Considerations

3.3.1

General

Measurement performance depends upon proper installation of the transmitter and impulse
piping. Mount the transmitter close to the process and use a minimum of piping to achieve best
performance. Also, consider the need for easy access, personnel safety, practical field
calibration, and a suitable transmitter environment. Install the transmitter to minimize
vibration, shock, and temperature fluctuation.
3.3.2

Wireless

Power Up Sequence
The Power Module should not be installed on any wireless device until the Smart Wireless
Gateway is installed and functioning properly. Wireless devices should also be powered up in
order of proximity from the Smart Wireless Gateway beginning with the closest. This will result
in a simpler and faster network installation. Enable High Speed Operation on the Gateway to
ensure that new devices join the network faster. For more information see the Smart Wireless
Gateway Manual (Doc. No. 00809-0200-4420).
Field Communicator Connections
In order for the Field Communicator to interface with the 3051, the Power Module must be
connected.

Note
For steam service or for applications with process temperatures greater than the limits of the
transmitter, do not blow down impulse piping through the transmitter. Flush lines with the
blocking valves closed and refill lines with water before resuming measurement.
Note
When the transmitter is mounted on its side, position the Coplanar flange to ensure proper
venting or draining. Mount the flange as shown in
connections on the bottom for gas service and on the top for liquid service.
