Technical Note00840-2600-4811, Rev CAJuly 2012Rosemount 3300 and 5300 document is a guideline for Guided Wave Radar (GWR) applications. Besides providing information on application advantages, product features, different types of applications, and probe styles, it also compares the Rosemount 5300 and 3300 Series GWRs to assist with radar device selection for optimal ADVANTAGES OF GUIDED WAVE RADARAdvantages of Guided Wave Radar compared to other level technologies include: Measures level directly, and is not impacted by density, dielectrics, or conductivity changes Measures through heavy vapors Handles turbulent and low dielectric fluids Can measure through most foams Measures interface applications Measures solids, powders, and granules Measures in small tanks, geometrically difficult tanks, and long nozzles Has no moving parts Displacer and capacitance are easily replacedROSEMOUNT GUIDED WAVE RADAR PRODUCT FEATURESThere are two Guided Wave Radar products offered by Rosemount: the 3300 and the 5300 FeaturesThe Rosemount 3300 Series and Rosemount 5300 Series are multivariable and can measure both level and interface, with a dual compartment head to protect electronics from moisture. The electronics housing can be rotated 360 and in most cases separated from an installed probe without opening the tank. Both provide application flexibility and are available with a full range of probe styles to meet application requirements. The configuration tools have installation wizards with waveform plots to provide easy and powerful configuration and 5300 Series superior performance Handles even the most challenging applications reliably, including process vessels, control and safety, extreme temperature and pressure Microwave innovations as Direct Switch Technology allow use over longer ranges, with lower dielectrics and higher accuracy, even with a single probe Enhanced configuration and diagnostic information through RadarMaster, EDDL-based and DTM-based user interface Probe end projection function provides reliable measurements in applications with low signal strengthRosemount 3300 Series versatile and easy to use Handles most liquid storage and monitoring applicationsExample of a GWR Wave Radar Application GuidelinesTechnical Note00840-2600-4811, Rev CAJuly 2012Rosemount 3300 and 5300 Series2APPLICATIONSIndustrial level measurementsProviding accurate and reliable measurement under process variations and with the ability to handle turbulence, vapors, coating, moisture, dust, foam and geometrically difficult vessels, GWR is a popular alternative for many gases and refrigerantsGuided Wave Radar can handle heavy vapors, and it works well in low dielectric, turbulent applications. This makes it a good choice for liquefied gases including LNG, LPG, anhydrous ammonia, and applicationsThe Rosemount 5303 transmitter measures solids with dielectric constants as low as and a measuring range up to 160 ft. (50 m). Applications include powders and granules, silicon, plastic pellets, cement, fly ash, corn, and many more. It is virtually unaffected by dust, moisture, density changes, and temperature The shape of the material cone is not criticalEasy replacement of mechanical devicesGuided Wave Radar is an ideal, low maintenance replacement for displacers, because it has no moving parts and is unaffected by density changes. The use of a single lead probe further ensures minimal maintenance since it is more tolerant of material coating. Guided Wave Radar is available with flanges that can match the proprietary cage flanges or major displacer manufacturers. A robust high pressure and temperature probe solution for the Rosemount 5300 Series is also available for these thisto minutesTechnical Note00840-2600-4811, Rev CAJuly 20123Rosemount 3300 and 5300 SeriesReplacement of capacitance probesGuided Wave Radar is an excellent replacement for capacitance probes since it requires no calibration and can handle heavy coating. It has a long-lasting microwave electronics that provides extended lifetime compared to capacitance and interface measurementsGuided wave radar measures both the level and interface level in separators, and settling and condensate tanks. The cost for wiring and installation is reduced because there is one tank penetration and a single pair of wires. There are some basic conditions which must be met in interface measurements: The lower dielectric fluid must be on top The two liquids must have a dielectric difference of at least 6 The upper layer dielectric must be known (in-field determination is possible) The 5300 Series HTHP coaxial probes minimum upper layer thickness is 8 in. (20 cm), and with all other probes 5 in. ( cm) The maximum thickness of the upper layer depends on the dielectric, probe type and transmitter Target applications: low upper layer dielectric (< 3), high lower layer dielectric (>20)Demanding environmentsThe Rosemount 5300 Series handles low reflectivity, extreme temperatures and pressures, heavy product coating and saturated steam, making it a reliable alternative for applications such as distillation columns, feed-water tanks, and liquefied thisto minutesTechnical Note00840-2600-4811, Rev CAJuly 2012Rosemount 3300 and 5300 Series4COMPARE AND SELECT ROSEMOUNT GUIDED WAVE RADARSBoth the 3300 and 5300 handles most liquid storage and monitoring applications. However the 5300 with its superior performance handles even the most challenging applications reliably, including process vessels, control and safety. The application conditions described here are where the 5300 is the right Dielectrics with Single ProbeBoth level and interface measurements can be handled with a single lead probe in sticky fluids ( crude oil, waxy oil), which would leave deposits on twin lead spacers. Probe End Projection provides a backup function for challenging applications such as plastic pellets and boiling Measurement RangeHigh dielectric materials, such as water based liquids, solids, ammonia, in vessels up to 165 ft(50 m).Low dielectric ( ) materials, such as liquefied gas, oil and solids, in vessels up to 82 ft (25 m).Extreme temperatures and pressuresThe Rosemount 5300 Series have heavy-duty probe options with multiple layers of protection to meet applications from boilers to cryogenics.

The single lead is the preferred choice for most applications. With the 5300 superior performance it is possible to use single probes in more applications. This means lowered costs, less maintenance, and reduced inventory.
