The sensor in the water.
A pressure sensor records the groundwater level. Temperature, conductivity or other parameters can be added depending on the task.
Groundwater & monitoring wells
Keep track of changes below the surface. Monitor groundwater continuously with sensors, data loggers and software selected for your monitoring site.

From measurement to decisions
Measure. Connect. Understand.
Sensors, data loggers and analysis work together as a system. The equipment is selected for your measurement task and location.
The logger on site.
The logger stores the readings. Retrieve them via Bluetooth or transmit them over the mobile network with the Web LTX.

What we measure.
Groundwater gauge networks are the largest field of application by volume in water management. Aquatos mini or Web LTX measure the groundwater level via a pressure transducer in the gauge tube — read out locally over Bluetooth or in real time over cellular. Logger, chamber cover, casing and desiccant are part of our delivery; civil works are handled by the contractor.
- Groundwater levelpressure transducer in a 1″ or 2″ gauge tube, small ranges for high resolution
- Above & below groundvisible stainless build-up or below-ground chambers
- Multi-aquifer set-upsseveral transducer strings per depth, separate logger per aquifer
- Water temperature & conductivityoptional on the same logger via SDI-12
- Read-outlocally over Bluetooth (mini/nano) or in real time over LTE-M (Web LTX)
Water quality from the same well.
Alongside the groundwater level, we capture the chemical status right inside the monitoring well. For the quantitative and chemical status of groundwater bodies under the EU Water Framework Directive, continuous records give a far more complete picture than spot-date sampling.
- Electrical conductivitycompensated to 25 °C — an indicator of salinisation, intrusion and contaminant plumes
- pH & redoxchemical status, contaminated-site and landfill monitoring
- Nitrateoptical (UV) or ion-selective, for nitrate and nitrate-vulnerable-zone monitoring

Where groundwater loggers work.
From a nationwide state monitoring network to a single dewatering site — the same hardware, configured differently for each task.
- State networks & WFDarea-wide hydrographs for quantitative status, ready for ZRXP/WISKI ingest
- Groundwater quality & nitratechemical status, drinking-water protection and nitrate-vulnerable zones
- Excavation & dewateringmonitor drawdown, evidence preservation on neighbouring structures
- Contaminated sites, landfill & miningcontaminant plumes, leachate, mine-water rebound
- Geothermal & heat pumpsthermal influence in the aquifer (VDI 4640)
- Coast & saltwater intrusionEC gradient, density correction, freshwater-equivalent head
Methods & standards.
Monitoring wells built to DVGW W 110 / W 111, construction and development to DVGW W 121; sampling in the sense of DIN EN ISO 22475-1. Suitable for spot-date readings as well as continuous recording. In fissured and karst aquifers, point gauges must be chosen with care — stratification sensing helps here. We capture the groundwater level with a vented gauge sensor (pressure compensated through the vent tube) or with an absolute sensor and separate barometric compensation; for saline or deep groundwater we apply the density correction.
From the field
Field examples.
Mine-water monitoring in the Ruhr areaAquatos Web data loggers monitor water level and conductivity in decommissioned shafts for RAG — probes on cables of up to 800 m.
What's under the metal cover? A flush-mount monitoring station.Unremarkable on the pavement, complete underneath: an Aquatos Web logger with rod antenna, vandalism-safe in a flush-mount chamber. Up to ten years of battery life at daily transmission.
Six gauges, one logger — 24-channel multi-level monitoring in a manholeSix parallel level measurements at one site with a single data logger: with its 24 SDI-12 channels, Aquatos Web LTX reads up to 24 sensors simultaneously. Here six pressure sensors, protected by concrete rings with a signal-permeable plastic cover — compact, cost-efficient, field-proof.
