摘要

Apparatus for the automotive measurement of the apparent density of mud or sludge contained in a liquid, and a system for the automatic measurement of the PONSAR index and a process for measuring said index. The apparent density of one liter of clarified liquid is obtained with the aid of electronic means for measuring the immersion difference, in a clarified liquid reservoir, of a bottle successively filled with mud and clarified liquid. Detection means make it possible to measure the mud volume decanted or settled in 1/2 hour in a cylinder filled with one liter of mud-containing liquid and 1.5 liters of clarified liquid. Thus, the calculation of the volume/weight ratio then gives the PANSAR index.
