Level measurement in a Palm Oil tank could be a challenge some time if a tank is as tall as more than 20 m, with heating coils near tank bottom. Palm Oil in general has low dielectric constance in a range of 1.7 - 1.8, and become solidified at operating temperature below 40 degreeC or when a heater is cutoff, besides, heating coil could be a risk to cause inteference for level measurement below it.
Rosemount PRO radar with parabolica antenna is a more suitable product for such applilcation, using FMCW technology, able to handle difficult tank condition and longer measuring range, attached successful case shares more....
