A float suitable for the interface of two immiscible liquids

Abstract

The invention discloses a floater applicable to an interface of two types of immiscible liquid, and provides a design for a floater which is a novel liquid level meter. The floater comprises a floater body (1). The floater body comprises a vertically upward 'cup-shaped' open space and a vertically downward 'cup-shaped open space, a liquid cavity (2a) is formed in the vertically upward open space, a liquid cavity (1a) is formed in the vertically downward open space, and the specific gravity of the integral floater body ranges between the specific gravity of the upper liquid and the specific gravity of the lower liquid. The floater which is the novel liquid level meter has the advantages that owing to the structural design, change of the position of the floater due to change of densities of the liquid can be spontaneously corrected; the bottoms of the 'cup-shaped' spaces of the floater which is the novel liquid level meter and the interface of the liquid can be assuredly positioned at the same horizontal altitude, so that the floater brings convenience for sensor placement, measurement and computation.

Description

technical field [0001] The patent of the invention belongs to a liquid level measuring instrument, and in particular relates to a structure design of a float for measuring the height of a liquid layer, which is suitable for monitoring the interface between two immiscible liquids. Background technique [0002] In the fields of oil depot management, petrochemical industry, pharmaceutical manufacturing, and waterworks, sewage treatment plants, etc., two immiscible liquids often coexist in one system. The interface between the two liquids is an important measurement and Control technical parameters. At present, the commonly used liquid level sensor counterweights the float according to the different densities of two specific liquids, so that the density of the float is between the densities of the two liquids, so that the float can be suspended on the interface of the two liquids. However, due to the fixed weight of this float, when the density of one or both of the two liquids...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the following problems in the traditional liquid level float: (1) when the density of one or two liquids changes in the traditional liquid level float in the immiscible liquids of different densities, the relative The position will change and cause errors; (2) Due to the space size of the float itself, the traditional liquid level gauge float cannot intuitively and accurately give the specific position of the liquid interface, which brings certain difficulties to the measurement and sensor placement
