2.1.2 Model with remount mount design
The transmitter is mounted in a separate location from the flowmeter sensor. The electrical
connection between the transmitter and the sensor is provided by a signal cable.
Without a pre-amplifier, the maximum permissible signal cable length is 50 m (164 ft) with a
minimum conductivity of 5 µS/cm.
With a pre-amplifier, the maximum permissible signal cable length is 200 m (656 ft).
Two terminal box variants are available for the ProcessMaster flowmeter sensor:
• Aluminum terminal box
• Plastic terminal box
The external transmitter is available in two housing designs:
Single-compartment housing:
With the single-compartment housing, the electronics area and the connection area are not
separated from each other.
