Embodiment 1

[0042] The first embodiment provides an automatic calibration device for standard metal gauges,

[0043] Such as figure 1 As shown, the device includes: a housing 1, a first water tank 2, a second water tank 3, a standard metal gauge 4, a metal gauge 5 to be calibrated, a monitoring mechanism 6 and a calibration control system;

[0044] The first water tank 2 is arranged at the bottom of the housing 1, the second water tank 3 is arranged at the top of the housing 1, and a water pump 7 is arranged between the first water tank 2 and the second water tank 3;

[0045] The standard metal gauge 4 is arranged on the support of the housing 1, the standard metal gauge 4 is connected to the second water tank 3, and the metal gauge 4 to be calibrated is arranged on the standard metal gauge 3 below;

[0046] The monitoring mechanism 6 includes a first industrial camera 61 and a second industrial camera 62, and the first industrial camera 61 is arranged on the bottleneck side of the stan...

Embodiment 2

[0080] The second embodiment provides a method for automatic calibration of a standard metal gauge, comprising the following steps:

[0081] S1: Send water to the first water tank, and send the water in the first water tank to the second water tank by controlling the water pump.

[0082] Specifically, the S1 step also includes:

[0083] S101. Observing through the second visible liquid level, when the second water tank is insufficient, supplying water through the water pump;

[0084] S102. Constantly temperature the water in the first water tank and the second water tank for a period of time, and record the water temperature in the corresponding water tank through the first thermometer and the second thermometer;

[0085] S103. When the temperature of the second water tank is too high, control the temperature through the temperature controller.

[0086] Further, the water temperature of the first water tank and the second water tank is controlled at 20°C, with an allowable e...

Abstract

The invention relates to an automatic calibration device and method for a standard metal meter. The device comprises a shell, a first water tank, a second water tank, a standard metal meter, a to-be-calibrated metal meter, a monitoring mechanism and a calibration control system; the monitoring mechanism comprises a first industrial camera and a second industrial camera, the first industrial camerais arranged on the side edge of the bottleneck of the standard metal meter and is used for reading scales of the standard metal meter, and the second industrial camera is arranged on the side edge ofthe bottleneck of the to-be-calibrated metal meter and is used for reading the scales of the to-be-calibrated metal meter; the calibration control system comprises a central processing unit, a firstdata acquisition unit, a second data acquisition unit and a water pump control unit, the first data acquisition unit is electrically connected with the first industrial camera, the second data acquisition unit is electrically connected with the second industrial camera, and the water pump control unit is electrically connected with a water pump. According to the device and the method in the invention, the scales can be automatically read, the calibration process can be automatically controlled, the interference of human factors is avoided, the time is saved, and the calibration efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to an automatic calibration device and method for a standard metal gauge. Background technique [0002] As a standard measuring instrument for measuring the volume of liquids and gases, standard metal gauges are widely used in petrochemical, oil depots, gas station oil measurement and various aspects of enterprise production. Standard metal gauges are divided into three categories: first-class standard metal gauges, second-class standard metal gauges and third-class standard metal gauges (working gauges). Body, cylinder, lower cone, valve, etc., with a volume ranging from 1L to 5000L, of which 20L third-class metal measuring instruments are widely used, including JJB-320L, BL-320L, BJL-20L and other models Specifications (JJB-320L and BL-320L have no water outlet at the bottom), and are often used for self-calibration in the fuel dispenser cycle, production medium ratio and oth...
