Premium four-path liquid ultrasonic flow meter — engineered for custody-transfer accuracy of liquid hydrocarbons per API Chapter 5.8 and OIML R117. Four measurement planes (eight transducers) with parallel-plane geometry minimize measurement uncertainty across the full flow range. Wide rangeability, exceptional linearity, and full-bore zero-pressure-drop design make it the workhorse for refining, pipeline custody transfer, and high-throughput tanker-loading applications. Same 3810 series electronics platform as the 3812 / 3818. SIL 2 capable.
