LIGO-RS232 probe length: (700mm-6000mm)

General description 

Fuel level sensor LIGO-SERIES is designed to be used for measuring fuel a different application, in the specific conditions of each device are achieved with precision ≤1% tolerance. Currently on the market there is some type of sensor used to measure the fuel level using various technologies, such as technology reed switches, ultrasonic technology , capacitive technology. The capacitive sensor technology known as the most popular technology in this field.


  • Highly accuracy up to 99.5%.
  • Length allow cut off up to 80 % of the initial length of the measuring probe.
  • Automatic recognize new length after cutting feature (this feature can be enable or disable by software on PC).
  • Wide range working temperature from -40°C – +85°C.
  • Screen filter is mounted on the measuring probe tubes to protect measuring probe electrodes from mud and water.
  • IP67 waterproof.
  • Advanced filter algorithm and temperature compensate.
  • Configuration,update firmware through software on PC .
  • Easy to install and sealed.
