Emerson Wireless

Emerson Wireless is a self-organizing network solution. Wireless field instruments send
data to a Gateway, directly or routed through any of the wireless devices in the network, as
illustrated in
parallel to assure optimal communication and sustained network reliability even if
obstructions are introduced.

Gateways interface with existing host systems using industry standard protocols, and
native integration into DeltaV
Interference from other radios, Wi-Fi
Synchronized Channel Hopping and Direct Sequence Spread Spectrum (DSSS). Also, a
layered security implementing industry standard Encryption, Authentication, Verification,
Anti-Jamming, and Key Management ensures that data transmissions are secure and
received only by the Gateway.
The Rosemount 3308 Series is a member of the Emerson Wireless portfolio, whose
wireless network experience totals billions of operating hours, hundreds of thousands of
field devices, and tens of thousands of networks around the world.

Application characteristics

2.4.1 Tank shape
The guided wave radar transmitter is insensitive to the tank shape. Since the radar signal
travels along a probe, the shape of the tank bottom has no effect on the measurement
performance. The transmitter handles flat or dish-bottom tanks equally well.
2.4.2 In-tank obstructions
The Rosemount 3308 Series Transmitter is relatively insensitive to objects in the tank since
the radar signal is transmitted along a probe.
