2DU5R, derived from the words “2-dimensional ultrasonic flowmeter”, is a type of technology used to measure the flow of liquids and gases in closed systems. This type of technology is used in a variety of applications, which include hydropower engineering, water engineering, chemical engineering, metallurgy, and environmental protection, among others. The 2DU5R works by emitting ultrasonic waves through two different transducers, allowing the system to measure the speed of liquid flow in two dimensions.

2DU5R utilizes two very different types of transducers. The first type is called the Doppler Transducer, which is responsible for capturing the velocity profile of the liquid flowing in the tunnel. The other type of transducer is a contact transducer, which is used to measure the actual fluid levels in the tunnel. Both transducers must coordinate with one another in order to calculate the actual flow rate of the fluid.

The Doppler transducer emits ultrasonic waves, which are then reflected back from the particles in the liquid or gas at different speeds, depending on the direction of the flow. The reflected waves are then captured by the Doppler transducer and used to calculate the flow speed and direction. This data is then used to calculate the flow rate. The contact transducer is used to measure the actual height of the liquid or gas in the tunnel at various points in time. This information is also used to calculate the flow rate.

The Doppler transducer is one of the key components of 2DU5R technology, since it is essential for determining the velocity profile of the liquid flowing in the tunnel. To ensure the accuracy and reliability of the velocity measurements, the Doppler transducer must be placed in the correct position. A proper positioning of the Doppler transducer in the tunnel is achieved by using a series of probes which are connected to the transducer via cables in order to obtain the best position for the Doppler transducer. This ensures that the Doppler transducer detects the velocity profile of the liquid accurately.

In summary, the 2DU5R system works by combining the outputs from two different types of transducers (the Doppler and contact transducers) in order to measure the speed of liquid flow in two dimensions. The Doppler transducer measures the velocity profile of the liquid, while the contact transducer measures the actual height of the liquid in the tunnel. This information is then used to calculate the flow rate. The accuracy of the velocity measurements is obtained by correctly positioning the Doppler transducer in the tunnel using a series of probes.
