Clamp On Ultrasonic Flow Meter
High-Precision Industrial Measurement
The Clamp-On Ultrasonic Flow Meter delivers accurate transit-time flow measurement for industrial liquids. Using a 700,000-gate industrial FPGA chip and proprietary TGA technology, it improves signal sampling and bubble tolerance, ensuring fast and precise measurements even with transient bubbles or impurities.
Non-Invasive Installation & Easy Operation
The clamp-on design allows external installation on pipes without cutting or stopping the system, preventing pressure loss and avoiding fluid contamination. Quick and simple setup saves labor and downtime, making it ideal for continuous operation in industrial environments.
Versatile Applications & Customization
Suitable for water, chemical, HVAC, food & beverage, pharmaceutical, and energy monitoring applications, it supports metal and plastic pipes (PVC, PP, PVDF) and a wide range of pipe sizes. OEM/ODM options include sensor size, flow range, output signals (4–20 mA, pulse, Modbus), and optional energy measurement (BTU/heat/cooling).
Durable Industrial Design & Data Management
Built with aluminum and industrial-grade plastics and rated IP65, the flow meter withstands vibration, impact, and harsh environments. EEPROM memory stores data for over 10 years, and the high-resolution LCD display provides real-time flow, total volume, and energy readings for reliable monitoring and process control.

What is a clamp-on ultrasonic flow meter and why is it suitable for industrial applications?
A clamp-on ultrasonic flow meter is a non-invasive flow measurement device that uses transit-time ultrasonic technology. It clamps externally on pipes, measuring flow without contacting the liquid. This prevents pressure loss, avoids contamination, and allows installation without stopping industrial pipelines. Ideal for water, chemical, HVAC, food & beverage, and pharmaceutical applications.
How accurate is a high-precision clamp-on ultrasonic flow meter?
Our industrial clamp-on ultrasonic flow meters deliver ±2% accuracy by default and ±1% after calibration. With proprietary TGA signal processing, the meters handle transient bubbles and impurities in the liquid, ensuring reliable flow measurement even under complex industrial conditions. Measurement range: 0.1 m/s to 10 m/s; pipe sizes DN15–DN3000 mm.
Can a clamp-on ultrasonic flow meter be customized for OEM/ODM projects?
Yes, we provide full OEM/ODM customization, including:
– Sensor size and pipe compatibility (Metal, PVC, PP, PVDF)
– Flow range and calibration
– Output signals (4–20 mA, pulse, Modbus RS485)
– Display type (LCD/LED)
– Housing protection (IP65, explosion-proof)
– Branding and packaging customization. This ensures meters meet specific industrial or energy-monitoring requirements.
How easy is the installation of a clamp-on ultrasonic flow meter?
Installation is extremely quick and non-invasive. The clamp-on sensor attaches externally to the pipe in minutes, requiring no pipe cutting or system shutdown. This reduces labor costs, minimizes downtime, and supports continuous operations in industrial plants. Optional split/transmitter designs allow flexible installation in tight spaces.
Can the clamp-on ultrasonic flow meter be used for energy monitoring or BTU measurement?
Yes, the meter can be upgraded to an ultrasonic energy meter, BTU meter, or heat/cooling meter. It measures flow and calculates energy consumption, suitable for HVAC systems, district heating, and industrial energy monitoring. Supports output via 4–20 mA, pulse, or Modbus RS485, integrating seamlessly with SCADA or PLC systems.
What are the main advantages of choosing a clamp-on ultrasonic flow meter over traditional flow meters?
– Non-invasive measurement prevents contamination and pressure loss
– Quick, easy installation with no downtime
– High precision (±1% after calibration)
– Wide compatibility: pipe sizes DN15–DN3000 mm, metal/plastic pipes
– Robust industrial design: IP65, vibration/impact resistant
