1 ADT1
The ADT1 is a maintenance-free, battery operated (three conventional, high-quality lithium AA batteries), autonomous
IoT pressure gauge with battery life of up to 5 years. The robust, waterproof housing allows outdoor use in all places
where a pressure or a level must be monitored. Typical applications: Pressure monitoring (water and gas pipes), level
measurement of surface water and ground water, tanks and liquid containers.
This device can be linked with digital level sensors and pressure transmit
ters with the KELLER “ D ” and “X” low voltage
product lines.
With its wide range of water level sensors and pressure transmitters, KELLER can offer the right
solution for any measuring situation.
The device records the pressure and temperature (and optionally conductivity as
well) of the connected sensor as well as the internal measured values like barometer and temperature.
The sensor data are transmitted in real-time using LoRaWAN® radio technology. LoRaWAN® enables encrypted radio
transmission over long distance while consuming very little power. The user can obtain sensor data through KOLIBRI
Cloud from KELLER, or through the user`s own infrastructure. Visit
KOLIBRI Cloud for an insight about the data cloud
service.
