Embodiment
[0022] Such as Figure 1-3 , this embodiment is specifically a mobile intelligent multi-protocol flowmeter calibration device, including a flowmeter valve body 1, a flowmeter 2, and the flowmeter 2 is fixedly installed on the top of the flowmeter valve body 1. It is characterized in that the flowmeter A calibration device 3 is installed on the side of the valve body 1. The calibration device 3 includes a stainless steel straight pipe section 4. The upper end of the stainless steel straight pipe section 4 moves through a flow control rod 5. The stainless steel straight pipe section 4 is provided with a rubber gasket at the point where the flow control rod 5 penetrates. The flow control rod 5 passes through the first bevel gear 6 through threads, and the first bevel gear 6 is connected with the stainless steel straight pipe section 4 through a bearing. The first bevel gear 6 is connected with an adjustment ring 8 through the second bevel gear 7, and the adjustment ring 8 is along...

Description
technical field [0001] The invention relates to the technical field of flowmeters, in particular to a mobile intelligent multi-protocol flowmeter calibration device. Background technique [0002] The English name of the flowmeter is flowmeter, which is defined by the National Committee for Scientific and Technical Terms as: an instrument that indicates the measured flow rate and (or) the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow of fluid in pipelines or open channels. [0003] Flowmeters are further divided into differential pressure flowmeters, rotameters, throttling flowmeters, slit flowmeters, volumetric flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc. Classified by medium: liquid flowmeter and gas flowmeter. When the flowmeter is used, the flowmeter will be calibrated, and the flow of different sizes needs to be calibrated during the calibration process. When the existing calibrati...
