PRE-UFM-W2 Ultrasonic Flow Meter

High-Accuracy, Non-Invasive Flow Measurement for Industrial and Utility Applications

The PRE-UFM-W2 ultrasonic flow meter is an advanced flow measurement device that offers non-contact, clamp-on technology for measuring liquid flow in closed pipelines. Designed for wall-mounted installation, it provides exceptional measurement accuracy, repeatability, and ease of setup, making it suitable for a wide range of industrial and commercial applications.

Whether you’re in municipal water systems, HVAC networks, chemical processing, food and beverage production, or metallurgy, the PRE-UFM-W2 delivers reliable performance without interrupting the flow or compromising system integrity.

✅ What Makes the PRE-UFM-W2 Stand Out?

➤ Clamp-On, Non-Invasive Design

Unlike traditional in-line flow meters, the PRE-UFM-W2 uses external clamp-on transducers that are installed directly on the outside of a pipe. This means:

• No need to cut into the pipe

• No risk of fluid leakage or contamination

• No system downtime during installation or maintenance

➤ High Measurement Accuracy

Thanks to its transit-time ultrasonic technology, the PRE-UFM-W2 can achieve a measurement accuracy of ±1% for flow rates above 0.2 m/s. It also provides repeatability of ±0.2%, ensuring stable and reliable readings even in continuous flow monitoring environments.

➤ Real-Time Data and Smart Display

The flow meter is equipped with a 2-line backlit LCD display,  Users can view live flow rate, totalized volume (positive, negative, net), and other critical diagnostics in real time.

➤ Flexible Communication & Output

The PRE-UFM-W2 supports both RS485 communication and 4–20 mA analog output, making it easy to integrate into SCADA, PLC, or other industrial control systems. Built-in data logging ensures that historical data is stored for analysis and reporting.

🔧 Technical Specifications

🔍 Installation Modes

The device allows flexible installation depending on the pipe size and application:

• V-Method: Ultrasonic wave travels twice across the pipe (for small/medium pipes)

• W-Method: Wave crosses four times (for higher sensitivity)

• Z-Method: Direct across-pipe transmission (for larger pipes)

🏭 Application Areas

• Water Supply & Wastewater Treatment
  Monitor municipal and industrial water pipelines without cutting the pipe.

• HVAC & Building Management Systems
  Measure flow of chilled or heated water for energy management and system optimization.

• Food & Beverage Industry
  Flow monitoring of beer, wine, and other process liquids without contamination risk.

• Chemical & Petrochemical Processing
  Safely measure corrosive, flammable, or aggressive liquids with no pipe penetration.

💡 Benefits of Choosing PRE-UFM-W2

• Easy and fast installation without shutting down systems

• Long-lasting sensors with low maintenance requirements

• Wide range of supported fluids and pipe types

• Accurate and reliable flow data for process optimization

• Seamless integration with control systems via RS485 and analog outputs
