A liquid level change indicator is described as an apparatus. which generates a visual indication when a liquid level in a controlled vessel has changed and indicates amount of change for a timed period. Operation of the instrument entails positioning the apparatus in the liquid containment vessel from a support chain. Positioning, is accomplished by a course chain adjustment, followed by a fine-threaded-nut adjustment. A float centering itself in a concentric circle sight gauge indicates initial correct monitoring position. Deviation from one of the concentric rings constitutes a liquid level change. Each concentric ring indicates a larger level change relative to the innermost sight ring per unit test time.
