1. Working principle:

A handheld water flow meter is a device used to measure the instantaneous flow and volume flow of water in a pipeline in real time.

The device has two sensors attached to the outside of the pipe. One transducer emits ultrasonic waves and the other transducer receives ultrasonic waves. Waves travel faster when flowing in the direction of the current, and slower when traveling against the current. Flow can be accurately calculated by measuring the difference in the time it takes for waves to travel between sensors.

The meter displays results on a digital screen, or can be connected to a computer or mobile device for further analysis. It is portable, easy to operate and easy to use, and can be used in a variety of pipe sizes and materials.

Can be used in water management systems, industrial processes and agricultural applications. It helps to ensure efficient use of water resources and reduce water waste. Its precise measurements quickly identify leaks and other water flow anomalies, helping to prevent damage and save money.

2. Advantages：

Handheld ultrasonic flow meters offer a range of advantages that make them a popular choice for many applications.

One advantage, they are very portable and easy to use, making them ideal for field work or situations where a fixed installation is not required. This mobility also makes them highly versatile, as they can be used in a variety of different environments.

Advantage two, the portable water flow meter is highly accurate and reliable, ensuring efficient and precise data collection and analysis. Users can trust the readings they receive, making it an invaluable tool for research and monitoring projects.

Advantage three, they are capable of interfacing with other equipment such as data loggers or computer software. They can be easily integrated into existing systems, allowing users to access and analyze data in a more streamlined and practical manner.

Four, the meter is often more cost-effective than fixed installations, making it a popular choice for individuals and organizations on a budget. They require less maintenance and upkeep, reducing the total cost of ownership.

Overall, handheld water flow meters offer a range of advantages that make them an attractive option for anyone involved in water flow measurement and monitoring. Their portability, accuracy, versatility, and cost-effectiveness all contribute to their popularity and make them excellent measurement tools for a wide range of applications.

3. Reference table for sensor selection:

Choose the most suitable sensor according to the caliber of the pipe to be measured and the temperature of the medium.

4. Installation site：

5. Sensor installation distance and installation method:

The spacing value displayed in the menu window M25 refers to the inner spacing distance between two sensors. The actual sensor spacing should be as close as possible to the spacing value.

※ V-method installation is the most widely mode for daily measurement with pipe inner diameters ranging from 15 mm to 400 mm. It is also called reflective mode.

※ When the pipe diameter is more than 200mm, the Z method is commonly used.

※ W-method is usually used on plastic pipes with a diameter from 15mm to 50mm.

6. Calibration and warranty:

All of our flowmeters will be calibrated twice before leaving the factory. The accuracy of the ultrasonic flowmeter is guaranteed to be within ±1%, and the factory pass rate is guaranteed to be 100%.

All of our products are guaranteed for 18 months. If there is a quality problem with the product itself, we can replace the instrument with a new one for free.
