Solid-state coupling patch for measurement of ultrasonic flowmeter and preparation method of solid-state coupling patch

Abstract

The invention provides a solid-state coupling patch which is reasonable in structural design and used for measurement of an ultrasonic flowmeter and a preparation method of the solid-state coupling patch. The measurement process of the ultrasonic flowmeter becomes convenient, fast, sanitary and safe. The solid-state coupling patch is prepared from the following components in percentage by mass: 20-40% of water-soluble polymer gel, 15-30% of an adhesive, 35-40% of glycerol and the balance of deionized water. The preparation method comprises the following steps of firstly, adjusting the temperature of the deionized water to 25-35 DEG C, then adding the water-soluble polymer gel into the deionized water, and performing stirring for 20-30 minutes until the water-soluble polymer gel is completely dissolved to obtain a mixture a; slowly dissolving the adhesive in a glycerol solution, and performing stirring for 20-30 minutes until the adhesive is completely dissolved to obtain a mixture b; slowly adding the mixture b into the mixture a, and performing stirring for 30-40 minutes until the mixture b is uniformly distributed; and injecting a mixture into a curing container for curing.

Description

technical field [0001] The invention relates to a solid-state coupling patch for ultrasonic flow meter measurement and a preparation method thereof. Background technique [0002] As a non-contact measuring instrument, ultrasonic flowmeter is almost not affected by medium parameters, and has reliable measurement accuracy. It has been widely used in electric power, chemical industry, metallurgy and other industries. At present, the coupling agent for ultrasonic flowmeter probes is grease or butter, etc. When using, first clean the outer surface of the pipe, apply a layer of grease or butter to the probe and fix it on the surface of the pipe to prevent air between the probe and the pipe from making the measurement The result is inaccurate. During the operation of the measuring personnel, due to the uneven application of the couplant, the air between the probe and the pipe is not completely discharged, which affects the measurement results. At the same time, it is easy to cause...

AI Technical Summary

Problems solved by technology

During the operation of the measuring personnel, due to the uneven application of the couplant, the air between the probe and the pipe is not completely discharged, which affects the measurement results. At the same time, it is easy to produce collision scratches on the surface of the probe, which affects the measurement accuracy and is not conducive to the service life of the probe.

After the measurement, remove the grease or butter with a rag or toilet paper, and sometimes the grease and butter on the pipeline have not been treated, which is very inconvenient and hygienic to operate in thermal power generation enterprises, chemical and metallurgical industries, and other test sites, and it is difficult to completely wipe them off. In addition, the oil couplant left on the high-temperature pipeline pollutes the environment and is easy to cause fire.
