SOLUTION DENSITY RECORDER MECHANISM

Upon continuous delivery of the liquid being investigated along pipe 1 into vessel 2, recording pen 5, linked by rod 4 to float 3, draws a curve showing the variation in density of the investigated liquid. The curve is recorded on a graph paper strip attached to drum 7 which rotates about its axis. Baffle plate 6 protects float 3 against the action of nonuniform flow of the liquid. Overflow a main…
