Abstract: Fluid monitoring devices (100,200,700) including an impedance sensing element (110,210,410,510,610,710,61,62,63) are provided. The impedance sensing element (110,210,410,510,610,710,61,62,63) includes a calibration portion (212, 412, 512, 612, 712) and a measurement portion (214,414,514,614,714), and the fluid monitoring devices (100,200,700) can be self-calibrated in real time based on calibration data from the calibration portion (212,412,512,612,712).
