AN-203A wireless liquid level alarm

AN-203A is a wireless pressure alarm independently developed by Weichuan Technology based on the standard LoRaWAN protocol. The product consists of two parts: a data acquisition box and a liquid level sensor. The liquid level sensor adopts fully sealed submerged diffusion silicon liquid level measurement technology and is packaged in low-pressure injection molding process. The overall performance is very stable and reliable, with a range of 2-50 meters to be freely selected and an accuracy of ± 0.5% FS. The range and cable length can be customized according to customer needs; The data acquisition box is equipped with a LoRa module and a large capacity battery, coupled with an external omnidirectional antenna, which can better transmit and receive LoRa wireless signals and improve signal transmission distance. AN-203A adopts a low-power integrated design, with a device working life and service cycle of more than three years, and a significantly reduced frequency of battery replacement; The shell is designed with nylon and fiberglass material, which is sturdy and durable, supporting IP67 protection level, and can be used in harsh environmental conditions. Widely applicable for water level or liquid level measurement in fields such as property fire protection, medicine, metallurgy, power plants, mines, urban water supply and drainage, hydrological exploration, etc.
