Abstract
PURPOSE: To shorten measuring time and make a device smaller by a method wherein a vessel to be mesured is sealed tightly and connected to a standard vessel with a flexible tube, and a liquid level difference is obtained by measuring the hydrostatic pressure of the liquid in each vessel at a certain point.
CONSTITUTION: When vessels 2, 2' to be measured in measuring places are displaced from the specified place by Δh1, Δh2 each, the liquids are not transferred since each vessel to be measured has been sealed. Pressure P0, P1 and P2 of pressure gauges 5 become P0=P00+γ.h0, P1=P0+γ.Δh1, P2=P0+γ.Δh2, whereas, at mospheric pressure is P00, specific gravity of the liquid γ, distance between the liquid surface of a standard vessel and the pressure gauge 5 h0. Therefore, liquid level difference between the vessels becomes Δh1=(P1-P0)/γ.Δh2=(P2-P0)/γ. The liquid pressure P0, P1 and P2 in the portion of pressure gauge detected by the gauge 5 is converted into an electrical signal so as to introduce it to a multi-point perpendicular position detector 8, then liquid level difference is calculated by comparing the value obtained with pressure value in the standard vessel 1 in a computing section 10, and the result is displayed in a displaying section 11. By so doing, measurement can be made by a compact device in a wide range for a short time.
