We present a tilted fiber Bragg grating (TFBG) based fiber optic sensor for the simultaneous measurement of liquid level and temperature. Due to different responses of cladding modes and core mode in TFBG spectrum to liquid level and temperature changes, both values can be measured independently. The examined 3.5  TFBG exhibits linear liquid level, as well as temperature, responses and sensitivities of -0.4 56  0.009 dB/mm and 11.4  0.2 pm/  C respectively. Also , greater sensor applicability is proposed for liquids having lower refractive indices by using TFBG with greater tilt angle. The presented system is capable of being applied in chemical, food and automotive industries as well as, thanks to its all-fiber structure , in potentially hazardous environments where the immunity to electromagnetic fields or/and electric isolation are required
