Portable Ultrasonic Flow Meter

Débitmètre portable à ultrasons

  • It is used to process the measurement data recorded in the built-in memory of the ultrasonic flowmeter or the external SD card, including functions such as tabulation, statistics, data analysis, report printing, and flow curve creation.

Détail

Working Principle

When the ultrasonic beam propagates in the liquid, the flow of the liquid will cause a slight change in the propagation time, and the change in the propagation time is proportional to the flow rate of the liquid. At zero flow, the time required for the two sensors to transmit and receive the sound waves is exactly the same (the only technology that can actually measure zero flow). When the liquid flows, the sound wave transmission time in the countercurrent direction is greater than the sound wave transmission time in the downstream direction.

Typical Application

Portable/handheld ultrasonic flowmeters (energy meters) are used to measure the flow and heat of various single uniform liquids that can conduct ultrasonic waves.
The portable/handheld ultrasonic flow meter adopts non-contact measurement method, has a large measurement range, has no moving mechanical parts, is not affected by the system pressure and harsh environment, and has been successfully used in the measurement of fluids such as water, pure water, seawater, sewage, chemical liquids, river water, fuel oil, etc. Portable/handheld ultrasonic energy meters are widely used in the measurement of system energy consumption in refrigeration, heating, heat exchangers, freezers, boilers and other industries.
