Document Type and Number:
WIPO Patent Application WO/2017/084466
Kind Code:
A8
Abstract:
Disclosed is a ball float type liquidometer with vernier display, comprising a ball float chamber (2) and a ferromagnetic spherical ball float (1) provided therein, a vernier (8) outside the ball float chamber (2), a calibrated scale (6) and a vernier guide rail (3, 3'), wherein the vernier (8) comprises a magnetic steel member (8-2), a frame (8-5) and a rolling system which is horizontally fixed and sheathed in the frame (8-5); the rolling system comprises rolling wheels (8-4, 8-4') provided with radial grooves along a circumferential surface, rolling bearings (8-1, 8-1') and shafts (8-3, 8-3'); the magnetic steel member (8-2) is located between the ball float chamber (2) and the frame (8-5) and is fixed outside one side face close to the ball float chamber (2) on the frame (8-5), and a magnetic pole of the magnetic steel member (8-2) is directly oriented towards the ball float (1); the vernier guide rail (3, 3') is sheathed in the rectangular frame (8-5) and is located between the magnetic steel member (8-2) and the rolling system; and the rolling system enables the rolling wheels (8-4, 8-4') to roll vertically along the vernier guide rail (3, 3') at groove positions of the rolling wheels through a magnetic coupling force between the magnetic steel member (8-2) and the ball float (1). The liquidometer is simple and scientific in structure, reliable in application performance, easy to manufacture and low in cost.
