Device for improving installation efficiency of external liquid level meter and application method thereof

Abstract

The invention discloses a device for improving the installation efficiency of an external liquid level meter and an application method thereof. The method comprises the following steps: (1) arranging a mounting plane on the outer side of the bottom wall of a container on which a measuring head is arranged; (2) fixing a measuring head mounting seat on the mounting plane; (3) arranging the measuring head on the measuring head mounting seat on the mounting plane and closely matching the measuring end face of the measuring head with the mounting plane; (4) arranging a self-cleaning device on the inner side of the bottom wall of the container corresponding to the mounting plane and making the self-cleaning device vertical to the inner side of the bottom wall of the container; and (5) arranging a waveguide and keeping the central line of the waveguide concentric with the central line of the measuring head. The device has the advantages of improving vibration signal transmission efficiency between the measuring head and the bottom wall of the container, shorting installation time and improving installation efficiency, automatically cleaning the inner side of the bottom wall of the container opposite to the measuring head and preventing the deposition of deposit from affecting signal transmission and preventing liquid level from fluctuating severely when liquid flows inwards by using the waveguide.

Description

technical field The invention belongs to the field of industrial automation instruments and relates to the application of an external liquid level gauge, in particular to a device for improving the installation quality, efficiency and service life of a measuring head of the external liquid level gauge and an application method thereof. Background technique The installation quality, efficiency and service life of the measuring head of the external liquid level gauge mainly depend on whether the vibration signal received by the measuring head is strong enough. The main factors that affect the strength of the signal received by the measuring head are: 1. The wall of the liquid container where the measuring head is installed is often a curved surface, such as the bottom wall of spherical tanks, horizontal tanks and sausage-shaped vertical tanks, cylindrical vertical tanks and The side walls and the like of the tower-shaped container are all curved surfaces. However, the working...

AI Technical Summary

Problems solved by technology

Although a coupling agent is added between the measuring head and the container wall to exclude air, the loss of the vibration signal passing through this coupling surface is still very large, so that the vibration signal received by the measuring head is greatly weakened

2. If a large amount of liquid enters and exits quickly, it will cause the liquid to flow rapidly in the container

These problems not only seriously affect the long-term stable working effect of the external measuring liquid level gauge, but also greatly increase the difficulty and workload of installation and maintenance, hindering the widespread popularization of the external measuring liquid level gauge
