electronics 
chamber and the connection chamber in the transmitter 
are not separated from each other.
•  Dual-compartment housing: 
In the dual-compartment housing, the electronics 
chamber and the connection chamber in the transmitter 
are separated from each other.
