The non-contact gas level sensor, mounted on the multi-valve, provides precise measurement of the gas level in the tank and transmits information about the fuel quantity to the system controller. The sensor has no mechanical components and operates based on the Hall effect. The housing is waterproof and maintains flexibility in temperatures ranging from -40 to 120°C. The ALEX HS gas level sensor is compatible with most multi-valves in LPG systems. It works with sequential installations like ALEX OPTIMA and ALEX IDEA, as well as with controllers that support sensors with a linear voltage output range of 0-5V.
