Contactless radioisotope density meter IPRB-01 (the densitometer) for continuous automatic measurement of bulk density (the density) of various liquids: solutions, suspensions, slurries without physical contact with them. In addition, the densitometer in conjunction with flow slurries can be used to measure the mass flow of solid fractions of the pulps.

Feature of the IPRB-01 compared to densimeter running on other physical principles, is its ability to measure the density of matter without physical contact with them, that is, in their condition as they found the process (directly in the pipes, trays, containers and other technological aids ) if provided prietom thickness controlled fluid within the 100 ... 800 mm. Otherwise, have to intervene in tehprotses and find ways to set the densitometer to ensure that these thicknesses.

For thicknesses of 100 ... 300 mm version is also provided with inserted tube densitometer with a diameter 100 ... 300 mm to 1 m long, made of plastic (polypropylene). This makes it possible, instead of the radionuclide cesium-137 used as a gamma-emitter potassium chloride (KCl) up to 100 kg.

The basis of radioisotope gamma densitometer put - absorption method for measuring the density of the medium. Controlled environment is formed in a certain layer of constant thickness, illuminated directional (collimated) flow of "hard" gamma rays, and the degree of weakening of the flow of medium defined by its density.
