Technical Examples

A method of and an apparatus for measuring the thickness of one liquid layer overlying another liquid layer. The liquid thickness measuring device consists of a tubular casing, constructed of a transparent material, a resiliently biased valve member and a retaining member. The resiliently biased valve member is pivotally movable between open and closed positions to alternatively allow liquid to be sampled to enter the casing when in the open position and to seal the liquid sample when in the closed position. In operation, with the valve member disengaged from the bottom of the tubular casing, the measuring device is slowly lowered into the enclosed device. As a result, the liquid present in the enclosed structure is conductible through the opening of the tubular casing, to seek its level in the tubular member. The retaining member, which engages and holds the valve in an open position, is then released and the valve is allowed to move to the closed position. Accordingly, an accurate assessment can be made of the thickness of stratified liquid layers in the enclosed structure by measuring the thickness or height of the layers in the tubular casing.
