Article 1 of 10:Introduction to OUF-W Series Wall Mount Ultrasonic Flowmeters

The Kaifeng Oasis Instrument Team is proud to present an exclusive 10-part article series dedicated to the advanced features, technical specifications, and installation best practices of our OUF-W Series Wall Mount Ultrasonic Flowmeters. Starting in mid-April, this weekly publication will serve as a comprehensive resource for industry professionals seeking to deepen their understanding of this cutting-edge technology.

Over the next 10 weeks, each installment will delve into critical aspects of the OUF-W Series, from its precision engineering and user-centric design to step-by-step installation guidelines and real-world application insights. Our goal is to equip engineers, system integrators, and technical decision-makers with actionable knowledge to optimize the performance and reliability of these innovative flowmeters in diverse industrial environments.

Understanding Ultrasonic Flow Measurement
The OUF-W Series Wall Mount Ultrasonic Flowmeters by Kaifeng Oasis Instrument Co., Ltd. leverage the transit-time principle to measure liquid velocity in pipes. This non-invasive method uses paired transducers mounted on the pipe’s exterior. One transducer emits an ultrasonic signal downstream, while the other sends a signal upstream. The flow meter calculates the time difference between these signals, which correlates directly to the liquid’s velocity. This method ensures high accuracy (±1% of reading) without disrupting flow, making it ideal for water, HVAC systems, and industrial processes.

Key Advantages:

• No pipe modification: Clamp-on transducers eliminate the need for cutting or welding.
• Wide compatibility: Works with pipes from DN25 to DN6000 and fluids like water, oils, and chemicals.
• Bi-directional measurement: Detects forward and reverse flow directions.

OUF-W Series Product Overview

The OUF-W Series is designed for durability and versatility. Its wall-mounted converter integrates seamlessly into control panels or field installations. Key components include:

1. Converter: Features a 2×20-character LCD, 16-key interface, and IP65-rated enclosure for harsh environments.
2. Transducers: Choose from clamp-on (TS-2/TM-1/TL-1), insertion (TC-1), or inline models for diverse applications.
3. Temperature Sensors: Optional PT100 probes enable heat measurement (kWh, GJ) for energy monitoring.

Applications Across Industries

1. Water & Wastewater: Monitor clean water distribution, sewage flow, or pump efficiency.
2. HVAC Systems: Measure chilled/heated water for energy audits.
3. Chemical Processing: Compatible with corrosive liquids
4. Renewable Energy: Track geothermal or solar thermal fluid flow.

Why Choose the OUF-W Series?

• User-Friendly Interface: Navigate 100+ menus (e.g., M00 for flow rate, M90 for signal diagnostics) with intuitive keys.
• Robust Connectivity: Supports 4-20mA, RS485, and MODBUS protocols for SCADA integration.
• Long-Term Reliability: IP68-rated transducers and -30°C to 160°C operating range.

Getting Started

Before installation:

1. Confirm pipe material, diameter, and fluid type.
2. Select transducers based on pipe size and temperature.
3. Ensure the pipe is full and free of air bubbles.
Pro Tip: Use an ultrasonic thickness gauge to measure pipe walls (Menu M12) for precise parameter input.
