This technology, known as WLPI (White Light Polarization Interferometry), operates using the phase modulation of light — the most sensitive method for fiber-optic measurements. Hydrostatic pressure measurement with optical sensors enables precise long-term monitoring of liquid. In this paper, a novel liquid level sensing system is proposed to enhance the capacity of the sensing system, as well as reduce the cost and increase the sensing accuracy.
