  • Monitoring solids content of liquid sludges
    Patent number: 4383437
    Abstract: The solids content of a thick sludge is monitored by means of a solids content monitor located in a dilution chamber into which a predetermined quantity of sludge is deposited from a sampling chamber to be diluted by a known factor (e.g. 10) by the addition of water to a predetermined dilution level. Water is sprayed into the sampling and dilution chambers to clean their surfaces and the filling and discharge of the chambers is controlled by solenoid valves operated in an automatic sequence.
