Product Description: Accurate. Reliable. Industrial-Grade.The ST501 Insertion Type Ultrasonic Flowmeter leverages advanced Transit-Time (TVT) technology to deliver precise flow measurement across a wide range of liquids and pipe sizes (1"–48"). Designed for easy installation and long-term reliability, this flowmeter is ideal for industrial environments requiring real-time, non-intrusive flow monitoring. Crafted with high-grade materials and housed in a robust metal case, the ST501 is built for harsh environments. Its IP68-rated transducer can withstand immersion and high humidity conditions, making it an excellent choice for rugged industrial settings. Key Features & Benefits: High Accuracy Measurement:Transit-Time and TVT technology ensure consistent and precise flow readings, even in turbulent or variable flow conditions. Non-Intrusive Installation:Insertion-style transducer minimizes pressure loss by preserving the integrity of the pipe wall. Versatile Application:Suitable for conductive liquids, slurries, and highly corrosive fluids such as acids, alkalis, and salts. User-Friendly Interface:Built-in keypad, intuitive menu navigation, and a clear LCD screen with alarm functionality make setup and monitoring straightforward. Advanced Data Logging:Store and analyze historical flow data to optimize system performance and efficiency. Wide Pipe Compatibility:Works with pipe diameters from 1" (25mm) up to 48" (1200mm), covering most industrial needs. Rugged & Durable:Industrial-grade components ensure long-lasting performance in demanding conditions. Technology Overview: TVT (Transit-Time Vortex) TechnologyThis innovative hybrid approach combines transit-time ultrasonic methods with vortex shedding detection to enhance measurement accuracy across various flow regimes—especially useful in applications with fluctuating or turbulent flows.
