SN53A series ultrasonic flowmeter and analyzer adopt TDOA measurement
Principle. It uses the ultrasonic wave emitted by the sensor to
Propagation: the sound wave propagation speed will increase in the downstream direction and decrease in the upstream direction
The same propagation distance has different transmission time, depending on the difference between transmission time and
Measure the relationship between fluid velocity to measure the fluid velocity.
The flow velocity of fluid is different at different positions in the pipe, and the flow velocity in the center of the pipe
It is faster than the flow near the pipe wall. The velocity distribution of fluid in the pipeline can be determined by using the flow
Speed section distribution diagram. By setting the flowmeter and considering the section of flow rate
Distribution influence, so that the average flow velocity can be calculated, and then
The volume flow rate of the outlet fluid.
