Flexim Clamp-On Ultrasonic Flow Meters

Flexim Clamp-On Ultrasonic Flow Meters improve industrial flow measurement by providing accurate, dependable measurement without process interruption. These innovative meters utilize proprietary non-intrusive technology that clamps directly onto the outside of pipelines, eliminating the need for production shutdowns or pipeline modifications.

FLUXUS is designed for advanced process measuring in a variety of complex industrial applications. FLUXUS sets the industry standard for non-invasive ultrasonic flow measurement for more than 30 years in both liquid and gas applications.

PIOX offers non-invasive ultrasonic systems and wetted light refractometers. The patented measuring method ensures stable measuring results, even in the event of temperature and pressure fluctuations in harsh process environments.

Flexim Clamp-On Ultrasonic Flow Meters deliver exceptional precision across demanding operational conditions, maintaining accuracy even with varying fluid properties, extreme temperatures, and high-pressure scenarios. The robust design ensures consistent performance while maximizing plant availability and operational efficiency.
