1. Introduction

The clamp-on ultrasonic flow meter for water is a non-intrusive device that utilizes ultrasonic technology to measure the flow rate 

of water in pipes without requiring any pipe modifications or process interruptions. This technology has gained widespread adoption

 across industries due to its ease of installation, high accuracy, and reliability.

2.Technical Specifications

Measurement Principle: Transit-time ultrasonic flow meter.

Accuracy: ±1% of reading under stable flow conditions.

Pipe Size Compatibility: Ranges from DN15 (1/2 inch) to DN6000 (240 inches) or larger.

Power Supply: DC8-36V or AC85-264V (optional).

Display: 2x20 character LCD with backlight, supporting multiple languages.

Data Interface: Isolated RS485 serial interface, supporting MODBUS protocol for integration with SCADA systems.

Temperature Range: -30°C to 160°C, depending on the sensor type.

Output Signals: 4-20mA, pulse, relay, and optional RS485 communication.

3.Applications

Water Distribution Networks: Monitoring flow in municipal water supply systems to optimize distribution and detect leaks.

Wastewater Treatment Plants: Measuring inflow and outflow rates for process control and compliance.

HVAC Systems: Balancing water flow in heating and cooling systems to improve energy efficiency.

Industrial Processes: Monitoring water usage in manufacturing, food processing, and chemical plants for cost control and resource 

management.

Irrigation Systems: Optimizing water use in agriculture to reduce waste and improve crop yields.

Peak Demand Management: Avoiding surcharges by monitoring and controlling water usage during peak periods.

4. Market Analysis

According to the 2025 edition of the Ultrasonic Clamp Flow Meter Market Research Report, the global market for ultrasonic 

clamp-on flow meters, including those for water, is experiencing steady growth driven by increasing demand for accurate and 

non-intrusive flow measurement solutions. Key market participants include Siemens, Baker Hughes, Endress+Hauser, KROHNE Group,

 Emerson, Yokogawa, and others. The water treatment industry is a significant contributor to this growth, with a focus on smart water 

management and leak detection.

5. Advantages Over Traditional Methods

Non-Intrusive Installation: Eliminates the need for pipe cutting, welding, or process shutdowns, reducing installation costs and downtime.

Wide Range of Pipe Sizes: Suitable for both small and large pipes, making it versatile for various applications.

High Accuracy: Provides reliable flow measurements under stable conditions, crucial for billing, process control, and leak detection.

No Pressure Loss: Does not obstruct the flow, ensuring no pressure drop across the meter.

Bidirectional Flow Measurement: Capable of measuring flow in both directions, useful for systems with changing flow directions.

Data Logging and Communication: Facilitates integration with SCADA systems for remote monitoring and control.

6. Case Study: Township Water Authority

A suburban township in the upper Midwest United States faced challenges in managing water demand to avoid peak limit surcharges 

imposed by the major municipal water district. By installing Siemens clamp-on ultrasonic flow meters at each of its four connections 

to the transmission main, the township was able to monitor flow rates in real-time, control usage peaks, and avoid significant surcharges.
