Reliable and easy measurement in demanding applications

The Rosemount 3300 can provide reliable and cost-effective liquid level measurement in most liquid storage and monitoring applications. By combining guided wave radar technology with advanced signal processing capabilities and sensitivity, the Rosemount 3300 series can provide both liquid level and interface measurement data simultaneously. The two-wire connection method makes installation simple and economical. Features include:

Accurate and direct liquid level measurement is almost unaffected by process conditions such as temperature, pressure, density, or conductivity changes, and can handle dust, steam, and interfering obstacles

Minimize maintenance work to the greatest extent possible, with no movable parts, adopting modular design and no need for recalibration

Using MultiVariables ™ Liquid level and interface transmitters can reduce process pipeline openings and lower installation costs

Adopting two-wire technology and user-friendly interface for easy installation and debugging

Easy to integrate into existing HART and Modbus factory architectures.

High application flexibility, equipped with various process connectors, waveguide rod forms, and accessories

Adopting sturdy design and high-quality bypass pipes to reduce operating costs and improve safety - Rosemount 9901

Radar is a continuous liquid level measurement technology with multiple advantages. Measurement is almost unaffected by temperature, pressure, dust, and steam. This instrument has no movable parts, so it requires little or no maintenance. It can directly measure liquid level, so it will not be affected by most changes in liquid properties. In addition, the Rosemount 3300 series has the following advantages:

High application flexibility makes the instrument a standardized device

- The waveguide rod of guided wave radar is suitable for various applications

- The waveguide rod can be cut on site to meet the requirements of the storage tank

- Suitable for complex tank shapes and heavy steam and dust conditions

Powerful modular design reduces operating costs and improves security

- The dual chamber housing can separate cable connections from electronic components. The shell can rotate 360 degrees, making it easy to read data

- The detachable transmitter head can be replaced without opening the storage tank

- No mechanical movable parts and no need for recalibration

Easy debugging reduces installation costs

- A radar configuration tool with a PC based user-friendly interface for easy configuration; You can also choose to pre configure it at the factory

- Single component, can be quickly installed

- One transmitter can measure both liquid level and interface simultaneously, which means only 2-core cables and one tank nozzle are needed.

- Existing wiring can be used

- Adopting a 2-wire circuit power supply, with simple wiring

In many applications, the Rosemount 3300 series radar level transmitter provides reliable and cost-effective measurements that many other loop powered transmitters cannot match.

Liquid level gauge installed on bypass pipe

Guided wave radar is an ideal choice for measuring bypass pipes. It is not affected by density changes or bypass pipe structures, and has no movable parts, thus minimizing maintenance work to the greatest extent possible. This makes it a simple and reliable ideal alternative to float technology.

Liquid level measurement in liquefied gas and ammonia tanks

Liquefied gas (such as LPG) and other pressurized storage tank applications require maintenance free measuring instruments. Due to the fact that the transmitter head can be maintained without opening the tank, the Rosemount 3300 series is highly suitable for applications where tank openings must maintain minimal pressure and volatility.

Reliable liquid level measurement for liquids and slurries Reliable level measurements of liquids and slurries

The Rosemount 3300 series can provide reliable liquid level data in applications where other types of radar transmitters are difficult to measure. The high signal-to-noise ratio of the transmitter and the radar pulses concentrated around the waveguide rod help reduce echo interference issues.

Interface and liquid level measurement Interface level measurement

multivariate ™ The Rosemount 3302 is the only loop powered transmitter on the market that can provide liquid level and interface measurements. Due to its advanced signal processing capabilities, it can simultaneously measure the upper liquid level surface and lower interface in storage tanks containing different liquids (such as oil and water)
