Rosemount 3300 Series - Versatile and easy to use GWR Level Transmitters 

Reliable & effortless measurement in demanding applications

The Rosemount 3300 provides reliable and cost effective level measurements in a wide range of 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. The 3300 series is now available with a new line of innovative probes, designed to perform reliably and withstand even the toughest process conditions. Two-wire connections ensure easy and inexpensive installation. Features include:

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


1 - Guided Wave Radar probes to suit a wide range of applications including corrosive- and high temperature / high pressure environments

2 - Probes may be cut on site to fit the tank

3 - Handles difficult tank geometries and heavy vapour and dust Robust modular design resulting in low operating cost and increased safety


4 - Dual Compartment housing separates cable connections and electronics. Housing can be rotated 360° for easy read-out

5 - Detachable transmitter head allows replacement of transmitter head without breaching the tank atmosphere

6 - No mechanical moving parts that require maintenance and no need for re-calibration. Easy commissioning resulting in low installation cost

7 - User-friendly PC-based Radar Configuration Tools included for easy configuration, or optional preconfigured from factory

8 - Single assembly for quick installation

9 - Level and Interface reading from the same transmitter only requires one tank penetration and one pair of wires

10 - Existing cabling may be used

11 - 2-wire loop-powered with easy to access terminals

Applications :

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

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

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.

 

 

Measurement of solids in silos

The Rosemount 3301, although designed for liquids, may also be used in many solids applications.
