The device DL-PR26 enables remote monitoring of water level in open water, fill level of tanks, groundwater level and various other applications. It measures the pressure at the sensor head relative to the pressure at the cable end (device enclosure). When the sensor head is placed under water (or any other liquid), the relative pressure indicates the depth of the sensor head. In water, the relative pressure of 1 bar equals to a depth of approximately 10 m.
The device also records the temperature of the sensor head. The temperature reading is used for temperature compensation.
Sensor data are transmitted in real-time using LoRaWAN® radio technology. LoRaWAN® enables encrypted radio transmissions over long distances while consuming very little power. The user can obtain sensor data through Decentlab’s data storage and visualization system, or through the user's own infrastructure.
