Abstract
A method and apparatus for measuring the specific gravity of liquids in process streams by intermittently sampling the process stream and measuring the specific gravity of the sampled liquid under static conditions in a constant level overflow device by the use of a variable immersion hydrometer operatively connected to a linear voltage displacement transducer, i.e. differential transformer, whereby vertical displacement of the hydrometer results in an output voltage signal indicative of the specific gravity of the sampled liquid. Means can be provided for compensating the specific gravity for ambient and liquid temperature and for controlling and recording the specific gravity of the liquid.
