Flowmeters
TL-UF Series
Ultrasonic Flow Meter
Non-invasive clamp-on and portable ultrasonic flow measurement
Key Features
- Non-invasive clamp-on installation — no pipe cutting
- Portable handheld version for survey and audit
- Bidirectional flow and energy measurement
- Wide pipe diameter range: DN15 ~ DN6000
- Suitable for clean, single-phase liquids
Product Overview
The TL-UF Series ultrasonic flow meters use transit-time technology to measure flow rate without cutting pipes or interrupting process flow. Available in fixed clamp-on, portable handheld, and insertion configurations, they are suitable for clean liquids in pipes from DN15 to DN6000. The non-invasive design makes them ideal for retrofitting existing pipelines.
