TEK 766 LoRa Ultrasonic EU (868 MHz)

The Tekelek TEK766 EU is a battery-powered ultrasonic tank level sensor with an integrated LoRaWAN® radio. It provides accurate and reliable remote monitoring of liquid levels, making it ideal for tanks and containers where regular manual level checks are impractical. Using ultrasonic technology, the sensor measures the liquid level without coming into direct contact with the contents of the tank. Measurement data can be transmitted wirelessly over a LoRaWAN network to your IoT platform, enabling both periodic and continuous monitoring. Trackpac.io — Your Monitoring Platform The Dragino TEK 766 is a LoRaWAN device, which means it needs a network server and a dashboard to turn raw data into a usable view. That's what Trackpac.io provides and it comes ready out of the box: Scan the QR code included with your device to register it on Trackpac.io €18 per year per device — covers LoRaWAN connectivity, the live dashboard, alerts, and data storage No infrastructure needed — Trackpac handles the network server, data routing, and visualisation. You just watch the map. Suitable for a wide range of liquids The TEK766 EU can be used for monitoring many different types of liquids, including: Fuel, oil, kerosene and diesel Lubricants Additives DEF / AdBlue Coolants Water Waste oil Wastewater For certain corrosive or hazardous chemicals, compatibility should be confirmed with Tekelek before use. Key benefits Accurate ultrasonic level measurement Integrated LoRaWAN® connectivity Remote and continuous tank level monitoring High and low level alarms Remote configuration Easy installation Long battery life of up to 14 years, depending on configuration and usage Suitable for large-scale deployments Up to 15 km range, depending on environmental and network conditions CE and RoHS compliant Helps optimize deliveries, collections and logistics Reduces the need for manual tank inspections Supports more efficient inventory management Optimize your tank management The TEK766 EU allows you to keep track of tank levels remotely and receive regular updates without having to physically visit the installation location. This can help prevent unexpected shortages, optimize delivery schedules and improve overall operational efficiency. For businesses managing multiple tanks, the LoRaWAN connectivity makes it possible to deploy sensors at different locations and collect the data centrally through your preferred LoRaWAN IoT platform. The sensor can be configured remotely, making it particularly suitable for larger deployments where accessing individual tanks can be difficult or time-consuming. Typical applications The Tekelek TEK766 EU can be used for: Fuel tank monitoring Diesel and heating oil tanks Water tanks Wastewater tanks Industrial liquid storage Agricultural tanks Remote inventory monitoring Automated delivery planning Low-level and high-level alerts
