Rosemount 3300 Guided Wave Radar Level transmitter

The Rosemount 3300 provides reliable and cost effective level measurements in most See the source imageliquid storage and monitoring applications. Guided Wave Radar technology combined with advanced signal processing and sensitivity enables the Rosemount 3300 Series to deliver both level and interface measurement data from the same transmitter. Two-wire connections ensure easy and inexpensive installation. Features include:

  • Accurate, direct level measurement virtually unaffected by process conditions as changes in temperature, pressure, density or conductivity and handles dust, vapor and interfering obstacles
  • Minimized maintenance with no moving parts, modular design and no re-calibration required
  • Fewer process penetrations and reduced installation costs with a MultiVariable™ level and interface transmitter
  • Easy installation and commissioning through two-wire technology and user-friendly configuration
  • Easily integrated into existing HART and Modbus plant architecture.
  • High application flexibility with a wide range of process connections, probe styles , and accessories
  • Low operating cost and increased safety with robust design and high quality chambers – Rosemount 9901

Features & Benefits

Radar is a continuous level measurement technique that offers several advantages. The measurement is virtually unaffected by temperature, pressure, dust and vapor. The instrument 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. Additionally, the Rosemount 3300 Series has the following benefits:

High application flexibility allows instrument standardization
Guided Wave Radar probes to suit a wide range of applications
Probes may be cut on site to fit the tank
Handles difficult tank geometries and heavy vapour and dust
Robust modular design resulting in low operating cost and increased safety
Dual Compartment housing separates cable connections and electronics. Housing can be rotated 360° for easy read-out
Detachable transmitter head allows replacement of transmitter head without breaching the tank atmosphere
No mechanical moving parts that require maintenance and no need for re-calibration
Easy commissioning resulting in low installation cost
User-friendly PC-based Radar Configuration Tools included for easy configuration, or optional preconfigured from factory
Single assembly for quick installation
Level and Interface reading from the same transmitter only requires one tank penetration and one pair of wires
Existing cabling may be used
2-wire loop-powered with easy to access terminals


The Rosemount 3300 Series provides reliable and cost effective measurement in a number of applications where other types of loop-powered transmitters cannot be used.

Level gauging in chambers  
Guided Wave Radar is the ideal choice for measurements in chambers. 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.
Level gauging in liquified gases and ammonia tanks  
Liquid gas as LPG and other pressurized applications require maintenance free measurement equipment. Since the transmitter head can be serviced without breaching the tank atmosphere, the Rosemount 3300 Series is perfect for pressurized and volatile applications where tank opening must be minimized.
Reliable level measurements of liquids and slurries  Reliable level measurements of liquids and slurries
The Rosemount 3300 Series delivers reliable level data where even other radar transmitters fail. The high signal/noise ratio in the transmitter and the radar pulse focused along the probe helps eliminate echo interference problems.
Interface level measurement   Interface level measurement
The Multivariable™ Rosemount 3302 is the only loop-powered transmitter on the market to deliver multi-level measurement. Thanks to its advanced signal processing, it measures both top surface and interface level in tanks containing different liquids, such as oil and water.
