Abstract
PURPOSE: To automatically compensate specific gravity without being affected by the temperature of a liquid to be measured, by using a syntehtic resin of appropriate expansion coefficient for a pointer.
CONSTITUTION: To measure specific gravity between 1.000, the value of an aqueous solution of 0% of ethylene glycol, and about 1.079, the value of an aqueous solution of 70% of ethylene glycol, a polyethylene with specific gravity of 0.94 and linear expansion coefficient of 14×10-5/°C is used for a pointer 1. The lowest of graduations 4 corresponds to specific gravity of 1.02 and the highest of the graduations corresponds to specific gravity of 1.07. The pointer 1 is supported on a main body 5 so that the pointer swings freely centering a fulcrum 2. A liquid to be measured is put into or out of the main body 5 thrugh an inlet/outlet port 6. When the liquid is filled in the main body 5, the pointer moves depending on the specific gravity of the liquid. The specific gravity can be read without using a temperature compensation table or effecting calculation. If values of weight percentage corresponding to those of specific gravity are graduated, the concentration of an aqueous solution can be detected. A weight 3 may be attached to the pointer 1 to adjust it depending on specific gravity.
