In the past, people used to monitor water levels basically by manual means. The biggest disadvantage of this method is that human factors affect the accuracy of the measurement. For example, inexperience in measurement leads to measurement errors; measurement location changes lead to measurement discrepancies.
This all affects the accuracy and reliability of the hydrological monitoring data to some extent. This is not the case with radar water level meters, which are fixed at the most suitable location for measurement, monitored 24 hours a day, with maximum accuracy and a constant and stable delivery of data.
In addition to accuracy, radar water level meters to a certain extent can also reduce the work intensity of the relevant personnel and work difficulties. Water level measurement is generally in the field, the old manual measurement methods, data can not be done in real-time, stormy weather, personnel safety is also a problem, radar water level meter automatic monitoring, remote transmission, from the fundamental solution to the above problems, improve the efficiency of work.
River levels are not fixed or vary regularly. When heavy rains come, river levels can suddenly rise or even break the banks; in the dry season, the water level can continue to fall or even the surface skin is exposed. Real-time monitoring by radar water level meters can prepare for flood and drought prevention, and reduce accidents and damage to vegetation.
Water, can be drunk, irrigated, or used to generate electricity. Water level data measurement can provide a scientific basis for decision-making on the rational use of water resources, but only if the data is accurate and consistently stable. So, in this respect, radar water level meters are essential in water level measurement.
Hydrological monitoring does not only include water levels, but also flow rates and velocities. Therefore, in addition to radar water level meters, other instruments are also used for hydrological monitoring.
