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:

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 applicationsrequire 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. |
