GROUNDWATER & LEVEL MEASUREMENT WATER MANAGER SOLUTION global, sensor.excellence

The STS Water Manager is used for high-precision and safety relevant water level measurements. It is used in terrain with a wide variety of conditions and is particularly convincing due to its accuracy, robustness and reliability. Whether groundwater or level measurement, whether with additional temperature, conductivity or pH monitoring, the WMS is used and appreciated by customers from a wide variety of industries thanks to its convenient and simple handling. Due to its modular design, the WMS offers the highest possible flexibility. Even at a later stage, the logger can be extended by...

Your automated water monitoring system The groundwater data logger WMS (Water Manager Solutions) is a complete system for measuring, storing and remote transmission of water level, water temperature or other parameters such as pH, oxygen etc. All components such as the level probe, the data logger and the communication unit fit into a 2” level tube and are therefore ideally protected. Smart monitoring system Secure data transmission On-site communication is convenient thanks to a local radio interface. The loggers can be operated, parameterised or read out from a distance of up to 30 metres...

Wireless data transmission The WMS can be parameterized and read out from a distance of up to 30 m via a 433MHz local radio interface. Quadband modem The modern, integrated quad band modem allows worldwide Internet access with all common prepaid or contract SIM cards. User-friendly design The electronics remain protected from humidity, even when replacing the battery in the field, because the battery compartment is hermetically seperated from the electronic. The battery compartment and the electronics are sufficiently sealed so that short time flooding (24 h at max. 1 meter water column) does...

Internal memory (backup) The internal data logger is capable of recording up to 250 000 measured values. Irrespective of whether these have already been transmitted or not. Remote configuration The settings can be changed at any time via the GPRS or UMTS network. Battery change Thanks to the sophisticated design, the two lithium batteries can be easily replaced by the customer on site. Battery life time 10 year lifetime with hourly measurement and daily transmission of all standard parameters. All sensor types with SDI-12 interface can be connected to the logger and configured via the software.

SENSOR SYSTEMS LEVEL & TEMPERATURE As a long-standing partner with hydrologists, STS has developed and proven itself as a specialist for monitoring river, lake and groundwater levels. In the field of water supply, STS primarily manufactures products for level and pressure regulation. These are used, among other things, for reservoir management and monitoring fresh water distribution. Measuring range: 0 . . . 5 to maximum 0 . . . 250 mHO Measuring level accuracy: ≤ ± 0.10 % FS (≤ ± 0.05 % FS on request) Compensated temperature range: −5 . . . 80 °C Temperature accuracy: typical < ± 0.3 °C...

TURBIDITY SENSOR Turbidity is the term for an optical phenomenon caused by the scattering of light by suspended (undissolved) particles present in a liquid. If a light beam hits a particle, part of the light is reflected, part is absorbed. Depending on the particle shape and surface condition, the light is scattered with varying intensity in all directions. Measuring range: 0 . . . 4000 NTU Measuring accuracy: < 5 % of measured value Temperature range: 0 . . . 50 °C CONDUCTIVITY / SALINITY The measurement of conductivity is used in drinking water treatment to check the quality of raw water...

DL.WMS.MINI The product portfolio for the water level and groundwater industry has been expanded with the DL.WMS.mini which is another highly efficient and reliable short-range radio data logger. It measures both the pressure and the temperature in the medium with an accuracy of 0.2 % FS. The system consists of a data logger and a pressure sensor mounted on the cable end. The DL.WMS.mini can be used in river, lakes, canals or ground water. cent mode and low-power hardware, the system is highly energy-saving and efficient. Due to its dimensions, the logger is suitable for installation sites from...

The DL.WMS.mini is operated as a standalone system and can, in combination with the WMS, generate a network of up to 24 loggers. In this system, the WMS acts as a kind of router and transmits the collected measurement data via GPRS or UMTS to the corresponding server. Without an additional WMS, the DL.WMS.mini is conveniently monitored and operated via local radio interface. The system can be expanded at any time even after installation. Perfect design • Slim design for wells from 2” diameter • Easily accessible battery compartment allows battery change without additional tools directly on...

Advantages of the WMS Webserver • The availability of the WMS Web Client is guaranteed around the clock (24 hours / 365 days) • The system is password-protected and the data is transmitted in encrypted form • In addition, a data record can be transmitted by email for each measurement • Overview of all measuring devices incl. their display of internal housing humidity and temperature, battery staus, last transmission and signal strength • Automatic display of measured values • Direct access to the individual raw data sets, logger parameter files and logbook which provides valuable...
