Q1. What is the Rosemount 3810 Ultrasonic Water Meter?
A: It is a high-accuracy, multi-path ultrasonic flow meter designed for precise liquid measurement in water distribution, industrial processes, and custody transfer applications.
Q2. How does it measure flow?
A: The meter uses ultrasonic signals transmitted across the flow path. By measuring the time difference of sound waves traveling with and against the flow, it calculates velocity and volumetric flow with exceptional accuracy.
Q3. What makes it different from traditional mechanical meters?
A: Unlike turbine or mechanical meters, the 3810 has no moving parts, which reduces maintenance, eliminates wear, and ensures long-term stability and reliability.
Q4. What accuracy can I expect?
A: The 3812 (two-path) model achieves up to ±0.2% accuracy, while the 3814 (four-path) model delivers up to ±0.15% accuracy, making them suitable for custody transfer and critical applications.
Q5. What pipe sizes are supported?
A: The 3810 series supports a wide range of pipe diameters, from 2 inches (DN 50) up to 120 inches (DN 3000), depending on the model.
Q6. Can it be used for custody transfer?
A: Yes. The 3810 series is certified to international standards (OIML R117, API, ATEX, IECEx), making it fully compliant for custody transfer of water and hydrocarbons.
Q7. What industries typically use this meter?
A: Water utilities, oil & gas, chemical processing, power generation, and large-scale infrastructure projects all rely on the 3810 for accurate and reliable flow measurement.
Q8. What are the installation requirements?
A: The meter is installed in-line with flanged connections. Proper upstream and downstream straight pipe lengths are recommended to ensure optimal accuracy.
Q9. Does it require frequent calibration?
A: No. Thanks to its ultrasonic technology and advanced diagnostics, the 3810 requires minimal recalibration and offers long-term measurement stability.
Q10. What diagnostic features are included?
A: The electronics platform provides real-time signal quality monitoring, flow profile diagnostics, and predictive maintenance alerts to ensure continuous reliability.
