SMART METERING SMART BUILDING SMART INDUSTRY Lev'O+ The Lev’O+ sensor allows you to know the level of tanks or cavities in percentage, to accurately monitor variations of the liquid level, and does not require knowledge of its geometric dimensions. By measuring the relative pressure of the liquid (water, fuel, oil, fertiliser, etc.), the Lev’O+ sensor transmits the data to a public or private LoRaWAN® radio network, enabling the application to establish the relationship between the analog value and the liquid level. Sensor Transmitter  Remote reading of gas, oil, lubricant, fertiliser, milk or water levels in a underground, overhead, mobile, indoor or outdoor tank.  Remote reading of water level variations; piezometer.  Optimisation of fuels distribution logistics. LoRaWAN®, Class A. Ready to install bundle with probe and transmitter. Easy to install and use. Remote level measurement probe with 5m cable: - Pressure range: 0...0.3 bar (level to 3 m). - Accuracy: +/- 0.8% of full scale. - Resolution: 0.2 of full scale. - Relative sensor 4-20mA; AtEx Ex ia IIC T4 Ga. - Small diameter body for easy installation. Measurement at regular intervals. More than 10 years of autonomy depending on configuration. IP65 sensor and soak-proof probe. Analog to digital conversion: 12 bits (4096 points). Pressure sensor CERTIFICATION  CE, RoHS, LoRa Alliance ®. The Lev'O+ sensor consists of a level probe installed at the bottom of the tank to be measured. The probe is connected via a junction box to the analog transmitter sensor: regularly, after powering up and stabilising, the sensor do the measure and then returns to standby. The sensor periodically transmits the measured relative pressure via a public or private LoRaWAN® communication network. It is possible to configure low/high thresholds on the 4-20mA interface. For instance you can setup: - One measurement every 10 minutes; if this is exceeded, an alert is sent; otherwise nothing. - Every 60 minutes, the sensor transmits a batch with the last 6 measurements. This configuration extends the life of the lithium battery. For liquid level measurement, the probe is factory calibrated for a specific height, in this case 3 metres (other levels on request): - The value 4 mA corresponds to a zero level. - The value 20mA corresponds to a level of 3 meters. The measurements in the range 4 to 20mA are transmitted to the application which has to establish the relation between the analog value and the liquid level. The probe is connected to the sensor from a junction box which ensures that the capillary tube included in the probe cable is vented, the sensor is offset to an area without AtEx requirements and/or under the best network coverage. The sensor supplies power to the 4-20mA probe for just the duration of the measurement. The battery is mounted on a holder for easy replacement.
