Title: Apparatus for measuring specific gravity of liquid
Inventor: FUJIMORI ISAO
IPC: G01N9/20
Filed: 1989-08-28
Abstract: PURPOSE:To make it possible to measure the specific gravity of liquid continuously in a simple structure by arranging two tube bodies having the equal cross section and approximately equal lengths in parallel, and fixing the tube bodies. CONSTITUTION:A specific-gravity measuring apparatus A is constituted of two tube bodies 1 and 2 having the equal cross section and the equal length. Opening parts 1a and 2a are formed at one end of each bodies. The openings 1a and 2a are separated by a specified distance in the axial direction. The tube bodies are arranged in parallel and fixed to each other. Said two tube bodies 1 and 2 are connected to a differential pressure gage 3 through hoses 4. When specific gravity is measured, two tube bodies 1 and 2 are held vertically and immersed into liquid to be measured. Then pressures corresponding to the depths act on the air which is sealed in the bodies 1 and 2. Since the tube bodies 1 and 2 are connected to the differential pressure gage 3, the pressure measured in the differential pressure gage 3 indicates the value which is approximately equal to the product of the separating interval between the opening parts 1a and 2a of the tubes 1 and 2 and the specific gravity of the liquid. Therefore, the specific gravity of the liquid can be measured based on the value of the differential pressure measured in the differential pressure gage 3.
