Remote-Mount Meter and Transmitter Installation (Model 3xxCi-R)
The physical properties, acoustic properties, and calibration of the meter body are pre-
programmed into the transmitter; therefore, the meter body and transmitter are manufactured as a
matched set and must be installed as a pair. Failure to install transmitters and meter bodies as
matched sets can result in erroneous flow measurements.
Should a customer receive multiple meter bodies and transmitters in one shipment, the installer
must verify that each transmitter is installed with the meter body for which it was programmed.
If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely affected,
thus ensuring that the hazardous location protection is not compromised.
Note – All wiring between the transmitter and the meter body must be routed through grounded metal
conduit or equivalent. All wiring to the transmitter is to be routed in shielded conduit that meets site
environment specifications.
This section describes the installation procedure for installing the transmitter separately from the meter
body. Refer to Figure 3.1 for the remote mounted transmitter configuration. The transmitter may be
mounted according to this section within 100 meters (~300 feet) of the meter body. For distances further
than 100 meters, contact Cameron.
Note – Conductor insulation for cabling must be rated for a voltage of 300V and a minimum temperature as
follows:
• For units rated with Ta max = 70°C: “Use conductors for 85°C”
• For units rated with Ta max = 110°C: “Use conductors for 125°C”
• For units rated with Ta max = 125°C: “Use conductors for 140°C”
• For units rated with Ta max = 140°C: “Use conductors for 155°C”
