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

Embodiment Construction

[0011] The present invention is described in further detail below in conjunction with accompanying drawing:

[0012] see figure 1 1. At the position where the measuring head is installed outside the bottom wall of the container, the surface of the convex container bottom wall larger than the outer diameter of the measuring head is processed into a mounting plane (3) for installing the measuring head, for example, processed into the installation plane. In this way, the entire end surface of the measuring head is in good contact with the container wall, which greatly improves the efficiency of the vibration signal passing through the coupling surface between the measuring head and the container wall. In order to ensure a high coupling coefficient between the measuring head and the bottom wall of the container, the surface flatness of the measuring head installation plane (3) should be less than 0.1 mm, for example, less than or equal to 0.05 mm. Surface roughness should be gr...

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) arranginga 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 [0001] 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 [0002] 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. Howe...
