Rosemount 3301 Level Transmitter Vs Rosemount 5301 Level Transmitter

The Rosemount 3301 Level Transmitter and Rosemount 5301 Level Transmitter are GWR level transmitters that utilize GWR technology to measure liquid levels. So, what is the difference between the rosemount 3301 guided wave radar level transmitter and the rosemount 5301 guided wave radar level transmitter? How to choose between the two? We will answer these questions today for the engineers and the plant maintenance people who want to know the distinctions between these two devices.

Guided Wave Radar level transmitters use GWR technology. The level transmitter transmits microwave pulses down a probe into the tank. At the medium surface the radar signal is partially reflected back to the transmitter. The device then uses the time taken for the signal to make a round trip to calculate the level of liquid. The GWR technology finds its application in oil and gas, the chemical industry, the wastewater industry, and the power plants.

The Rosemount 3301 radar level sensor is an entry level Guided Wave Radar transmitter providing an outstanding cost effective solution with good reliability. If you need a reliable radar measurement transmitter, the Rosemount 3301 industrial level transmitter is your choice. Has no moving parts, requires virtually no maintenance, delivers excellent reliability and is easy to install. It also supports both HART and Modbus communications and has a wide range of probe configurations, making it ideal for standard level measurement and interface measurement applications.

Rosemount 5301 smart level transmitter is a modern and sophisticated instrument, which is basically the upgrade of rosemount emerson 3301. The Rosemount 5301 has Direct Switch Technology, Probe End Projection Technology, advanced diagnostics, SIL (Safety Integrity Level) compliance and self-verification. It provides higher performance, more extensive diagnostics, greater operational flexibility and advanced safety features. It also has good resistance to extreme pressure and temperature conditions and is ideally suited to demanding situations such as low-dielectric media, long-range measurements and harsh process conditions.

The Rosemount rosemount 3301 guided wave radar is better suited for general purpose applications when the process conditions are not severe. Such applications include normal storage tanks, clean liquids, water treatment, simple interface and common process storage vessels. Oil refineries and petrochemical plants, for example, prefer the rosemount 5301 guided wave radar because it is better adapted for difficult process conditions, including high pressure and high temperature environments, low dielectric constant hydrocarbons, difficult interface measurements, and critical process control systems.

2. Performance In Temperature And Pressure:
Rosemount 3301 can withstand temperature of up to 150°C and pressure of 40 bar. Rosemount 5301 is capable of temperatures up to 260°C and pressures up to 345 bar. From this comparison data, the Rosemount 5301 is more suitable for steam vessels, high pressure separators, refinery applications, and boiler systems.

3. Signal Processing Technology 
The emerson 5301 has more sophisticated radar algorithms than the emerson 3301, including Direct Switch Technology, dynamic signal processing, greater weak-signal identification capability, improved measurement performance with low-reflectivity material, and other features.

4. Diagnostics And Safety Functions:
The Rosemount 5301 provides more advanced diagnostics and verification tools than the Rosemount 3301, such as: SIL 2 Safety Integrity Level compliance, sophisticated diagnostic software, advanced monitoring functions, verification reflectors and fault detection enhancements.

5. Communication And Integration:
Rosemount 3301 can be used with 4-20 mA, HART, and Modbus, whereas Rosemount 5301 can be used with HART, FOUNDATION Fieldbus, Modbus, and WirelessHART.

6. Measurement Performance And Accuracy:
The Rosemount 5300 level transmitter series is the only device that actually delivers reliable performance for the challenging applications involving high temperature hydrocarbons. The Rosemount 5301 level transmitter can better handle difficult process conditions such as foam, steam, turbulence, condensation and low dielectric constant media.

7. Cost:

The Rosemount 3301 transmitter is cheaper and more economical than the Rosemount 5301, as it is cheaper.

Conclusion

The level transmitter rosemount 3301 and the level transmitter rosemount 5301 are both Guided Wave Radar level transmitters that use guided wave radar technology. However, they have variances. The Rosemount 3300 series is distinguished by simplicity, dependability and cost-effectiveness and is appropriate for many typical applications. Compared with Rosemount 5300, it is more suitable for harsh operating circumstances, and has excellent process adaptability. For basic water or tank level measurements, the emerson rosemount 3301 is the best choice; for high-pressure, high-temperature situations, or essential applications with severe safety requirements, the emerson rosemount 5301 is the chosen answer.
