Introduction to BYLDN-1-B Portable Doppler Ultrasonic Flow Meter

Features:
Both polluted and pure liquids can be measured. Equivalent to a high-precision Doppler ultrasonic flowmeter and a high-precision time difference ultrasonic flowmeter.  
Non contact flowmeter, external clamp installation, no need to stop flow or cut off pipelines.  
It is very easy to solve application problems that other ultrasonic flow meters cannot solve, such as oversized pipe diameters, original pipe walls, and cement lining.  
Built in data recording function, capable of recording 10 files and 65000 data points. Data can be downloaded to a computer through the RS-232 interface. The flowmeter is equipped with specialized software with a Microsoft Windows style graphical interface, which can configure parameters of the flowmeter and conduct comprehensive analysis of data.  
Simplified Chinese and English bilingual windows, suitable for the needs of different users.  
Built in flowmeter calibration function, providing quick and convenient operation.  
Having years Month The daily traffic accumulation function can record the accumulated traffic of the previous 5 years and this year, the previous 12 months and this month, the previous 31 days and today.  

Principle:
Any liquid flowing in a pipeline is subject to discontinuous disturbances, which can be suspended solid particles, bubbles, or interfaces caused by fluid disturbances. This disturbance causes a frequency shift △ f in the reflected ultrasonic waves, which is a linear function of the flow velocity. By measuring the frequency shift △ f, the flow velocity (or flow rate) inside the pipeline can be measured.
Typical applications:
Sewage, raw water, circulating water, pulp, mud, crude oil and tap water, purified water, acidic and alkaline liquids, chemical raw materials, seawater, etc. On site flow verification; On site calibration of other flow meters.
