Emerson’s Smart Wireless Solution Monitors
Remote Reaction Tank at Nu-West Industries
BENEFITS
•Smart Wireless network provides accurate minute-by-minute
readings from 16 measurement points on a reaction tank
located about 250 feet from the central control room
•A wired solution would have been very challenging due
to the remote location
•Smart Wireless provided a low-risk and simple solution
•The self-organizing architecture does not require
line-of-sight
CHALLENGE
Nu-West Industries phosphate-based fertilizer plant in Soda Springs,
Idaho wanted a reliable way to monitor pressures and temperatures at
a remote location. The self-organizing Smart Wireless system provides
accurate minute-by-minute readings from 16 measurement points on
a reaction tank located about 250 feet from the central control room.
The remote tank is 40 feet high and has four different beds of gases
used to react with certain process chemicals. Even though this is not
classified as a hazardous area, the tank layout and distance involved
made running wires to the tank and mounting instruments both difficult
and expensive.
SOLUTION
Emerson’s Smart Wireless technology was selected by Nu-West, a
subsidiary of Agrium US, because it proved to be the easiest to install,
most secure, and most reliable solution to the problem of retrieving
essential operating information at an extended distance. Transmissions
from the remote tank at Nu-West are received by a Smart Wireless
Gateway and channeled via the PlantWeb® control architecture to the
DeltaV™ automation system where the AMS® Suite: Intelligent Device
Manager software recognizes readings that are out of the norm,
enabling operators to take action to control the reactions in the tank.

“Hard wiring this installation
would have been very challenging
due to the location of the vessel.
Given the low-risk and simplicity of
the application, this seemed an
ideal place to try Emerson’s wireless
package. The self-organizing
architecture was the clincher since
less than perfect line-of-sight to
each device is not a concern with
this system. We already have
plans to add more devices to the
network.”

SMART WIRELESS APPLICATIONS
RESULTS
The self-organizing Smart Wireless system provides accurate minuteby-minute readings from 16 measurement points on a reaction tank
located about 250 feet from the central control room.
Each wireless device in a self-organizing network can act as a router for
other nearby devices, passing messages along until they reach their
destination. If there is an obstruction, transmissions are simply re-routed
along the mesh network until a clear path to the Smart Wireless Gateway
is found. As conditions change or new obstacles are encountered in a
plant, such as temporary scaffolding, new equipment, or a parked
construction trailer, these wireless networks simply reorganize and
find a way.
All of this happens automatically, without any involvement by the user,
providing redundant communication paths and better reliability than
direct, line-of-sight communications between individual devices and
their gateway. This self-organizing technology optimizes data reliability
while minimizing power consumption. It also reduces the effort and
infrastructure necessary to set up a successful wireless network.
