The invention discloses an on-line pressure comparison detection device. The on-line pressure comparison detection device comprises a standard meter, a first connection end and a comparison device, wherein the standard meter is used for connecting a comparison pipeline, the first connection end is used for connecting a site meter, the comparison device is connected with the first connection end and the standard meter and is used for receiving a site measurement numerical value and comparing the site measurement numerical value with a standard measurement numerical value, a parallel comparison pipeline is arranged at a pipeline where the site meter is located, the standard meter is connected with the comparison pipeline, the standard measurement numerical value measured by the standard meter shall be equal to the site measurement numerical value of the site meter according to a communicator principle, the comparison device is connected with the site meter by the first connection end and is used for receiving and comparing the site measurement numerical value with the standard measurement numerical value, whether the site meter is accurate or not can be judged according to the comparison result, thus, comparison detection can be performed without disassembling the site meter, the site meter can be directly corrected if the site meter is not accurate, and the site meter can be enabled to provide the accurate site measurement numerical value for a control system.
Description
technical field [0001] The invention relates to the technical field of meter detection, in particular to an online pressure comparison detection device. Background technique [0002] Electric power, petroleum, chemical and other industries will use a large number of pressure gauges to measure production parameters in real time, and control and adjust each control valve according to the measurement results. Therefore, the accuracy of the gauges directly affects the normal production of the enterprise. [0003] In the prior art, once the meter breaks down or the measurement is inaccurate, the usual treatment method is to remove the meter and bring it back to the laboratory for calibration. However, some meters cannot be dismantled during the normal production process, and running with faults will bring great safety hazards to production. [0004] Therefore, how to provide an online pressure comparison detection device is a technical problem that those skilled in the art urgen...
