It solves the technical problems of time-consuming and labor-intensive verification of liquid level gauges and low precision existing in the prior art. It includes a tubular conduit assembly with a liquid inlet pipe at the bottom, a support plate at the bottom of the conduit assembly, and a pressure-type liquid level transmitter on the support plate that can measure the pressure of the liquid in the conduit assembly. A laser range finder mounting bracket is provided on the top of the tube assembly, a hollow float assembly is arranged inside the conduit assembly, and a laser range finder is provided on the laser range finder mounting bracket. The invention has the advantages of high liquid level detection reliability, high detection precision, and the ability to detect liquid density and inclination angle.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a portable multifunctional liquid level measuring device based on laser and pressure, a liquid density measuring method and an inclination angle measuring method. Background technique [0002] Liquid level gauges are instruments used to indicate and control liquid levels in industrial process measurement and control systems. At present, in the measurement of liquid level in industrial applications, almost all liquid level gauges are used. Its accuracy is directly related to the interests of the country and enterprises, so the requirements for the accuracy of liquid level gauges are increasing day by day. However, the current verification methods for liquid level gauges are rarely able to accurately verify and calibrate liquid level gauges, except for sending them to relevant metrology institutes for verification and manual measurement. The above two methods...
