World’s first true wireless guided wave radar level transmitter?

02 July 2013

Emerson Process Management has introduced what it believes is industry’s first true wireless Guided Wave Radar (GWR) transmitter for continuous level and interface monitoring.

The new IEC 62591 (WirelessHART) Rosemount 3308 wireless GWR transmitter has been introduced to meet the need for accurate level monitoring in remote or difficult to reach locations where installing new cabling would be costly or impractical.

GWR transmitters are used for a wide range of measurement and control applications, including process level measurement in vessels and storage tanks in refineries, oil fields, offshore platforms, chemical and industrial plants. In well production applications, for example, they are used to measure the level in tanks used for the storage of production, and the delivery water and injection chemicals.

Emerson’s Smart Wireless technology is said to reduce installation and configuration time. Because there is no need for cabling, trenching, conduit runs and cable trays, costs are typically reduced by 30% or more compared with a wired solution. Once a wireless network has been established, any WirelessHART enabled device can join the network and take advantage of the benefits of an existing Smart Wireless infrastructure.

The Rosemount 3308 Wireless GWR transmitter features enhanced configuration and diagnostics. It provides an easy and cost effective way to add visibility across a wide range of industries and applications, ensuring plant and operator safety and improving process efficiency.

Based on GWR technology, the Rosemount 3308 is a top-mounted device for direct level and interface measurement of liquids. It is virtually unaffected by changing process conditions such as density, conductivity, temperature and pressure, and because it does not have moving parts, no calibration is required and maintenance is minimised.
