## Resumen

Compact non-invasive clamp-on transit-time ultrasonic meter for DN10–DN100 small pipes, measuring flow and heat with quick clip-on installation.

## Descripción

### Product Overview

The RBFM-EX3 is a compact clamp-on transit-time ultrasonic meter for small pipes from DN10 to DN100. Fixed sensor spacing makes installation plug-and-play: clip the transducers on copper, plastic, steel, iron or stainless steel pipe and the meter is ready — no cutting, no downtime, no pressure loss.

Flow rate and thermal energy are measured simultaneously, making the EX3 equally suitable for process monitoring and HVAC sub-metering in tight installation spaces.
