Abstract

This invention discloses an IoT water meter. A blower draws humid air from a sealed cavity into an air inlet pipe, which then enters an extension pipe. The first heating element within the extension pipe dries the humid air. The serpentine structure of the extension pipe increases the residence time of the humid air, thus improving drying. After the first drying process, the air enters a drying chamber where a drying frame absorbs moisture again. The second heating element then reheats and dries the air. This air, after three drying processes, returns to the sealed cavity through an outlet pipe, ensuring the cavity remains dry. This prevents damage to the electronic components within the sealed cavity due to moisture, reducing the likelihood of damage to the IoT water meter.
