Ultrasonic flow meters are advanced, non-intrusive instruments that measure the flow of liquid inside a pipe using transit-time ultrasonic technology. They provide highly accurate, reliable, and maintenance-free flow measurement without cutting the pipe or interrupting the process. Ultrasonic meters are ideal for water supply networks, HVAC systems, wastewater treatment, industrial automation, and energy monitoring applications.
Modern ultrasonic flow meters—such as the GUF-1000L, TDS-100 Series, and TUF-2000 Series—use clamp-on, insertion, or inline ultrasonic transducers to measure flow across a wide pipe-diameter range from DN15 to DN6000 mm. These systems support wall-mount, handheld, and modular configurations, and provide digital communication, data logging, heat/energy measurement, and high-accuracy performance up to ±1%.
The combination of high accuracy, simple installation, and strong industrial integration makes ultrasonic flow meters an essential part of APS Technology’s process instrumentation portfolio.
What is an Ultrasonic Flow Meters?
An ultrasonic flow meter is a non-intrusive device that measures liquid flow using transit-time difference:
Two ultrasonic transducers send signals with and against the flow direction.
The difference in transit time is proportional to flow velocity.
The system calculates:
Flow rate
Total volume
Velocity
Heat/cooling energy (with PT100/PT1000 sensors)
Model | Type | Key Characteristics |
|---|---|---|
GUF-1000L | Wall-mounted | High-end FPGA processing, ±1% accuracy, IP68 sensors, heat-metering capability |
TDS-100 Series (F1, H, M) | Wall-mount, handheld | ±0.5%–1% accuracy, large pipe range, built-in data logging, IP65/IP68 |
TUF-2000 Series (B, S, SW, M, H) | Wall-mount, modular, handheld | Clamp-on, insertion, inline options; PT100 heat energy calculation; Modbus RS485 |
Available Transducer Types:
Clamp-on: Small, medium, and large sizes
High-temperature clamp-on: Up to 160°C
Insertion: For large pipes and rugged industrial use
Inline: Integrated for highest accuracy
PT100/PT1000 temperature sensors: For energy metering (cooling/heating)
Ultrasonic flow meters work on full pipes, with liquids such as water, wastewater, chilled water, chemicals, and clean industrial liquids.
Conclusion
Ultrasonic flow meters provide a flexible, accurate, and maintenance-free solution for flow measurement across water, HVAC, wastewater, and industrial applications. The GUF-1000L, TDS-100, and TUF-2000 series combine advanced transit-time technology with simple clamp-on installation, eliminating the need for pipe cutting or flow interruption.
With features such as IP68 clamp-on sensors, wide pipe compatibility, heat-energy calculation, SD card logging, and RS232/RS485 communication, these ultrasonic meters integrate perfectly into APS Technology’s automation ecosystem—including PLCs, IoT routers, and SCADA platforms.
Whether used as fixed meters, portable inspection tools, or DIN-rail modules, these ultrasonic flow meters deliver high accuracy, wide applicability, and long-term stability for modern industrial environments
