What are the advantages and disadvantages of ultrasonic flow meter scales

Abstract: what are the advantages and disadvantages of ultrasonic flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Ultrasonic flowmeter with high accuracy, without resistance measurements, and the advantages of lower total cost of ownership, are rapidly developed into the flow measurement field, especially the measurement of choice for hydrocarbons, and gained popularity in the field of oil and gas. Ultrasound. More flow meter manufacturers choose model price quote you are welcome to inquire, here is what are the advantages and disadvantages of ultrasonic flow meter scale article details. Ultrasonic flowmeter with high accuracy, without resistance measurements, and the advantages of lower total cost of ownership, are rapidly developed into the flow measurement field, especially the measurement of choice for hydrocarbons, and gained popularity in the field of oil and gas. Ultrasonic flowmeter is a kind of flow meter use is very convenient, especially in large diameter pipeline, portable ultrasonic flowmeter sensor can be installed outside the pipe surface,, does not destroy the original line measuring the implementation does not block the traffic, so was welcomed by the masses of users. 1 of working principle of ultrasonic flowmeter and the ultrasonic transmission is in the flow of fluid velocity of flow in the load information, so by the received ultrasound can detect the flow velocity of the fluid, thereby converted to flow. According to the test, can be divided into velocity difference method ( The time difference method, phase and frequency difference method) , doppler method, beam deflection method, noise and the relevant laws such as different types of ultrasonic flowmeter. Zui often measurement methods at present basically has two kinds: the time difference method and doppler method. Ultrasonic flowmeter by the ultrasonic transducer, electronic circuit and flow display and cumulative system of three parts. Ultrasonic transmitting transducer converts electrical energy into ultrasonic energy, and launch it to the flow in the body, the receiver, the received ultrasonic signal amplified by electronic circuit and converted to represent the flow of electrical signals, display and integrating instrument for supply and integrating, thus to realize the flow detection and display. 2 advantages ( 1) Outer clamp type ultrasonic flowmeter can realize non-contact measuring flow, even within the plug-in or stick type ultrasonic flowmeter, the pressure loss is almost zero, the flow measurement is zui better convenience and economy. （ 2) Ultrasonic flowmeter oil, gas and water of various media can be measured, its application field is very broad. （ 3) Manufacturing cost almost nothing to do with caliber ultrasonic flowmeter, in big runoff measurement occasions has a reasonable price, easy installation and use of comprehensive competitive advantage. （ 4) Portable ultrasonic flowmeter can realize a flowmeter in the pipe of various calibers, all kinds of material flow, as a standard table online calibration, the comparison or during verification of the preferred type of flow meter. （ 5) Ultrasonic flowmeter with its measurement principle is based on the length and the time of two basic physical quantity traceability convenience, it will surpass other foreseeable principle of flowmeter, became the basis for the flow standard even flow of carrier. （ 6) Ultrasonic flowmeter operation energy consumption is very small, can easily realize the long battery power supply, combined with advanced intelligent host can easily for wireless communication network, its more wide application prospect. 3 disadvantages ( 1) Ultrasonic flowmeter faults mainly existed in the current body temperature range of the ultrasonic transducer and the coupling between transducer and the pipe materials heat resistance level of restrictions, and is under the high temperature flow body sound transmission speed of the original data is not complete. At present our country can only be used to measure the fluid under 200 ℃. （ 2) Anti-interference ability is poor, vulnerable to bubbles, scaling, pump, such as the influence of ultrasonic noise, deterioration in accuracy. If has the above situation, the accuracy of light, or instrument does not display. （ 3) In addition, ultrasonic flowmeter measurement line is more complicated than the general flow meter. This is because, in general industrial measurement of liquid flow velocity is often a few meters per second, and propagation velocity of sound waves in a fluid is about 1500 m/s, by flow velocity ( Traffic) Zui large amount of changes to the change of the velocity of sound is also 10 - 3 orders of magnitude. If you want the accuracy of measuring the velocity of & plusmn; 1%, the measuring accuracy of the sound velocity for 10 - 5 ~ 10 - 6 orders of magnitude, so must have perfect measuring circuit to realize, that is ultrasonic flowmeter is only under the former title of integrated circuit technology rapid development can be the cause of the practical application. （ 4) Installation is not intellectual, incorrect installation, can affect the accuracy of measurement. （ 5) Short service life, general accuracy can only guarantee two years. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

With technology speeding up in lighting speed, have created quite a name for itself amidst tuning fork liquid density meter and it happens to have a lot of benefits as well.
