Introduction to the Product

Strela Fuel Level Sensor (FLS) with RS232 output interface is designed for measuring fuel and lubricant (POL) levels. It is suitable for use in vehicles and fuel depots as part of fuel monitoring and control systems.

FLS can measure fuels such as gasoline, diesel, and oil. It determines fuel levels, converts them into volume (if recalibration tables are unavailable, output is proportional to level), and transmits data over RS-232 using the Modbus or Omnicomm protocol. The sensor is compatible with display units or programmable controllers that match its electrical signal specifications.
