Frequently Asked Questions (FAQ)
Q1. What is the Rosemount 3051L Transmitter used for?
The 3051L is designed for accurate and reliable liquid level measurement in tanks, vessels, and process systems. It uses differential pressure technology and supports HART® communication for smart integration.
Q2. How does the 3051L measure liquid level?
It measures the hydrostatic pressure created by the liquid column in a tank or vessel. This pressure is converted into a level reading, which can be transmitted digitally via HART® or analog 4–20 mA signals.
Q3. What industries commonly use the 3051L?
It is widely applied in oil & gas, chemical, water & wastewater, food & beverage, and power generation industries.
Q4. What are the main benefits of using the 3051L?
- High accuracy (±0.065% of span typical)
- Reliable HART® digital communication
- Rugged stainless-steel construction with optional exotic alloys
- Flexible installation with direct mount or remote diaphragm seals
- Long-term stability and reduced maintenance
Q5. Can the 3051L be used in corrosive or high-temperature applications?
Yes. The transmitter can be configured with diaphragm seals, exotic alloys (Hastelloy, Monel, Tantalum), and high-temperature fill fluids to handle challenging process conditions.
Q6. How is the 3051L integrated into a control system?
It connects via a 4–20 mA loop with HART® digital communication, allowing remote configuration, diagnostics, and monitoring through compatible control systems or handheld communicators.
Q7. What certifications are available?
The 3051L can be ordered with hazardous area approvals (ATEX, FM, CSA, IECEx) and SIL safety certifications for use in safety instrumented systems.
Q8. How does it compare to other Rosemount transmitters?
- 3051L: Optimized for liquid level measurement with diaphragm seals
- 3051T: In-line pressure measurement
- 3051C: Coplanar platform for DP/flow/level
