6 GHz Radar 10 GHz Radar 24 GHz Radar Beam width is inversely proportional to frequency and antenna diameter. Beam Angle = k ( c/f D) f = frequency c = speed of light D = Antenna diameter * Approx.. calc. of beam width at bottom of 20ft. tank.
Signal Strength is affected by beam width and antenna diameter 24 GHZ 10 GHZ 6 GHz 24 GHz 10 GHz 6 GHz Same size antenna produces different signal strengths Different Antennas are required to produce same signal strength
Frequency - condensation • Relationship between condensation and frequency • General, the thicker condensation layer the higher microwave attenuation • High frequency is attenuated more than low frequency given the same condensation layer width 26GHz 6GHz Condensation layer
The Optimal Frequency • 1/frequency ~ Beam Angle • Frequency ~ Dust, Vapour and contamination sensitivity • -------------- • Frequency increase - the sensitivity for dust, Vapour and contamination increases. • Frequency decrease - the beam angle becomes larger.

Ideally, the antenna end should be inside tank, slightly beyond nozzle • It should not be even with tank roof • Potential concerns if antenna is shorter than nozzle 10 mm 5401 5402 • Use antenna extension with caution • Performance is reduced ifplugging or deposits occur • Heavy vibrations !

Process tanks • Slightly turbulent conditions • Agitators, inlets, etc • Condensation and Vapor • Possibly foam • Pipe/Bridle installations • Isolates device from most application conditions • Low Dielectric constant liquids • To mechanically avoid turbulence Target Applications • Storage/Buffer tank • Calm or slightly moving surface • Narrow nozzle • E.g. Solvent storage, sumps, chemical storage tanks
Installation and Configuration • Mechanical • Transmitter head, Tank Seal and Antenna is delivered in one package. • Electrical • 2-wire! SAFE &Easy!
Plant Integration 275 / 375 3420
Application Example: Concentrated Black Liquor Storage: 5401, 6” • Temp: About 110 C • Dielectric of black liquor: high • Vapors; some foam • Previous technology: • Vega low frequency 6” /DN 150 flange Fill line 11 m
Application Example: Spent Caustic: 5402, 3” Tall nozzle 3” diameter Teflon window
Application Example: Foam: 5401 Example of an application where the 5401 worked beautifully!
Application- Leachate: 5401, 6” • Product: Leachate (acid waste-water containing mud etc) • Tank Height: 3.8 m • Heavy turbulence due to top-filling and agitation. Layers of mud. • Two identical fiberglass tanks. • Only one transmitter had to be configured – all the settings were transferred to the second transmitter in less than 2 minutes • Previous technologies: • GWR ( interfered w/ agitator) • DP (clogging issues)
Power Industry applications Customer : REGCO, Thailand • Process details • Fuel Storage Tank • Diesel • Rosemount 5401 with 8” cone antenna • 2 wire installation • Maintenance free • Remote configuration
Industry applications • Customer: Casco Adhesives, Kristinehamn Sweden • Customer comments: • Customer anticipated a 4-wire transmitter for this application • Reduced operation and maintenance costs Process: Mixing and cooling ofresin Tank Height: 3.5 m Pressure: Ambient Temp: 20-50 C • Continuous cooling and mixing of different solvents to get resin • Resin is a highly viscous and sticky product • Tank has two agitators to keep fluids mixed, no foam though • Baffles on the sides • Varying DC. End resin product has approximately 6. • The customer is currently using a glass window to keep track of level. Since they are moving towards an automated process in order to cut operation and maintenance costs they need to have a reliable level measurement. • A pressure transmitter has been tested but does not work sufficiently due to density variations. • Heating coils are present in the lower part of the tank.
Industrial applications Customer comment: • ”The 5400 handles the application very well”. Process: Storage tank Product: Resin, viscous and sticky Tank Height: 7 m (5 m wide) Pressure: Ambient Temp: 20-50 C DC: Water based 4 mA: 0 m 20 mA: 6.7 m 6”, DN 150 • Large angled agitator blades, moderate stirring 0.5 m above bottom • Turbulence/splashing and occasionally foam during filling • Heating coils at approximately 0.5 m above tank bottom • Storage tank for resin that holds the product before it is shipped • Currently a floating device is used that causes continuous maintenance since the wire gets stuck
