Ultrasonic Flow Meters

Ultrasonic Flow Meters

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:

  1. Two ultrasonic transducers send signals with and against the flow direction.

  2. The difference in transit time is proportional to flow velocity.

  3. The system calculates:

    • Flow rate

    • Total volume

    • Velocity

    • Heat/cooling energy (with PT100/PT1000 sensors)
