Ultrasonic flow meters that use transit-time methods to measure flow with high accuracy and reliability for a wide range of liquids and pipe sizes.
The ST501 Ultrasonic Flow Meter utilizes advanced digital signal processing technology combined with high-performance transducers and industrial-grade materials for long-term reliability in demanding environments.
Featuring a clear menu display and IP68-rated transducers suitable for harsh conditions, the ST501 offers convenient operation with high measurement accuracy based on Transit-Time technology.
TVT (Transit-Time Vortex) technology combines transit-time ultrasonics with vortex shedding phenomenon, delivering unparalleled accuracy and versatility in ultrasonic flow measurement.
This innovative integration enhances accuracy, versatility, and performance, making it suitable for various industries requiring precise flow measurements in varying flow conditions.
Insertion type ultrasonic flowmeters measure volume flow in conductive liquids and slurry in closed pipes, including acid, alkali, salt, and other highly corrosive liquids. Widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper-making industries, as well as environmental protection, municipal management, and water conservancy construction.
