UA84357U - Membrane densitometer - Google Patents

Abstract

A membrane densitometer includes receiving vessel of the type of manometric column with overflow, in its lower section two membranes with solid center are fixed, compensation system for pressure of controlled medium on membrane, and measuring device. The compensation system comprises an arranged as a rectangular parallelepiped with square cross section of measuring chamber, in its opposite walls in the lower section membranes with solid centers, installed coaxially, are mounted, and inside at axis of measuring chamber a tubular branch is installed, this comprises a delivery branch pipe and a figured branch pipe with its lower end bent at angle 90 °. Delivery and figured branch pipes are connected with elastic bush placed in the centering equipment that comprises two [-shaped holders the upper ends of which are fixed on the delivery branch pipe, and the lower ones are installed in the bearings in such a way that the centers of the bearings and the middle of the elastic bush are at one horizontal axis. The figured branch pipe in zone of bent is rigidly connected to the center of the second membrane with solid center, and the measuring chamber is by means of feeding branch pipe connected to the controller-stabilizer of flow rate and air pressure.
