Introduction to the Measurement Principle of Handheld Ultrasonic Flow Meter

Abstract: The introduction information of the measurement principle of the hand-held ultrasonic flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. 1. In industrial and mining where the measurement pipeline is relatively old, try not to use 2 acoustic layers (V method) to install the sensor, and 1 acoustic layer (Z method) should be used first. , it is easy to be measured against the flow. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is an introduction to the measurement principle of the hand-held ultrasonic flowmeter. 1. In industrial and mining where the measurement pipeline is relatively old, try not to use 2 acoustic layers (V method) to install the sensor, and 1 acoustic layer (Z method) should be used first. , it is easy to be received by the flow sensor under test, and the signal strength of the flowmeter host is guaranteed, and the high-precision measurement value can be guaranteed. 2. When measuring new pipelines, when encountering paint or zinc-crossing pipelines, the surface of the pipeline can be treated with roving first, and then continue to be treated with spun yarn, so as to ensure that the installation point of the flow sensor of the ultrasonic flowmeter is smooth and flat. The flow probe of the flowmeter can be in good contact with the outer wall of the measured pipe. 3. When the pipeline is vertically upward, if the fluid in the pipeline flows from bottom to top, it can be measured. If the liquid flows from top to bottom, this pipeline is not suitable for flow data collection. 4. In addition, before collecting flow data for a pipeline, be sure to measure the outer circumference of the pipeline (with a tape measure), wall thickness (with a thickness gauge), and the temperature of the outer wall of the pipeline (surface temperature measuring instrument), etc., because many When the measurement accuracy is not accurate, it is not because of the problem of the instrument itself, but the so-called parameter deviation problem of the measurement site staff. You must trust your eyes, not your ears. 5, to choose the appropriate ultrasonic flowmeter. There are many types of ultrasonic flow meters. How to choose an ultrasonic flowmeter? Many people who call Shanghai Senyi Intelligent Instrument Technology Department will say:“Communicate with your company, let me learn a lot, thank you!”This is because the technicians of Shanghai Senyi Intelligent Instrument adhere to the result of the concept of Senyi! The technicians of Shanghai Senyi Intelligent Instrument will not think to sell their products, but recommend products according to the user's working conditions and practical applications, and recommend the ultrasonic flowmeter suitable for users. Many times, this flowmeter is sold in Shanghai Senyi. Smart instruments are not for sale. So the people who hit it will be emotional and grateful. In terms of choosing a hand-held ultrasonic flowmeter, I don’t want to say more, or choose according to the actual situation of each working condition. If there are working conditions, interested friends can also communicate with the electric technology. 6. When operating the handheld ultrasonic flowmeter, it must be operated in accordance with the requirements of the flowmeter manufacturer. don't want“I thought it could be done like this”In fact, many irregular operations are based on sacrificing the accuracy of ultrasonic flowmeters. Such as: coating the coupling agent, the Z method installation must pass the center line, etc. 7. For the measurement of relatively special media, such as natural gas, compressed air, etc., it is necessary to choose carefully. If the gas pressure in the aisle is less than 8KG, you should not use an ultrasonic flowmeter as a measurement basis, but a mechanical instrument for measurement. 8. For the working condition of pulse flow, it is necessary to choose a suitable ultrasonic flowmeter, and the sampling time interval of ultrasonic wave should be selected, which is less than the ultrasonic flowmeter of the pulse frequency interval, otherwise the actual flow rate of the fluid has changed, and your ultrasonic flowmeter has not yet been installed. It is manifested that the error caused by this is very large. 9. Regarding some conventional installation precautions and the selection of installation points, I will not describe them here. I believe that practitioners who have been exposed to ultrasonic flowmeters should be very clear. If they are not clear, they can call Shanghai Senyi Intelligent Instrument for exchange and consultation ! The above is the whole content of this article.
