The invention discloses an on-line pressure comparison detection device, which comprises a standard meter used to connect with a comparison pipeline, a first connection end used to connect with a field meter, and a connection between the first connection end and the standard meter. A comparator that is connected to each other and is used to receive and compare field measured values with standard measured values. The pipeline where the field meter is located is equipped with a parallel comparison pipeline, and the standard meter is connected to the comparison pipeline. According to the principle of the connector, the standard measurement value measured by the standard meter should be equal to the field measurement value of the field meter . The comparison device is connected to the field meter through the first connection port, and receives and compares the field measurement value and the standard measurement value, and can judge whether the field meter is accurate through the comparison result, so it can be compared without removing the field meter If the field meter is inaccurate, it can be directly corrected. This ensures that the field meter can provide accurate field measurement values for the 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...
