Side-mounted magnetic float level gauge

Abstract

The invention provides a side-mounted magnetic float level gauge. The side-mounted magnetic float level gauge comprises a main body tube, wherein a connecting flange is arranged on the main body tube;a pneumatic connector is arranged at the upper end of the connecting flange; a display is arranged on the tube wall of the main body tube; an electromagnetic coupling assembly is arranged between thedisplay and the main body tube; the electromagnetic coupling assembly comprises a transducer arranged inside the main body tube; the transducer is used for detecting liquid level change and converting the liquid level change into an electromagnetic signal; a magnetoelectric inductor is arranged inside the display; the magnetoelectric inductor is used for receiving the electromagnetic signal and converting the electromagnetic signal into a display-readable data signal. Through the adoption of the scheme, the side-mounted magnetic float level gauge is more stable to use; in case of factors affecting buoyancy of an ordinary float level gauge, such as an external pressure difference factor and a temperature factor, the side-mounted magnetic float level gauge is more accurate to count.

Description

technical field [0001] The invention relates to the technical field of liquid level detection equipment, in particular to a side-mounted magnetic float liquid level gauge. Background technique [0002] The magnetic float level gauge is used for liquid level detection of liquid media in various pressure-bearing (or open) liquid storage equipment (towers, cylinders, tanks, spherical containers, boilers, etc.) in industrial processes, and can display various liquids on the spot Working conditions and liquid level height, coupled with a liquid level transmitter, the position signal of the liquid level can be transmitted remotely, and the purpose of automatic control and liquid level measurement can be achieved through a certain electrical device. [0003] In order to make the liquid level display more vivid and intuitive, there is also a magnetic flap liquid level gauge, which is developed according to the principle of buoyancy and magnetic coupling. When the liquid level in th...

Problems solved by technology

When the liquid level in the measured container rises and falls, the magnetic float in the body tube of the liquid level gauge also rises and falls, and the permanent magnet in the float is transmitted to the magnetic turning column indicator through magnetic coupling, driving the red and white turning columns to turn over 180° °, when the liquid level rises, the turning column turns from white to red, when the liquid level drops, the turning column turns from red to white, the red and white junction of the indicator is the actual height of the liquid level inside the container, so as to realize the clear liquid level indication, but the float is easily affected by external factors such as air pressure and temperature, which increases the measurement error
