Page 3: Product Overview
Product overview The data loggers in Series DCX are autonomous, battery-powered data collectors which can measure the water level (water column, i.e. pressure) and temperature over lengthy periods. Series DCX is designed for level measurements and is generally used for long-term data acquisition in applications with brackish water, salt water or fresh water. -

Page 6: General
General information Fluctuations in the groundwater level (or the levels of other fluids) can be determined and located precisely by measuring the prevailing (hydrostatic) pressure at a defined depth below the surface of the water. To convert the pressure [bar] into the water column level [mWS], it is only necessary to know the density of the fluid. -
Page 7: Level Measurements In Closed Receptacles
Absolute measurement method (SG) With the absolute measurement method, the prevailing total pressure on the level sen- sor is determined (= air pressure + hydrostatic water pressure). To compensate for the influence of fluctuations in air pressure, a second data logger is positioned on the surface as a barometer. -
Page 8: Functionality Of The Series Dcx Data Logger
Functionality of Series DCX Autonomous data loggers in Series DCX record the values measured for pressure and temperature together with the time of each measurement. The following types of recording and initial conditions are supported: Recording interval Constant Interval ≥ 1 second... -

Service and Support For service and support, please contact your local dealer or contact us at www.keller- druck.com Guidelines on safe and efficient use • Treat the product with care and keep it in a clean place that is free of dust. -
Page 10: Warranty Conditions
KELLER’s instructions. Data security KELLER assumes no responsibility for data loss of any nature, and shall not pay com- pensatory damages in case of data loss. Data stored in the product may be lost if the product is repaired or replaced. -
Page 11: Fitting Instructions
Fitting instructions Requirements for the location The DCX logger unit is installed in a stable position at the measurement location in order to record a groundwater level. • If the logger is fully sunk into the ground (e.g. in a sewer shaft), free movement of... -
Page 12: Water Level Configuration
The DCX logger can be connected locally to a laptop via the interface converter cable. The Logger 5 software can now be used to configure the device or to transmit the measurement data stored in the DCX to the laptop. -
Page 13: Installation Of Relative Data Logger (Vg Versions)
Installation of relative data logger (VG versions) Ambient pressure is compensated physically on VG versions. The ambient pres- sure is fed to the back of the pressure sensor on the level sensor, via a capillary tube integrated into the sensor cable. -
Page 14: Dcx Time
The DCX is configured and read locally. The DCX is fitted in the measuring point and is connected to a laptop via the interface converter cable. • The Logger 5 Software Manual is available at www.keller-druck.com Installing the software Only connect the DCX and the converter cable to your computer after the software has been installed •... -
Page 15: Verifying Measured Data
Verifying measured data Ongoing measurements can be read out with no need to interrupt the measurement sequence. As you read ongoing measurements, you can set a flag (the measurement in progress will be terminated and a new measurement will be started immediately) or you can con- tinue the ongoing measurement. -

Page 18: Ventilation Diaphragm
Ventilation diaphragm (for VG versions only) The diaphragm used for ventilation generally requires no maintenance. The ventilation function of the diaphragm is impaired by matter adhering to or contami- nating the ventilation aperture, or by contact between the diaphragm and solvents, to such an extent that it may be necessary to replace the diaphragm. -
Page 19: Cleaning
Cleaning If the data logger is used in severely contaminated media, the pressure sensor must be checked for contamination from time to time, and must be cleaned as necessary. Never use sharp-edged tools such as screwdrivers, and never apply pressure at any point on the diaphragm. -
Page 20: Calibration
