## Resumen

Hot-tapped insertion transit-time ultrasonic meter for accurate bi-directional liquid flow measurement without pipeline interruption, moving parts or pressure drop.

## Descripción

### Product Overview

The RBFM-I is installed under pressure through a hot-tap insertion probe, so the pipeline never has to be stopped or drained. Transit-time measurement covers DN80 to DN6000 with bi-directional flow from 0 to ±12 m/s and no moving parts in the stream.

Signal-quality tracking and self-adjustment keep accuracy at ±1.0% of reading above 0.5 m/s, while an optional SD-card logger records up to 64 GB of flow history.
