LEVEL MEASUREMENT A tank sensor system has been developed to measure the oscillating water column. The Teflon coated diaphragm with a large surface and special pressure transfer technology to the epiezoresistive sensor make the Hoppe V A LV E

MEASUREMENT AND CONTROL TECHNOLOGY The developed control system combines continuously measurement of dynamic tank Level and ship’s roll movement allows a proportional water flow control. The measurement results are basis for adaptation of tank water oscillation period by tank damping modulation. The dynamic control system ensures a harmonic tank water oscillation and lead so also to a more harmonic roll motion of the vessel.
