Calibrating device for horizontal guide rod magnetic floater liquid level meter

Abstract

The invention relates to a calibrating device for a horizontal guide rod magnetic floater liquid level meter. The calibrating device comprises a precise linear guide rail base, a liquid level meter bracket, a movable module and a laser ranging module, the liquid level meter bracket comprises an upper limiting bracket and a lower limiting bracket; the movable module comprises a reflecting plate and a four-claw floating ball clamp; an upper limiting bracket, a movable module, a lower limiting bracket and a laser ranging module are sequentially mounted on the precise linear guide rail base from left to right; a liquid level meter is horizontally placed on the upper limiting bracket and the lower limiting bracket, a guide rod part of the liquid level meter penetrates through a reflecting plate, and a liquid level floater ball of the liquid level meter is clamped by a four-claw floating ball clamp; the laser ranging module is provided with a laser sensor, and the laser sensor displays the relative displacement distance between the laser ranging module and the movable module in real time and has a zero clearing function. By adopting the horizontal guide rail design, the influence of different media on the result is avoided, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of liquid level gauges, in particular to a verification device for a horizontal guide rod magnetic float liquid level gauge. Background technique [0002] The working principle of the magnetic float level gauge is to use the vertical buoyancy force of the object in the fluid due to the density difference with the surrounding fluid, and make the float ring-shaped and set on a guide rod, and the float moves along the guide rod with the change of liquid level. Do up and down movements. A permanent magnetic object is placed inside the float, and a magnetic sensitive element is installed inside the guide rod. The position of the float is detected by the magnetic sensitive element and converted into a corresponding electrical signal representing the level of the liquid. At present, the verification of magnetic float level gauges mostly adopts vertical containers, and water is added to change the liquid level posi...
