Wall Mounted Type Ultrasonic Flow Meter
The wall-mounted ultrasonic flowmeter can measure the liquid flowmeter of the full pipe. It can choose the explosion-proof and intrinsically safe type, the explosion-proof grade Exd[ib]ⅡBT6, and the intrinsically safe type, the explosion-proof grade ExibⅡBT6. The measurable medium: drinking water , River water, sea water, ground water cooling water, high temperature water, sewage, lubricating oil, diesel oil, fuel chemical liquid and other homogeneous fluids.

Product features of wall-mounted ultrasonic flowmeter
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, high-voltage lines, etc.
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 rate of the previous 64 calls and power failures, and automatically memorize whether the flowmeter's working status is normal 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.
