Our Ultrasonic Flow Meter is designed for accurate and stable measurement of water and other conductive liquids in full pipelines. Based on advanced transit-time ultrasonic technology and multi-path measurement, it delivers high precision without mechanical moving parts — ensuring zero wear, long service life, and minimal maintenance.
Engineered for municipal and industrial applications, the meter supports flexible installation, multiple communication interfaces, and smart data storage, making it ideal for modern water management systems.
Solid-state ultrasonic measurement with no mechanical wear. Performance is not affected by impurities in the medium.
Improves measurement accuracy and reduces installation requirements.
Supports horizontal, vertical, and inclined installation without affecting performance.
