Melbourne, Australia based company ellenex released a low power, battery operated ultrasonic non-contact level sensor which they call DUS2. ellenex's DUS2 has many benefits over traditional devices which require power cables or other connection methods. The battery operated design makes this device easy to install in remote locations with no need for a connected power supply, making it perfect for applications like measuring flow rates and flood levels when there are restrictions on cable length. ellenex serves different industries with their sensor solutions, including:
- Agriculture
- Water and Utility
- Oil and Gas
- Logistics
- Mining
Oil and ellenex’s wireless sensor solution the DUS2, a MaxBotix WR sensor is the sensing element in their LPWAN solutions. ellenex's LPWAN / MaxBotix WR sensors are designed to be installed on the outside of tanks or containers for reliable level measurement with an accurate digital reading. These devices can monitor liquid surface heights by sending out short bursts of sound waves at specific frequencies which detect changes in distance caused by level variations. The MaxBotix WR senses various fluids, including water and oil products such as crude petroleum, biodiesel fuel oils, gasoline fuels, ethanol alcohols and many others.This ultrasonic level sensor for diesel tank applications ensures precise monitoring.

The product is based on 3 communication technologies:
- NB IoT Cat M1 - an IoT communication protocol, which can be used for low power consumption and long battery life.
- LoRaWAN - a long-range wireless protocol for IoT, ideal for remote water tank level monitoring.
- Low Power Satellite (ready for commercialization in 2-3 months)
- Directly to the end user platform directly from the sensor
- The information can be pulled by the API
- Deliver a microservice platform (possibly rebranded for the end user)
- Water tank level monitoring in farms
- Water trough level monitoring
- Diesel tank level monitoring
- Flood monitoring
- Chemical tank level monitoring
- Open channel level monitoring
ellenex currently services more than 50 countries. Their focus market is Australia, but currently expanding into the US and European markets.
