APPARENT DENSITY MEASURING DEVICE FOR MUD IN LIQUID, PONSER INDEX MEASURING SYSTEM OF MUD OR SLUDGE MADE TO BE CONTAINEDIN LIQUID AND METHOD OF MEASURING SAID INDEX

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.
