Frequently Asked Questions (FAQ)

Q1: What is the Rosemount™ 3810 Clamp‑On Ultrasonic Flow Meter?

A1: It is a non‑intrusive flow measurement device that uses ultrasonic technology to measure liquid flow rates from outside the pipe, eliminating the need to cut or penetrate the pipeline.

Q2: What types of fluids can it measure?

A2: The 3810 is designed for clean liquids such as water, oils, and light chemicals. For fluids with higher levels of solids or gas entrainment, other Emerson solutions may be more suitable.

Q3: What are the main advantages of clamp‑on technology?

A3:

1. No process interruption during installation
2. No risk of contamination or leakage
3. Minimal maintenance, since there are no moving parts
4. Flexible use for both temporary and permanent applications

Q4: What pipe sizes can the 3810 accommodate?

A4: It supports a wide range of pipe diameters (typically DN 25 to DN 1200), making it suitable for small to large pipelines.

Q5: How accurate is the 3810?

A5: Under typical conditions, accuracy is within ±1–2% of reading. For higher‑accuracy requirements, the Rosemount™ 3812 dual‑path model is recommended.

Q6: In which industries is it commonly used?

A6: Water and wastewater, oil and gas, chemical processing, power generation, and food & beverage industries.

Q7: Is it suitable for temporary flow surveys?

A7: Yes. Its clamp‑on design makes it ideal for short‑term measurements, diagnostics, and system verification, as well as long‑term monitoring.

Q8: Does it require regular maintenance?

A8: Very little. Since the sensors are mounted externally, there is no wear from the fluid, and routine checks are generally sufficient.
