Ultrasonic Meter Type
BTU Meter / Flow Meter, Residential
uFlow 230 SERIES
1. Introduction
The uFlow 230 series ultrasonic BTU meter can be used for measuring the energy consumption in heat / cooling application for billing purpose. The measurement principle is static and based on the measurement of transit time with pair of ultrasonic transducer propagating at each other upstream and downstream. All calculation and flow measurement circuits are designed on one circuit board, thus offering exceptional accuracy and reality.
