Description

Technical Field

[0001] The utility model relates to the technical field of hydrological observation, in particular to a rectangular weir box for measuring water flow and water temperature. Background Art

[0002] In hydrological observations, water-related data is collected, and on-site measurements include water flow and water temperature. Typically, weir plates (rectangular or triangular) are used to measure water flow, and thermometers are used to measure water temperature. The weir plates are placed in the hydrological unit (channel or ditch) to be measured, and water is manually forced through the weir groove. The height of the weir is measured with a ruler (steel tape measure), and then the water flow data is calculated using a formula or by looking up water flow data in a table. The thermometer is placed in the water for a moment, and the water temperature is read after the temperature reading stabilizes. This results in fragmented work, unclear installation and calibration, and inconvenient data acquisition.

[0003] Therefore, a rectangular weir box for measuring water flow and water temperature is provided. The installation is simple, the calibration process is clear and reliable, the data can be read on site, and the operation is convenient. The box can be used as a temporary or long-term observation device. After the temporary observation is completed, the weir box can be removed and reused. Utility Model Content
