Abstract

The invention discloses an automatic calibrating device for a glass floating meter. The automatic calibrating device comprises a transparent stable liquid barrel, a weighing mechanism, a moving mechanism and an image sensor, the stabilizing liquid barrel is of a liftable structure, a bracket and a supporting column are arranged in the stabilizing liquid barrel, a standard ball is arranged in the bracket, and the supporting column penetrates through the bracket and can support the standard ball; the weighing mechanism is arranged above the stabilizing liquid barrel and is used for measuring the weight of an object hung on the stabilizing liquid barrel; the moving mechanism is used for hanging the glass floating meter on the weighing mechanism and taking down the glass floating meter from the weighing mechanism; a shooting area of the image sensor is aligned with a detected scale line of the glass floating meter in the stable liquid barrel; the glass floating meter automatic calibrating device is used for regulating and controlling the lifting height of the stable liquid barrel according to the detection result of the image sensor so as to complete the calibration of the glass floating meter; according to the scheme, automatic hanging, taking down and verification of the glass floating meter are achieved, so that manual operation is omitted, verification efficiency is greatly improved, and the problem that the automation degree is too low in the verification process of an existing glass floating meter is practically solved.

Description

technical field [0001] The invention relates to the technical field of instrument verification devices, in particular to an automatic verification device for glass float gauges. Background technique [0002] Glass float meter has a wide range, including petroleum density meter, alcohol meter, sugar meter, seawater density meter, milk meter and so on. The verification of glass float meter is based on JJG42-2011 "Verification Regulations for Working Glass Buoymeter". The disadvantages of this verification method are: [0003] (1) For the measured density less than 650kg / m 3 The glass buoymeter has not yet found a test solution with a stable density. Therefore, this regulation does not apply to less than 600kg / m 3 to 650kg / m 3 Verification of low-density range petroleum density meters; [0004] (2) The test solution is highly corrosive and toxic, threatening the health of test personnel; [0005] (3) The preparation process of the test solution is cumbersome, the stirrin...
