The invention discloses a mobile flow online calibration system. The system comprises a data acquisition, compensation and diagnosis controller, a base, a high-precision Coriolis mass flowmeter, a connecting pipeline, a temperature transmitter and a pressure transmitter, the data acquisition, compensation and diagnosis controller is used for acquiring the operation temperature of the system in real time and compensating the influence of the operation temperature on the zero point of the mass flow meter; and the data acquisition, compensation and diagnosis controller diagnoses the Coriolis mass flow meter on line in real time, and ensures that the data measured by the standard meter for the flow online calibration system is accurate by diagnosing and analyzing the reliability of the measured data. The data acquisition, compensation and diagnosis controller is used for acquiring system operation pressure in real time and compensating the influence of the operation pressure on the measurement of the mass flow meter; the system provided by the invention is suitable for on-line calibration of field work flowmeters operated under different temperature and pressure conditions.
Description
technical field [0001] The invention relates to a mobile flow on-line calibration system, which belongs to the technical field of fluid detection. Background technique [0002] In the field of industrial fluid measurement, regular calibration of the working flowmeter in use is a very important part of the flowmeter maintenance work, which can ensure the measurement accuracy and performance of the flowmeter. Connect the working flowmeter to the standard device, and compare the fluid flowing through the working flowmeter with the standard device through weighing or the measurement data of the standard meter by means of circulation, so as to achieve the purpose of calibrating the working flowmeter and make the working flowmeter Operates within rated accuracy. [0003] Using the standard meter method to calibrate the working flowmeter is a convenient method. The standard meter can be integrated into a mobile standard device to realize online calibration of the working flowmeter...
