The present invention comprises a novel foldable and intrinsically safe planar coiled inductance sensor to measure liquid depths, solids in liquid depths, and two different liquids depths. This invention is used in onsite wastewater management systems (OWTS) to monitor depths of solids, oil, and effluent in a wastewater tank. The inductors are configured to allow for solids, liquids and gases to surround the coils. A number of coils are hung in series from near the OWTS tank lid to at least 18 inches below the output baffle to measure the different materials at different depths in the OWTS tank. The inductance sensors are capable of use with various materials to measure solids, oil, and effluent depths in an OWTS tank.

An arrangement and a method for controlling a dewatering process including measuring values representing operating parameters of the gravitational sedimentation device and using the values as input values for a predictive multivariable model for predicting an operating state of the gravitational sedimentation device. The disclosure further relates to obtaining reference values for the operating parameters, determining at least one predicted output for an operating parameter of the gravitational sedimentation device, and comparing the predicted output to at the reference values to determine control values that will affect changes in operation of the gravitational sedimentation device.
