Autonomous Loggers

Keller America provides a perfect marriage of proven pressure sensor technology and advanced microprocessor-based electronics to produce a range of autonomous loggers. The DCX family of water level loggers is ideal for shallow or deep well water logging applications. Combining a water level logger with a temperature data logger, these instruments are designed and constructed to provide years of trouble-free service under the most demanding conditions. Keller’s DCX family of submersible water level and temperature data loggers are up to the task. The GSM-2 logger integrates a GSM unit that sends the logged data by E-Mail (Internet connection over GPRS) or SMS. This data transfer works both ways, from and to the GSM-2 module, allowing remote data read-out and configuration. The battery powered GSM-2 main applications are level measurements in groundwater, wells, tanks, drilling holes, water supply and wastewater.
