Description

Technical Field

[0001] The present application relates to the technical field of electromagnetic flowmeter calibration, and in particular to an electromagnetic flowmeter calibration device. Background Art

[0002] The electromagnetic flowmeter is a new type of flow measurement instrument that developed rapidly in the 1950s and 1960s with the development of electronic technology. The electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the induced electromotive force when the conductive fluid passes through an external magnetic field. At present, many related transactions involving materials of chemical companies are mainly transported through pipelines and measured by electromagnetic flowmeters. In order to promote fair and just trade, it is necessary to ensure the accuracy of the measurement value of the electromagnetic flowmeter. Therefore, the electromagnetic flowmeter needs to be calibrated regularly.

[0003] After checking the announcement number: CN217687421U, a calibration device for an electromagnetic flowmeter is disclosed. This technology discloses "including: a metering tank, a metering piece, a first main pipeline, a first valve and an electromagnetic flowmeter to be tested; the metering tank and the metering piece are detachably connected, the metering tank is used to store liquid medium, and the metering piece is used to measure the volume of the liquid medium in the metering tank; the lower end of the metering tank is connected to the first main pipeline; the first main pipeline is connected to the first valve and the electromagnetic flowmeter to be tested, etc., which has the technical effects of reducing the number of times the electromagnetic flowmeter is sent out for calibration, reducing the impact on the production of the enterprise due to the long time of sending out for calibration, and improving the production and operation efficiency of the enterprise".

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing electromagnetic flowmeter calibration device does not have a moving mechanism. Since the electromagnetic flowmeter needs to be placed between two detection tubes when testing the electromagnetic flowmeter, the detection tubes in the existing calibration device are generally fixed, which makes it troublesome to place the electromagnetic flowmeter to be tested. The lack of a moving mechanism makes it inconvenient to adjust the position of the detection tube, which reduces the practicality of the calibration device. Secondly, the existing electromagnetic flowmeter calibration device does not have a placement component. When testing the electromagnetic flowmeter, the tester generally holds the electromagnetic flowmeter to be tested. The hand-held method easily causes the electromagnetic flowmeter to move during calibration, making the calibrated data inaccurate. The lack of a placement component makes it inconvenient to stably place the electromagnetic flowmeter during calibration, which reduces the accuracy of the detection results of the calibration device. Utility Model Content
