Remote Ground Water Level Monitoring

Frequently Asked Questions

How does the Remote Ground Water Level Monitoring Solution accurately measure water table depth in narrow boreholes?

The Remote Ground Water Level Monitoring Solution utilizes a high-precision, piezoresistive submersible level sensor deployed directly down the casing to measure hydrostatic pressure exerted by the water column. For tight monitoring wells or piezometer tubes, slimline probe variants (such as the PLM2 series) are available to slide easily past drop pipes and electrical cabling. The raw pressure reading is vented via an internal tube in the Polyurethane cable to compensate for atmospheric pressure changes automatically, ensuring accurate depth readings that are encrypted and transmitted to the Ellenex Software Platform.  

What wireless connectivity option is best for extremely isolated or rural borehole locations?

The choice depends on the local coverage footprint and network goals. For widespread regional assets where public cellular infrastructure exists, the NB-IoT / LTE-M cellular variant (-N) connects directly to public mobile base towers without requiring local gateway hardware. Alternatively, for off-grid agricultural properties or remote mining sites without cellular coverage, the LoRaWAN variant (-L) uses sub-GHz radio packets to transmit data over long distances back to a local, solar-powered Ellenex Outdoor Gateway. Both variants stream data directly into the Ellenex Software Platform.  

How does the system handle rapid drawdown during active well pumping?

The Ellenex Software Platform allows operators to define variable sampling and transmission conditions tailored to active pumping schedules. While the sensor takes hydrostatic measurements at regular intervals under normal static conditions, the device firmware can automatically accelerate its transmission frequency if it detects a rapid drop in water level. This dynamic reporting flags steep drawdown cones in real time, alerting site managers to cut pump rates before cavitation, air entrainment, or pump dry-running damages expensive downhole equipment. 

Can this groundwater solution support long-term hydrogeological compliance reporting?

Yes, continuous telemetry transmitted to the Ellenex Software Platform establishes an unalterable, automated historical record of static water levels, dynamic drawdown, and seasonal aquifer recovery rates. Water managers can export clean, timestamped datasets via the Ellenex interface or set up automated reporting schedules. This eliminates human error associated with manual logbooks and provides verified data necessary for compliance with environmental protection agencies, catchment authorities, and local water allocation licenses.  

What maintenance is required to maintain 10-year battery operation in deep well installations?

The solution is designed to be virtually maintenance-free throughout its entire operational lifecycle. Housed in an IP66 UV-protected enclosure with high-grade Polyurethane cable, the hardware contains no moving parts downhole. It is powered by an internal, replaceable 3.6V Lithium ($\text{LiSOCl}_2$) battery and governed by ultra-low-power firmware that keeps the device in a deep-sleep state between measurements. Unless a physical well inspection is required, the unit continuously streams encrypted telemetry to the Ellenex platform for up to 10 years without battery replacements or routine field visits.  

How is groundwater data from the Ellenex platform integrated into regional hydrologic models?

While the system provides instant dashboard visualization, alerting, and trend charting out of the box through the native Ellenex Software Platform, it maintains an open, API-first architecture. Hydrogeologists and enterprise users can utilize Ellenex REST APIs, Webhooks, or MQTT data forwarding to seamlessly stream raw or processed water table depth telemetry into central GIS mapping software, regional hydrological modeling suites, or corporate SCADA systems.
