The upgraded product of the ultrasonic liquid flow meter, the motherboard program is more stable, several unstable menus are modified, the sensor is changed to an integral casting type, the protection level reaches IP68, and it can be immersed in water for a long time. Wide application, simple installation, no need to break the pipe, no need to stop water, so that customers can easily realize flexible pipeline flow measurement. No daily maintenance is required, and reliable, drift-free measurement is provided for a long time. It uses advanced digital correlation technology and intelligent adaptive acoustic wave technology to make its measurement stability more prominent. At the same time, it uses proprietary sound focusing technology to significantly enhance the signal reception and quality of the product during continuous measurement.

Basic parameters

Ultrasonic liquid flow meter features
1. Good stability and high precision
Linearity is better than 0.5%, repeatability accuracy is better than 0.2%, measurement accuracy is better than ±1%
2. Wide measuring range, three kinds of probes are available
Different types of sensors can be used to measure the flow rate of pipes with a diameter of DN15 ~ DN6000mm
The measuring velocity range can reach -32m/s~+32m/s
With integrated structure, measurement can be completed at the measuring point, which conforms to the usage habits of most instruments, and the structure is more reasonable;
3. High protection level, high cost performance
Adopting full glue-filled waterproof technology, protection grade IP68; small size, with waterproof and explosion-proof (intrinsically safe) functions;
Local display; all types of sensors are optional;
Can be submerged 2 meters underwater
4. Multiple displays, convenient and simple operation
The primary meter can complete the measurement at the measuring point, the primary meter can cyclically display parameters such as cumulative flow, instantaneous flow, and velocity, and the secondary meter can display more than 100 menus in Chinese
The magnetic bar can be used to browse the parameters on the primary meter, and the parameters can be re-set or displayed in Chinese through the secondary meter, which is convenient and simple to use.
5. Support Chinese and English menu
Different versions of flow meters can support Chinese or English menus
6. High reliability
Using low-voltage, multi-pulse transmitter circuit, measurement accuracy, service life and reliability are greatly improved
7. Strong anti-interference ability
Using double-balanced signal differential transmitting and receiving circuits, effectively resisting strong interference sources such as frequency converters, TV towers, and high-voltage lines
8. Powerful automatic memory function
Automatically memorize the cumulative flow of the previous 64 days, 64 months, and 5 years, automatically memorize the time and flow of the previous 64 calls and power failures, and automatically memorize the working status of the flowmeter in the previous 64 days.
9. Fast networking and long transmission distance
RS-485 bus communication is used between the primary meter and the secondary meter (or computer), using ordinary cables, the transmission distance can reach more than 1000 meters, and the networking is very convenient and fast. This transmission method has strong anti-interference ability and solves the problems of high cost, poor anti-interference ability, and short transmission distance of special cables for split ultrasonic flowmeters.
