I-Real’s Leveltrack and RealSense 1 data loggers and sensors for measuring and monitoring surface water can be used for a wide range of applications, including measuring levels up and down streams at a weir and measuring water quality. As the data loggers operate both on battery as well as AC power, they can be used at various locations.
The advantages of the surface water data loggers are incredible.
The Leveltrack and RealSense 1 data loggers have two communication possibilities, either via 3G/GPRS or via LPWAN/LoRa.
3G or LoRa
Both the Leveltrack and the RealSense 1 are equipped with an 3G and LoRa communication module. The data is stored locally and periodically and transmitted to the main post, through which the user is kept up to date about the water level state. When the 3G/GPRS network is inadequate in its reach the option of using the LoRa technology opens up. Through the LoRa technology it is now possible to use the series of dataloggers in those areas where there is no access to the 3G/GPRS network. The LoRa technology is extremely power efficient which prolongs the battery life of the dataloggers, decreasing the maintenance of the loggers and the need for battery changes. By adding the LoRa technology to the range of already existing (3G/GPRS) communication possibilities of the loggers, the user is assured that the surface water measurement data is accurate and up to date. Both the Leveltrack and the RealSense 1 dataloggers are suitable for either private or public LoRa networks.
The Leveltrack has a cylindrical housing, specifically designed for montage into bore holes and gauges. The logger is highly suitable for absolute and relative surface water measurements as the unit is equipped with an air pressure valve and the housing has an integrated baro sensor. The inlet of the logger allows the use of a wide variety of sensors, including sensors that function on 4-20 mA, 0-10 V or puls. The 3G edition can also be connected to an energy efficient sensor which operates on the basis of energy efficient serial protocol. When the communication module is shut off the Leveltrack functions as a semi-automatic logger.
The RealSense 1 has a rectangular shaped housing. The RealSense 1 is also extremely suitable for absolute and relative surface water measurements as the logger is equipped with an air pressure valve and the housing contains an integrated baro sensor. The advantage of the RealSense 1 data logger is that besides the battery the unit is equipped to accommodate a solar panel with a rechargeable battery or the unit can be connected to regular AC. When the communication module is shut off it functions as a semi-automatic logger.
