ST502 Ultrasonic Flowmeter with Clamp-on Transducers and Transit-Time Technology for Accurate Water Treatment Flow Monitoring via RS485

Ultrasonic flow meters that use transit-time methods to measure flow with high accuracy and reliability for water treatment and flow monitoring applications.

The ST502 Ultrasonic Flow Meter utilizes advanced digital signal processing technology to deliver precise flow measurement for a wide range of liquids and pipe sizes. Engineered with high-performance transducers and industrial-grade materials, this instrument ensures long-term reliability and maintenance-free operation.

Featuring an intuitive menu display and clamp-on transducers, the ST502 offers exceptional flexibility across diverse applications. Based on Transit-Time technology, this non-invasive flowmeter collects data by clamping onto the exterior of pipes, eliminating contact with fluids and preventing contamination, pressure loss, or leakage.

• Measures actual flow and total consumption of various liquids
• CNC machined construction with magnetic open cover technology (screw-free design)
• Adaptive signal processing algorithms for accurate measurements in challenging conditions
• Clear LCD display with alarm functions for easy operation and debugging
• Transit-time ultrasonic technology enables bidirectional flow measurement
• Built-in 2G SD card for historical flow data analysis and system optimization
• Integrated keypad and simple menu system for quick configuration

The ST502 features a premium aluminum alloy construction with CNC processing and industry-leading full-sealed iron-absorbing side-opening technology, eliminating screws and enabling "one-second opening" convenience.

TVT technology represents a cutting-edge approach to ultrasonic flow measurement, combining transit-time ultrasonics with vortex shedding phenomenon detection. This innovative integration enhances accuracy, versatility, and performance, making it ideal for applications requiring precise measurements in varying flow conditions.

The device employs ultrasonic transducers installed on the pipe exterior (clamp-on) or inserted in-line. One transducer sends ultrasonic pulses downstream with the flow, while another sends upstream against the flow. The time difference between signals is directly proportional to flow velocity.

The ST502 Fixed Ultrasonic Flow Meter offers multiple communication and output options for seamless integration into industrial control systems, enabling real-time data acquisition, remote monitoring, and flow process control.
