For non-contact level measurement in rough environments (sewer, water and sewage systems, rain overflow basins) with protection class IP68, the BLE radar sensor is ideal. The live data is transmitted stably with the proven remote data transmission unit. The measuring interval of 10 seconds as well as the spirit level directly on the sensor drastically increase the measuring accuracy.
The sensor has a 1.5″ inch thread for mounting on standard brackets. Installation in the difficult environment takes place without wiring. The sensor transmits the data via Bluetooth (BLE) to the remote transmission unit.
With 60 GHz non-contact radar technology, operation is maintenance-free. With a measuring interval of 10 seconds, the battery life is up to 10 years. The BLE radar sensor has a gas-tight and corrosion-resistant housing without metal parts.
The appropriately selected measurement interval is relevant to avoid measurement errors. Because only if you register an event at all, you can react to it accordingly. During a heavy rain event, water swells within minutes. Just as quickly, the event can be over again. If the measurement interval is 5 minutes, the rash may not be registered at all. If the measurement interval is reduced to one minute, the probability of missing an event is significantly reduced.
Each measurement requires energy. A faster measuring interval always means an increased energy requirement. In the case of stand-alone, battery-powered systems, the balance must be struck here. The BLE radar sensor is perfectly designed for upscale requirements in terms of measurement accuracy and fast measurements. It allows a measurement interval of 10 seconds (measurement range up to 5 m, accuracy ±2 mm) while maintaining a battery life of up to 10 years.
Water level on BLE radar sensor
Reception quality for a cellular transmission can become a challenge in manholes or ducts. Therefore, it is recommended to place the transfer unit under the manhole cover (in the sand trap, dirt trap) if possible. However, the measuring point is much deeper in the sewer.
Therefore, the BLE radar sensor is separated from the transmission unit and connected wirelessly via Bluetooth. This allows the radar sensor to be placed up to 20 meters away from the transmission unit.
Water level on BLE radar sensor
The measuring range up to 5m with a resolution of 1mm and an accuracy of ±2mm is ideally suited for a level measurement. The narrow aperture angle of 4° ensures focused and reliable measurements in the range from 0 to 5 meters. This small beam angle results in high measuring accuracy in narrow shafts and sewers.
The proven, remote transmission unit can be up to 20m away from the BLE radar sensor and the sensor can thus be placed much more targeted.
To avoid parallax during installation, there is a spirit level on the BLE radar sensor. This avoids a height-dependent falsification of the measured value.
Energy consumption is significantly influenced by the frequency of a measurement (measurement interval) and a transmission (transmission interval).
The BLE radar sensor requires only 0.6 μWh to measure and transmit a reading to the central data acquisition system. Comparable industrial sensors require 125 μWh, more than two hundred times that amount.
The measurement interval of the BLE radar sensor is adjustable. With a measurement every 10 seconds, the battery life is 10 years.
With the help of the runtime calculator, you can estimate the autonomous runtime of the application as well as the costs incurred. The actual costs and energy consumption depend on the measurement conditions, such as the reception quality and ambient temperature. Detailed information on the tariffs can be found here.
