measuring principle

The Australian Thai automated rice field water level gauge has significant advantages. It adopts non-contact measurement with the help of ultrasound, without direct contact with rice field water, avoiding sensor damage from impurities, sediment, and microbial pollution in the water, reducing maintenance costs, and not interfering with the water body and ecological environment. Its measurement accuracy is high, reaching millimeter level, which can accurately monitor small changes in water level, assist in fine irrigation management, help farmers arrange irrigation reasonably, and improve water resource utilization efficiency. At the same time, the installation is convenient and flexible, and can be installed on the edge of rice fields, embankments, or supports, adapting to complex on-site environments. The Australian Thai automated rice field water Level gauge has significant advantages. It adopts non-contact measurement with the help of ultrasound, without direct contact with rice field water, avoiding sensor damage from impurities, sediment, and microbial pollution in the water, reducing maintenance costs, and not interfering with the water body and ecological environment. Its measurement accuracy is very high, reaching millimeter level, which can accurately monitor small changes in water level, assist in fine irrigation management, help farmers arrange irrigation reasonably, and improve water resource utilization efficiency. At the same time, the installation is convenient and flexible, and can be installed on the edge of rice fields, embankments, or supports. As long as the ultrasonic transducer works vertically downwards, it can be flexibly adjusted in position according to the actual situation of the rice field, adapting to complex on-site environments.
