1、 Principle of Portable Doppler Ultrasonic Flow Meter
The BR-LSZ series online Doppler ultrasonic flowmeter is a measurement method based on the Doppler methodultrasonic flowmeterIt is suitable for measuring liquids and slurries containing a large amount of impurities. It can measure the flow rate of liquid outside the pipeline or use an inserted sensor for measurement. Users can choose the sensor installation method according to the site conditions. There is no need to damage or modify the pipeline during external measurement. Installation and disassembly are very convenient, saving you a considerable amount of installation and disassembly costs, and ensuring uninterrupted production processes, thus reducing the losses caused by instrument installation downtime.
2、 Characteristics of portable Doppler ultrasonic flowmeter
The BR-LSZ online Doppler ultrasonic flowmeter adopts microcontroller technology and ultra large scale integrated circuits, which make it highly intelligent and greatly improve the stability of operation, thereby ensuring the accuracy and reliability of the instrument. The outer shell of the instrument adopts an imported all plastic chassis, achieving a protection level of IP65.
