This clamp-on ultrasonic flow meter is designed for DN32 to DN80mm piping and claims compatibility with a range of low-viscosity liquids including water, fuel, oil, and diesel. It features a non-invasive measurement method, enabling flow monitoring without cutting or altering pipelines. The device is positioned as a factory-direct product with emphasis on straightforward installation and high-quality after-sales service. It suits environments where users want non-contact measurements and quick deployment across modestly sized piping networks.

Strengths include non-contact measurement, reduced disruption during installation, and broad liquid compatibility. It’s particularly appealing for temporary monitoring on test rigs or retrofit projects where preserving pipe integrity is important. The listed temperature range supports common domestic water systems, though users should verify compatibility with any non-standard liquids. For users needing reliable, non-invasive flow data on small-to-medium pipes, this meter offers a practical balance of accuracy and ease of use.

Limitations to consider: Non-contact meters can be affected by external conditions like vibration or under-than-ideal alignment. Ensure proper sensor placement and calibration for best results. This model is best used in scenarios where pipe access is available and non-destructive measurement is a priority.
