3100 Ultrasonic Transmitter – Non-Contact Level Measurement for Liquids
Product introduction:
The Rosemount 3100 Ultrasonic Transmitter delivers reliable, non-contact level measurement for liquids in a wide range of industrial applications. Using advanced ultrasonic technology, it provides continuous, maintenance-free monitoring without direct contact with the process medium. With options for local display, relay outputs, and digital communication, the 3100 series ensures accurate level, volume, and open-channel flow measurement. Its corrosion-resistant construction and intuitive configuration make it ideal for water treatment, chemical storage, and general-purpose tank monitoring.

The Rosemount 3100 Ultrasonic Transmitter is designed for reliable, non-contact level measurement across a wide range of industries. Typical applications include:
Q1: What is the Rosemount 3100 Ultrasonic Transmitter used for?
A1: It is a non-contact level transmitter designed for continuous measurement of liquids in tanks, sumps, and open channels. It is commonly used in water treatment, chemical storage, and general industrial applications.
Q2: How does the 3100 measure the level?
A2: It uses ultrasonic sound waves to measure the distance between the sensor and the liquid surface. The transmitter then converts this distance into a level or volume reading.
Q3: What is the maximum measuring range?
A3: Depending on the model, the 3100 series can measure up to approximately 10 meters (33 feet).
Q4: Can it be used in hazardous areas?
A4: Yes. The Rosemount 3105 model is certified for use in hazardous areas, offering intrinsically safe operation.
Q5: What output signals are available?
A5: The 3100 series supports 4–20 mA with HART communication. Some models also include relay outputs for pump or valve control.
Q6: Is it suitable for corrosive liquids?
A6: Yes. The sensor face is made from corrosion-resistant materials such as PVDF, making it suitable for many chemical applications.
Q7: What are the main limitations of ultrasonic technology?
A7: Ultrasonic transmitters can be affected by heavy foam, vapor, turbulence, or extreme temperature variations. In such cases, radar level transmitters may be a better choice.
Q8: How is the device configured?
A8: The transmitter can be configured locally using its display and keypad, or remotely via HART-compatible handheld communicators or asset management software.
Q9: What industries typically use the 3100?
A9: Water and wastewater treatment, food and beverage, light chemical processing, and general industrial liquid storage.
Q10: How does it compare to radar level transmitters?
A10: Ultrasonic transmitters are cost-effective and easy to install, making them ideal for simple applications. Radar transmitters, however, are more accurate and reliable in challenging conditions such as high pressure, vapor, or foam.
