Heavy rain in Shenyang is approaching, hydrological monitoring equipment plays an important role

At 4 o'clock in the afternoon on July 10th, Shenyang's sky was dripping with large drops of rain. According to the meteorological department's forecast, Shenyang will soon receive heavy rain during the night. The deputy station chief of Shenyang Hydrometric Station also sits in front of the computer screen in the hydrological duty room to check the changes in the Weihe River water level. As the only hydrological observatory in the Shenyang section of the Hutuo River, as the key station of the National Hydrological Survey and Reporting Network, it is located at the Shenyang Hydrological Station below the Gongnong Bridge in Shenyang. Every data recorded will be used as an important hydrological data and will be preserved for a long time. .

In the corner of the duty station of the hydrological station, a computer was placed. From the computer screen, we can see the workers and peasants bridge near the bridge pier on the south bank of the river, with a painter's scale. This ruler is used to reflect the change in water level. And more advanced than the camera is the ultrasonic distance meter installed on the bridge of workers and peasants. This instrument will send out ultrasonic waves to the surface of the water. According to the ultrasonic reflection time, the water level will be calculated. Although ultrasonic waves have been used to measure water levels, traditional methods of scale measurement are still in use.

Above the computer screen is an iron box resembling a fire hydrant. Inside is the water data telemeter, the ultrasonic generator measures the data back, will show through this instrument's screen. Regarding the rain that has arrived, the working conditions of the hydrological station are not as intense and busy as the reporter expected, and it is more a calm and regular working condition.
