Wireless by Emerson

The Emerson Wireless network is a self-organizing solution. Wireless field instruments send data to a
Gateway, directly or routed through any of the wireless devices in the network, as illustrated in
Figure 2-5. Multiple communication paths are managed and analyzed 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, WiFi, and EMC sources is avoided through Time 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.

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.
