The model WWLG wireless water level gauge is an integrated lowpower water level meter specially developed for long-term automatic monitoring of groundwater levels. The entire product adopts a split module with high integration and low power consumption design concepts, which can meet the needs of customers for long-term monitoring and use. It is easy to install and requires no external power supply or additional collection and transmission equipment.
The product integrates a 19000mAH large-capacity battery and collection and transmission system, and can work for 2 years. The product has stable performance and reliable quality, and requires no wiring, making installation quick and labor-saving. Water level data is uploaded to the cloud platform through NB-IOT, and water level changes can be monitored online in real time. The integrated water level meter can be used for water level or groundwater level monitoring in foundation pits, slopes, reservoir dams, river embankments, irrigation areas, tailings ponds and other scenarios.
Characteristics：
- High-integration design, integrating power supply system and data acquisition and transmission system
- Unique pressure balance design ensures the balance between the internal pressure of the sensor and the atmospheric pressure, improving system accuracy and stability.
- High-precision silicon piezoresistive pressure sensor, 0.25%F.S measuring accuracy.
- Long battery life, 19AH built-in battery, ultra-low power consumption circuit design, 50uA in sleep mode, the device works longer and can generally be used for 1 to 2 years.
- Remote online monitoring, PC and mobile data management, real-time/historical/alarm data query.
- No on-site wiring required, quick and labor-saving installation.
Application scenarios：
- Static and dynamic measurements of fluid / pore water pressures in standpipes, boreholes, embankments, pipelines, pressure vessels, reservoirs, etc.
- Ground water elevations measuring
