Sludge profiler of crude oil tank (S.P.O.T)

Historically the only method for determining the volume of sludge in a tank has involved manually dipping with a weighted line. The dip method is restricted to the number and position of access points on the tank roof that go through into the oil, e.g. roof legs, vents, man-ways, etc. For tanks with only an inner circle of roof legs near the centre and another outer ring of legs near the tank shell it is impossible to determine the volume of sludge over most of the tank floor.
