Float gauge with vernier or buoy display

Abstract

The invention relates to a float-type liquidometer with a vernier or a float for displaying. The float-type liquidometer comprises a float chamber made of nonferromagnetic material, a ball float made of ferromagnetic material and the vernier outside the float chamber. The vernier comprises a magnetic steel and a linear bearing. The magnetic steel is fixed on the linear bearing penetrating a linear guide rail. The other kind vernier comprises a magnetic steel, more than three universal bearings and a plate. The three universal bearings are fixed on the plate in the triangle form. The vernier moves vertically through magnetic bonding force of the magnetic steel and the float. By employing a fixed pulley, a counter weight and a connecting rope, or fixing a buoy on the vernier, the float is lifted upward under the buoyancy of liquid in a vernier chamber. Teletransmission is realized by measuring resistance value of a loop twisted with a resistance wire. By the use of the float-type liquidometer, the problems of on-site indication difficulty and liquid level measurement difficulty of many places are solved. The float-type liquidometer is sensitive, reliable, simple in structure, easy to produce, assemble, adjust and mount, low in cost, marked and visual in displaying and wide in range of application.

Description

technical field

[0001] The invention relates to the field of liquid level measurement, in particular to a float type liquid level gauge displayed by a vernier or a buoy. Background technique

[0002] Existing on-site indicating liquid level gauges include glass plate type, magnetic flap (column) type, buoy type, two-color water level gauge, etc. The glass plate type can only be visually inspected at close range, and it is difficult to visually inspect after being covered with dust or medium pollution, and the pressure resistance is limited. The structure of the magnetic flap (column) is relatively complex and prone to garbled characters, and the operating temperature is limited. The applicable medium range of the two-color water level gauge is narrow and the pressure resistance is also limited. In addition, the glass plate type liquid level gauge, the magnetic flap (column) type and the two-color water level gauge cannot adopt overall insulation, resulting in high energy c...
