Features & Benefits

Guided Wave Radar is a continuous level measurement technique that offers several advantages. It is virtually unaffected by temperature, pressure and vapor gas mixtures. It has no moving parts and therefore requires little or no maintenance. It measures the level directly and is therefore unaffected by most fluid property changes, including but not limited to density and viscosity changes. Additionally, the Rosemount 5300 Series offers the following benefits:

Higher measurement reliability and capability resulting in improved process uptime through
Direct Switch Technology
Probe End Projection
Smart Galvanic Interface
Advanced EchoLogics and Diagnostics

Robust design resulting in reduced operating costs and safety
Dual Compartment aluminum or stainless steel housing with integrated Cooling Fins
Interchangeable transmitter head without opening the tank and no matching between head and probes
No mechanical moving parts and no need for re-calibration

Easy commissioning resulting in reduced startup costs through
Multivariable, Level and Interface from the same transmitter
User-friendly configuration tool Rosemount Radar Master with Measure-and-Learn
Rotate housing in any direction
Easy to access terminals and loop-powered
Single assembly for quick installation
Existing tank openings and cabling may be used

In addition, the 5300 hashigh application flexibility.


The Rosemount 5300 series is suitable for all types of processing industries including oil & gas production, refining, petrochemical, chemical, power, and water & waste treatment. The Rosemount 5300 offers radar level measurement benefits for a wide range of applications in these industries. Its probe guided radar signal combined with innovative engineering makes the 5300 virtually unaffected by process conditions and it has almost no installation restrictions.

Combine Level And Interface Measurement
One 5300 transmitter will measure both the
upper surface and the lower product interfacein tanks with two products such as separators, settling tanks etc. This reduces the number of tank penetrations required. Use the 5300 with a single lead probe for reliable measurement of interface in crude oil and other liquids that create build-up.
Improved Performance in Liquified Gases
Being virtually maintenance-free and unaffected by turbulence and vapor, the Rosemount 5300 is perfect for
liquid gasapplications. The transmitter head can be serviced without breaching the tank atmosphere. Superior performance enables relible operation in LNG, NGL, LPG and anhydrous ammonia tanks.
Underground Benefits
Probes that are unaffected by high and narrow openings or nearby objects are available. This makes the 5300 the best choice for
underground tanks, where the installation area is usually limited.
Minimize Risk In The Most Demanding Environments
The guided wave radar technology in the 5300 contains
multiple layers of protectionthat enable reliable performance in high temperature and pressure tanks and bridles, on refinery distillation columns, and power feed-water tanks, etc. The measurement is not affected by density variations, low reflectivity media or the mechanical configuration of the bridle and the product inlet.
Solid Performance
Rosemount 5303 has a flexible single lead probe that measures
solidswith dielectric constants as low as 1.4. The measuring range is up to 160 ft (50 m), and the transmitter has robust EMI performance. Special probes for high physical weight loads are available. Solids applications with the 5300 include powders and granules, plastics such as PVC, cement, fly ash, corn etc.
Measure In Vessels With Turbulence, Vapor And Mechanical Structures

The Rosemount 5300 delivers uninterrupted level data where others fail. With Direct Switch Technology, the reflection back from the surface is two to five times stronger compared with other guided wave radars. The result is a superior ability to handle
disturbing objects, probe coating, vapor and turbulence.
Accuracy in saturated steam applications

Saturated steam under high pressure slows down radar wave propagation giving an incorrect distance. This, together with varying pressure and/ or temperature is a challenge. The Rosemount 5300 withDynamic Vapor Compensation (DVC)automatically compensates for this and maintains the level accuracy.

Level gauging in chambers

Guided Wave Radar is the ideal choice for measurements inchambers. It is unaffected by density changes, chamber configuration and has no moving parts which minimizes maintenance. This makes it an easy and reliable substitute for displacer technology.
