ALEVEL 1F5 . User Manual
2 Product overview
ALEVEL 1F5 is a smart LPG tank sensor that provides wireless communication either
autonomously with IoT (LPWAN) technologies or with external gateway. OKO 5575
battery powered is a recommended gateway that collects data from up to 6 ALEVEL
1F5 devices in range. ALEVEL 1F5 is engineered for direct & easy installation on
various types of LPG tanks. Its own mechanical dial fits typical float arm level gauges.
2.1 Operating Principle
ALEVEL 1F5 reads LPG level in tanks and sends the data periodically over radio link.
The movement of the arm (1) results in the circular motion of the magnet (2) and
the change of magnetic field - ALEVEL reads the magnetic field direction based on
the Hall Effect. Obtained value is converted to an output that is indicative of the
float arm position and hence the amount of fuel contained within the tank.
Additionally, the
built-in
mechanical level
indicator allows
immediate
visual readout
regardless the
electronics (3).
