NB-IOT Anywhere Tank Sensor
)
Knowio NB-IoT Radar Tank Level Sensor — A radar-based tank monitoring sensor for enterprises with multiple tanks across multiple sites. It reads fuel, water or waste tank levels daily and fires instant low/high-level alerts — via app, email, or a monitoring station — the moment a tank runs low or overfills. It runs on its own NB-IoT SIM, so there's no dependency on site WiFi, and a multi-year, field-replaceable battery means no mains wiring. Fits metal or plastic tanks up to 6.75m tall, installs in 30 minutes, and integrates with existing Ajax, Hikvision and Dahua CCTV for automatic snapshot confirmation on alarm.
