ST502 Wall-Mounted Ultrasonic Flow Meter output is 4–20 mA, etc

The ST502 Clip-on Ultrasonic Flowmeter utilizes advanced transit-time technology to deliver precise flow measurement across a wide range of liquid types and pipe sizes. Engineered with industrial-grade materials and a robust die-cast aluminum housing, it ensures long-term reliability in demanding environments.

The clamp-on transducer design allows flow data collection simply by mounting on the exterior of the pipe — the sensor never contacts the fluid, eliminating risks of contamination, pressure loss, or leakage. A clear menu display and intuitive interface make operation and configuration straightforward.

Built on Transit-Time technology with high measurement accuracy, the ST502 is a brand-new high-end product featuring CNC-machined aluminum alloy construction and an industry-leading full-sealed magnetic side-opening design — no screws required. This convenient design truly achieves "one-second opening."

• Measures actual flow and total consumption of various liquids
• CNC machined process with magnetic open-cover technology — no screws required
• Adaptive signal processing algorithms optimize performance for accurate measurements even in challenging flow conditions
• Clear display interface with backlit LCD and alarm function for easy operation and debugging
• Transit-time ultrasonic technology enables bidirectional flow measurement by precisely timing ultrasonic signals upstream and downstream
• Built-in 2G SD card for historical flow data storage and system optimization analysis
• Built-in keypad and simple menu system for fast configuration of pipe diameter, pipe material, liquid type, and measurement units

TVT technology represents a cutting-edge approach to ultrasonic flow measurement, combining the principles of transit-time ultrasonics with the capability to harness the vortex shedding phenomenon.
