Rosemount™ 3812 Two-Path Liquid Ultrasonic Flow Meter

Ideal for check metering and allocation, the economical Rosemount 3812 Two-Path Liquid Ultrasonic Flow Meter features two mid-radius, parallel-plane measurement paths that minimize measurement uncertainty caused by disturbed flow profiles. The meter is equipped with ultra-fast Rosemount 3810 Series Electronics that further enhance measurement stability and accuracy by minimizing sensitivity to changes in the flow profile, solids and/or entrained air. The intuitive operator interface within MeterLink™ Software helps operators identify costly flow disturbances and meter performance issues in real time to improve measurement and maintenance practices.
