Invention provides for a fluid level sensor with a guide body (10) having a float cavity (62) with a covering (63), which is mounted onto a flange (40). The flange is provided with a rib (51) to increase holding strength. A float (70) which slides along the float cavity (62) when there is a variation of the fluid level. The float cavity (62) makes point contacts with the float (70). A PCB assembly (90) placed along the guide body (10) for fluid level indication, and magnet (71) mounted onto the float (70) activates reed switch (93) of the PCB assembly (90) to indicate the fluid level.
