Fumis LevelTronic

Smart Fuel Level Monitoring for Biomass Systems

Target applications
Biomass stoves and boilers with FUMIS controllers
LevelTronic enables AUTONOMY prediction, showing the remaining combustion hours based on the current fuel level. It also ensures that combustion is safely stopped before the reservoir is completely empty, allowing for a smooth and reliable restart after refilling.

Biomass reservoirs and buffer tanks
LevelTronic provides accurate, real-time fuel level measurements. It helps you manage storage and fuel replenishment more efficiently in various biomass heating and storage systems.

Easy installation with FUMIS controllers
LevelTronic includes a connecting cable that fits directly into the FUMIS ALPHA series combustion controllers. Using the PCPRO setup tool, simply enable the LevelTronic option and set the full, warning, and empty levels, or run the automatic calibration.

General-purpose use
LevelTronic also works as a standalone sensor. It outputs a PWM signal proportional to the measured distance. This signal can be filtered to DC voltage and read with a voltmeter or an analog-to-digital converter, making it a flexible solution for custom applications.

Technical characteristics
LevelTronic is a non-contact distance sensor that uses ultrasound to measure the distance between the sensor and the surface of the material. It is designed to automatically compensate for the cone of depression that forms when material is extracted from a container. Thanks to its specific construction, LevelTronic operates reliably without the need for maintenance.
