AZA 0871: High-Precision Water Level Indicator for Reliable Groundwater Monitoring

The AZA 0871 Water Level Indicator fromhttps://azalab.in/wp-admin/ Azalab is a critical instrument for professionals engaged in groundwater monitoring, environmental studies, hydrological investigations, and geotechnical projects. Accurate and reliable measurement of water levels in boreholes, standpipes, and wells is fundamental for understanding aquifer behavior, assessing groundwater resources, evaluating contamination plumes, and designing dewatering or irrigation systems. The AZA 0871 provides a highly efficient and precise solution for both static and dynamic water level measurements, ensuring that crucial hydrogeological data is readily available.

At its core, the AZA 0871 Water Level Indicator operates on a simple yet highly effective electronic principle. The apparatus consists of a robust, sensitive sensing probe, a durable, high-tensile strength graduated cable (often made of steel or polyethylene with embedded conductors), and a compact reel assembly housing the electronics and battery. When the probe makes contact with water, an electrical circuit is completed, triggering an immediate and distinct audible alarm (buzzer) and/or a visual signal (LED light) at the reel. The depth to the water level is then read directly from the precise markings on the cable, typically graduated in millimeters or feet.

The design of the AZA 0871 prioritizes accuracy, durability, and user-friendliness in challenging field conditions. The probe is typically slim to fit into narrow boreholes and weighted to ensure rapid descent. The cable itself is a crucial component, engineered to resist stretching, kinking, and abrasion, ensuring consistent accuracy over time. Its clear and indelible markings allow for precise depth readings, which are critical for long-term groundwater monitoring trends. The reel often features a comfortable handle, a brake mechanism to prevent cable free-fall, and a battery compartment that is easily accessible.

Applications for the AZA 0871 Water Level Indicator are widespread. In environmental monitoring, it’s used to track changes in water tables due to seasonal variations, pumping, or climate events. For geotechnical testing, it helps in assessing pore water pressures and designing foundation dewatering schemes. In hydrological studies, it aids in understanding aquifer characteristics and groundwater recharge. Furthermore, it is invaluable for routine checks in domestic and industrial water wells, helping manage water extraction and identify potential issues. While specific ASTM or IS standards might focus on the methods of groundwater monitoring rather than the instrument itself, the AZA 0871 is manufactured to meet the high performance and reliability expectations required for such critical measurements.

Azalab’s commitment to quality ensures that the AZA 0871 Water Level Indicator is built to withstand the rigors of frequent field use, offering long-term reliability and consistent performance. Its intuitive operation and robust construction make it an indispensable tool for accurate and efficient water level assessment in any hydrogeological or geotechnical investigation. For further insights into groundwater monitoring best practices and related hydrogeological principles, resources from geological survey organizations, environmental agencies, or academic texts on hydrogeology are highly recommended.

By incorporating the AZA 0871 Water Level Indicator into your field equipment, you gain a dependable and precise tool for obtaining vital water level data, enabling informed decisions in water resource management, environmental protection, and civil engineering projects.
