Abstract

The invention discloses a non-equal-diameter ultrasonic flowmeter series verification device and method, belonging to the field of natural gas measurement. The method comprises: connecting a plurality of pipes with non-equal diameters in series through a rectification device, the flow velocity of the fluid changes evenly when passing through the tapered section, rectification occurs when the fluid passes through the rectification section, and flows smoothly into the rear pipe. Install ultrasonic flowmeters with corresponding calibers on each pipeline to obtain measurement data of each ultrasonic flowmeter. The non-equal-diameter ultrasonic flowmeter series verification device and method provided by the present invention enable the fluid to smoothly enter the rear pipe from the front pipe through rectification equipment. Install multiple non-equal-diameter ultrasonic flowmeters on the corresponding pipelines, and the measurement data of multiple non-equal-diameter ultrasonic flowmeters can be obtained at the same time, and the verification of multiple non-equal-diameter ultrasonic flowmeters can be completed without batch measurement. It takes less time and saves labor.

Description

technical field [0001] The invention relates to the field of natural gas metering, in particular to a series verification device and method for non-equal-diameter ultrasonic flowmeters. Background technique [0002] Ultrasonic flowmeter is a velocity flow meter that measures volume flow by detecting the effect of fluid flow on supersonic velocity. Due to its characteristics of almost no interference to fluids, ultrasonic flowmeters are widely used in the measurement of natural gas flow in pipelines. In order to make the measurement results more accurate, it is necessary to verify the ultrasonic flowmeter before measurement. [0003] In the prior art, the verification of the ultrasonic flowmeter is carried out in the following way: clamp the ultrasonic flowmeter of the same caliber on the pipe of the corresponding caliber, and judge whether the measurement result of the ultrasonic flowmeter is accurate or not by comparing the measurement results of different flowmeters , to...
