Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeters, and more particularly to a packaging tool for an ultrasonic flowmeter probe. Background Art

[0002] Natural gas fluids are transported to various locations via pipelines. Accurately knowing the amount of fluid flowing through the pipeline is crucial, especially when the fluid is being traded or sealed. However, even in situations where sealed transport is not occurring, measurement accuracy is still required, and in these cases, ultrasonic flow meters are used.

[0003] An ultrasonic flowmeter can be used to measure the volume of fluid flowing in a pipeline. Ultrasonic flowmeters offer sufficient accuracy for sealed conveying. In an ultrasonic flowmeter, an acoustic signal is sent back and forth through the fluid flow being measured. The flow rate of the fluid in the flowmeter is determined based on the parameters of the received acoustic signal. The volume of the fluid flowing through the flowmeter can be determined based on the calculated flow rate and the known cross-sectional area of the flowmeter.

[0004] Ultrasonic flowmeter mainly consists of an ultrasonic transducer (or an ultrasonic flow sensor consisting of a transducer and a measuring tube) and a converter installed on the measuring pipe;

[0005] When the probe on the existing ultrasonic transducer is in use, the package will directly seal the probe. In this way, if the pressure inside the meter is 200kPa and the atmospheric pressure is 100kPa, the pressure difference of the probe inside the package will be 100kPa, which will not only affect the measurement results, but also affect the service life of the probe.

[0006] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
