The external wall mounted ultrasonic flowmeter utilizes the principle of low voltage and multi pulse time difference, and adopts high-precision and ultra stable dual balanced signal differential transmission and differential reception digital detection technology to measure the sound wave transmission time in the forward and reverse directions, and calculate the flow velocity based on the time difference.

The wall mounted ultrasonic flowmeter mainly has the following characteristics:

1. High precision measurement: accuracy up to 1%.

2. Large measurement range: By using different types of sensors, it is possible to measure the flow rate of pipelines with diameters ranging from DN15 to DN6000mm.

3. High reliability: Adopting low-voltage and multi pulse transmission circuits, the measurement accuracy is high, and the service life and reliability are greatly improved.

4. Strong anti-interference ability: using dual balanced signal differential transmission and reception circuits, effectively resisting strong interference sources such as frequency converters, TV towers, and high-voltage lines.

5. Powerful memory function: automatically remembers the cumulative flow rate of the previous 512 days, 128 months, and 10 years, automatically remembers the time and flow rate of the first 64 power outages, and automatically remembers whether the flowmeter's working status was normal in the previous 32 days.

6. Support heat measurement: Equipped with a temperature sensor, it can achieve heat measurement.

7. Support SD card storage: Optional SD card storage can achieve massive storage of ultrasonic flowmeter data.
