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.
