LTL-7N LoRaWAN Liquid Level Sensor

Solution Overview:

The s5system LTL-7N is a LoRaWAN Ultrasonic liquid level sensor for Internet of Things solution. It uses non contact method to measure the height of liquid in a container without opening the container, and send the value via LoRaWAN network to IoT Server.
LTL-7N sensor is installed directly below the container to detect the height of the liquid level. User doesn’t need to open a hole on the container to be tested. The non contact measurement makes the measurement safety, easier and possible for some strict situation.

LTL-7N uses ultrasonic sensing technology for distance measurement. LTL-7N is of high accuracy to measure various liquid such as: toxic substances, strong acids, strong alkalis and various pure liquids in high-temperature and high-pressure airtight containers.
NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency,especially in deep coverage.

LTL-7N supports different uplink methods include TCP, MQTT, UDP and CoAP for different application requirement.
LTL-7N is powered by 8500mAh Li-SOCI2 battery, It is designed for long term use up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)

To use LTL-7N, user needs to check if there is NB-IoT coverage in local area and with the bands LTL-7N supports. If the local operate support it, user needs to get a NB-IoT SIM card from local operator and install LTL-7N to get NB-IoT network connection.
