The handheld ultrasonic flowmeter is compact and lightweight, allowing for flow measurement anytime and anywhere. The design of rechargeable batteries and a universal power supply frees you from power limitations. It adopts the principle of time difference, advanced digital correlation technology, and intelligent adaptive acoustic technology, making its measurement stability more outstanding. At the same time, it adopts proprietary sound focusing technology, which significantly enhances the signal reception and quality during continuous measurement.

The structural composition of handheld ultrasonic flowmeter

(1) The setting method of the acoustic probe. The setting method of external or internal contact sound wave probes. Gas ultrasonic flow meters generally use the insertion of receiving and transmitting transducers into the tube to the inner wall edge. Insert the device into the tube until it reaches the edge of the inner wall.

(2) The receiving method of sound waves The receiving method of sound waves. Direct type: ① Direct type: directly receiving the sound waves emitted by the probe. Reflection type: receiving the sound waves reflected by the pipe wall. ② Reflective: Receive sound waves reflected by the pipe wall. The receiving transducer does not directly receive the sound waves emitted by the transmitting transducer, and the receiving transducer does not directly receive the sound waves emitted by the transmitting transducer, but receives the sound waves reflected once or again by the pipe wall.

Handheld ultrasonic flowmeter is a handheld ultrasonic flowmeter with a fully Chinese human-machine interface, making it easier to operate. During the measurement process, there is no need to damage the pipeline, no need to stop production, the sensor does not come into contact with the measured medium, there is no pressure loss, and it also has the characteristics of battery power supply, small size, light weight, and easy portability. It can be said that it has achieved true mobile flow measurement and online detection, and is a true handheld ultrasonic flowmeter. Mainly used for flow measurement of industrial pipeline media fluids, widely applied in industries such as environmental protection, petrochemicals, metallurgy, papermaking, food, pharmaceuticals, etc.

Installation precautions

1. Observe whether the installation site pipeline meets the requirements of a distance of 10D before and 5D after the straight pipe section, as well as a distance of 30D from the pump. (D is the inner diameter of the pipeline)
2. Confirm the fluid medium inside the pipeline and whether it is full.
3. Confirm the material and wall thickness of the pipeline (fully considering the thickness of scaling on the inner wall of the pipeline)
4. Confirm the service life of the pipeline. For pipelines with a lifespan of around 10 years, even if they are made of carbon steel, it is recommended to use plug-in installation.
5. After completing the first four steps, it can be confirmed which sensor to use for installation
6. Start inputting parameters into the table body to determine the installation distance.
7. Very important: accurately measure the installation distance.
