Abstract

The invention discloses a liquid specific gravity measuring device. The liquid specific gravity measuring device comprises a measuring platform fixed to a side wall of a container, wherein the measuring platform is provided with a first through hole and a second through hole; a first measuring rod and a second measuring rod which are the same in length and cross section extend into liquid under measurement from top to bottom through the first through hole and the second through hole respectively and freely suspend in the liquid under measurement; a first displacement sensor and a second displacement sensor which are used for detecting vertical movement are arranged beside the first through hole and the second through hole respectively; the weight of the first measuring rod is 1.5-3 times that of the second measuring rod; the first displacement sensor and the second displacement sensor are in signal connection with a PLC (Programmable Logic Controller) control module; and the PLC control module comprises a data acquisition unit, a central processing unit, a storage unit, a power supply unit and a display input unit. Through the adoption of the liquid specific gravity measuring device, the liquid specific gravity can be accurately measured in real time, and the working efficiency is greatly improved.

Description

technical field [0001] The present invention relates to a specific gravity measuring device, more particularly, the present invention relates to a device for real-time measurement of liquid specific gravity. Background technique [0002] In the chemical industry, it is often necessary to accurately measure the specific gravity of the mixed liquid in the reaction tank to determine the reaction conditions. Most of the equipment used in the prior art to accurately measure the specific gravity of liquids is relatively expensive and cannot be displayed in real time, and the operation is relatively cumbersome. [0003] CN105372152 discloses an alcohol specific gravity measuring instrument, which includes a glass hydrometer, a grating ruler sensor and a measurement and control system. However, in this scheme, zero adjustment is required before measurement, and the system efficiency is relatively low. Contents of the invention [0004] An object of the present invention is to so...
