This device can be linked with digital level sensors and pressure transmitters with the KELLER “D” and “X” low voltage With its wide range of water level sensors and pressure transmitters, KELLER can offer the right product lines. -
Page 5: General Description / Adt1 Communication
KOLIBRI Cloud The KOLIBRI Cloud from KELLER offers simple and convenient access to your measurement data with your own personal login and SSL encryption. You can enjoy readily available data without the need to set up and maintain a database. The measurements can be displayed as graphs in no time at all and the export function allows you to download your data as Excel or CSV files. -
Page 6: Hardware
Hardware ADT1 Tube At just 43 mm in diameter, the cylindrical design of the ADT1 can simply be placed into the top of a two-inch-wide sounding tube standard in the groundwater measuring industry. It can be installed in a matter of seconds. The housing is designed to withstand condensation and temporary flooding. -
Page 7: How To Open And To Close The Housing
How to open and to close the housing To open the ADT1 Tube housing, push at the marked positions against the bottom of the housing/piston (see illustration below). The ADT1 Box can be easily opened with a Screwdriver PZ1, unscrew the four screws and carfully open the lid. -
Page 8: Connecting The Antenna
Connecting the antenna Screw the stub antenna into the corresponding SMA plug located at the top of the ADT1 and tighten by hand only. Make sure it is tight enough. CAUTION: Please only use the original accessories to prevent injuries and health risks. The Monopole antenna may have an ampli- fication of maximum 1.04dBi in the relevant frequency range. -
Page 9: Locking Unit (Tube Only)
Locking unit (Tube only) The locking unit for the ADT1 Tube with antenna cover is available in size from 2 up to 6 inches. The sealed antenna can be covered by a lockable protective cap made of robust plastic. This protects the data logger against theft and damage by people or wild animals when level measurements are being taken in the open countryside. -
Page 10: Connection Terminal For The Sensors
Connection Terminal for the Sensors The ADT1 offers the possibility to connect a low cost I C, or a more precise RS485 Sensor of KELLER. The pin assignment of the ADT1 is shown as follow: 3.9.1 Connection for X-Line (RS485-Interface) “low voltage” type only Connect the black wire to the +3.5V supply voltage and... -
Page 11: Operating Modes
ADT1 Measurement Cycle (Active Mode) During the active mode, the device periodically reads the values of the connected KELLER sensor with sampling period = 30 minutes (default, configurable) and stores the data in the internal EEPROM (RECORD). Therefore, the ADT1 supplies the pressure transmitter and reads the user-selected channels, when the values have been read out the power supply is switched off again. -
Page 12: Battery Lifetime Estimation
Battery lifetime estimation The value displayed in the “ADT1 Configuration” and the “KOLIBRI Cloud“ is the battery capacity calculated by the ADT1 as a percentage of remaining capacity. It is recommendable to change the battery if the value is less than 20%. Once the battery has been changed the value is once again shown as 99%. -
Page 13: Record Data Storage
RECORD Data Storage The record data storage offers the advantage that the measuring data doesn’t get lost if the data transfer (connection to the gateway) is temporarily out of function, the data can also be read out on site. All measured values are stored in the ADT1’s EEPROM. -

Page 20: Lorawan Settings
6.1.10 LoRaWAN Settings The parameters required for transmission can be changed in the LoRa settings. Number Description Explanation / Function Activation Method LoRaWAN offers two methods of device activation: OTAA (Over The Air) and ABP (Activation by Personalization). OTAA is the preferred method to join any LoRaWAN network. Depending on the activation method selected, the input fields are activated. -
Page 21: Activation
6.1.10.1 Activation LoRaWAN devices have a 64-bit unique identifier “Device EUI” that is assigned to the device by the chip manufacturer. However, all communication is done with a dynamic 32-bit device address “Device Address” a procedure called Activa- tion. -

Page 23: Perform Water Level Configuration With Adt1 Devices
Perform water level configuration with ADT1 devices Description This document is intended to show how to determine the installation parameters needed for the calculation of the water level, especially the installation length. At the same time the different types of water level calculation are listed. -
Page 24: Water Level Calculation Types
Water level calculation types There are essentially 3 different calculation types. 8.4.1 Water height above probe At water height above probe (E) the water column/water height above the probe is measured. 8.4.2 Depth to water At depth to water (F) the distance from the upper edge of the measuring point to the water surface is determined. For the calculation of the depth upper edge of the measuring point to the water surface the installation length B must be known. -
Page 25: Determining The Installation Length By Measuring With A Tape Measure
Determining the installation length by measuring with a tape measure The installation length (B) can be determined by measuring from the upper edge of the remote transmission unit to the level probe (marker) with a tape measure. For this purpose, the level probe must be mounted to the remote transmission unit and then laid out on the ground. -
Page 26: Determining The Installation Length With Adt1 Remote Transmission Unit
Determining the installation length with ADT1 remote transmission unit Since the ADT1 remote transmission unit has no external connector for the interface, the level measurement e must be performed with the housing open. Note that the housing length must then be added to the measurement result to obtain the correct installation length. - Page 27 Start software "ARC/GSM/ADT Configuration" and change to the Tab "Water level configuration" (assuming all other ADT1 measurement settings are done). (1) Select desired calculation method (2) Fill in the parameters (3) Select the measuring channel that is responsi- ble for the water level measurement. For...
