Ultrasonic wave plays an important role in large flow measurement because of its high reliability and high accuracy. However, in order to give full play to its metrological advantages, the impact of environmental factors on the metrological results must be fully considered in the application process.
1, affected by many external factors, ultrasonic flowmeter in the working process may appear a certain error, if the external interference frequency and its operating frequency is basically the same, then it will reduce the efficiency and accuracy of the transmission, the final measurement of the flow result accuracy is reduced.
2, we must pay attention to the maintenance and testing of ultrasonic flowmeters, detect the fault of the sound channel, and analyze and deal with the abnormal problems. Generally, it is necessary to verify the ultrasonic flowmeter every year, and the verification cycle is up to 2 years, otherwise it cannot be guaranteed that it is in normal working condition.
