5.2Operation
The Rosemount™ 708 Acoustic Wireless Transmitter measures ultrasonic acoustic energy and waveguide
temperature. The acoustic level is reported in 'counts,' which are a relative indication of the magnitude.
The sensor used in the Rosemount 708 Transmitter is sensitive to a broad range of frequencies to work in
many different applications. The acoustic measurement or “count” in the transmitter is an average of the
broad range of frequencies. No additional signal processing is performed to isolate specific frequencies.
This count information is used to determine the state of a steam trap, pressure relief valve, or other
mechanical system. The device works similarly to a discrete device, looking for a large change in noise
level occurs during a leak or release. In the case of steam traps, SteamLogic

Recommended Practices
May 2017
00809-0100-4708, Rev DA
Appendix CRecommended Practices
Follow all recommended practices to ensure highest data reliability. Deviation from these best practices
may require device repeaters in the network to maintain 99 percent data reliability. Follow these
guidelines to achieve the best possible Smart Wireless Network:
1. Scope each wireless network field to a single process unit.
2. Minimize the number of hops to the Gateway to reduce latency. Contain a minimum of five wireless
instruments within effective range of the Smart Wireless Gateway.
3. Have at least three devices with potential communication paths. For stronger performance, increase
the required number of wireless neighbor devices to four or five. This increases the number of
potential paths and optimizes network performance.
4. Have 25 percent of wireless instruments in the network within range of Smart Wireless Gateway.
Other enhancing modifications include creating a higher percentage of devices within effective range
of the Gateway to 35 percent or more. This clusters more devices around the Gateway and ensures
fewer hops and more bandwidth available to WirelessHART
®
devices with fast scan rates.
Reference Manual
5. Minimize the path distance from the Gateway. For better performance, the path is typically within
range of one or two hops. This will utilize path redundancy and create very short transit times.
6. Determine effective range by type of process unit and density of the infrastructure surrounding the
network.
C.1Effective range
Heavy Obstruction: 100 ft. (30 m)–Typical heavy density plant environment; a truck or equipment
cannot be driven through this.
Medium Obstruction: 250 ft. (76 m)–Typical light process areas; lots of space between equipment and
infrastructure.
Light Obstruction: 500 ft. (152 m)–Typical of tank farms; despite tanks being big obstructions
themselves, lots of space between and above makes for good RF propagation.
Line of Sight: 750 ft. (230 m)–No obstructions between WirelessHART
minimum of 6 ft. (2 m) above ground or obstructions.
For examples and complete explanations, refer to the IEC62591 WirelessHART System Engineering
