Abstract

The invention provides a wireless data transfer online liquid level meter, which comprises a case, and a hardware circuit positioned in the case, wherein the hardware circuit comprises a strain sensor and a wireless data transfer module connected with the strain sensor; a lifting hook which extends out of the case is arranged on a strain beam of the strain sensor; and the strain sensor measures the tension of a suspended object on the lifting hook and transmits the tension through the wireless data transfer module. By the wireless data transfer online liquid level meter, the measuring method and precision are greatly improved, the wireless data transfer online liquid level meter can be applied to a plurality of scientific fields, and because the measuring principle is definite, and the precision is greatly improved, the liquid level meter can serve as a measurement standard under certain conditions; and in addition, because wireless data transfer can be realized, the monitoring automation is greatly improved, the production cost is greatly reduced, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a liquid level gauge, in particular to an online precision liquid level gauge. Background technique [0002] Solution level is an important measured parameter in petrochemical, electric power, food and other industrial production. Due to the error and failure of liquid level measurement, the control system will malfunction, the production line will fail, the boiler will explode, and the liquid in the container will run, leak, and leak, which will cause vicious accidents, cause economic losses and endanger personal safety. There are many types of existing liquid level measurement methods and instruments, but they all have obvious defects. For example: 1. The pressure transmitter measures the liquid level. The pressure pipe is easy to block and freeze, and the lower part of the tank needs to be opened, which is difficult to solve the problem of corrosion resistance and explosion protection. 2. The accuracy of liquid level measur...
