Product Description:

Non-Invasive. High-Accuracy. Industrially Engineered.
The ST502 Clamp-On Ultrasonic Flowmeter offers precision flow measurement using cutting-edge Transit-Time Vortex (TVT) technology, designed for a wide range of pipe sizes and liquid types. With a clamp-on transducer that requires no pipe modification or contact with the liquid, this flowmeter ensures zero contamination, no pressure loss, and simplified installation.

Manufactured with durable aluminum alloy and CNC precision processing, the ST502 also features a screwless magnetic open-cover design for effortless access—ideal for technicians looking to minimize setup time. With an IP68-rated sensor and a wide diameter compatibility (1"–200"), it’s the go-to solution for versatile, clean, and accurate flow monitoring.


Key Features & Benefits:

  • Clamp-On Design:
    No need to cut pipes or disrupt flow. Installs externally—ideal for retrofit or hard-to-access systems.

  • Advanced TVT Technology:
    Combines transit-time and vortex shedding for ultra-precise measurement, even in turbulent flow conditions.

  • No Fluid Contact:
    Prevents contamination, corrosion, or leakage—perfect for sensitive or hazardous liquids.

  • Industrial-Grade Build:
    Made from high-strength aluminum alloy with CNC machining for durability and precision.

  • Magnetic Cover System:
    Patented screwless, side-opening design allows one-second access—no tools required.

  • Easy Programming:
    Built-in keypad with intuitive menu for setting pipe size, material, fluid type, and measurement units.

  • Built-In Data Logging:
    Integrated 2G SD card allows for flow data storage and historical analysis for system optimization.

  • Wide Pipe Compatibility:
    Fits pipes ranging from 1" (25mm) to 200" (5000mm) in diameter.


Technology Overview:

TVT (Transit-Time Vortex) Technology
TVT integrates transit-time ultrasonic methods with vortex shedding analysis to significantly improve accuracy across varying flow conditions—especially when transitioning between laminar and turbulent flow.


Ideal For Use In:

  • Industrial & Municipal Water Systems

  • Food & Beverage Processing

  • Chemical and Pharmaceutical Plants

  • Oil & Gas and Petrochemical Industries

  • Environmental Monitoring and Utilities
