• Continuous automatic control of density of industrial solutions, suspensions, slurries without physical contact with them;
• Control of the given density of solutions (with optional temperature sensor );
Area of application
Mining, chemical, metallurgical, construction industry, nuclear fuel cycle enterprises
Operating principle
The principle of densitometer operation is based on the transillumination of the layer of controlled liquid by the flow of gamma rays and measuring its density by degree of weakening of the flow density
