Product 3D Image Get couponsSN53A series ultrasonic flowmeter and analyser adopts the measurement principle of time difference method. It uses the sensor to send ultrasonic propagation in the flowing fluid, downstream direction of the sound wave propagation speed will increase, against the direction of the flow is reduced, in the same propagation distance there are different transmission time, according to the difference between the transmission time and the measured fluid flow rate of fluid flow rate is measured in relation to the fluid flow rate.
Fluid flow velocity is different at different locations in the pipe, and the flow velocity in the centre of the pipe is faster than the flow velocity near the pipe wall. The distribution of the flow velocity of a fluid in a pipe can be represented by a cross sectional distribution of the flow velocity. By setting up the flow meter and considering the effect of the cross-sectional distribution of the flow velocity, it is possible to calculate the average flow velocity and then derive the volume flow rate of the fluid based on the cross-sectional area of the pipe.
