In fact, there is no ranking, many manufacturers of ultrasonic flowmeters are not among them, it can be seen that many sales-oriented companies have become production-oriented, so the rankings are some means of some network companies.

Ultrasonic flowmeter and electromagnetic flowmeter are the same, because the instrument flow channel is not provided with any obstruction parts, are unobstructed flowmeter, is suitable for solving the difficult problem of flow measurement of a kind of flowmeter, especially in the large-diameter flow measurement has more prominent advantages, it is one of the rapid development of a class of flowmeter.

Ultrasonic flow meter

An ultrasonic flow meter is an instrument that measures flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). According to the way of detection, ultrasonic flowmeter can be divided into propagation velocity difference method, beam offset method, etc., its advantage is that the measurement is more convenient, economical and accurate, and is widely used in petroleum, chemical industry, metallurgy and other fields.

Ultrasonic differential plexus signal flowmeter is a kind of non-contact flowmeter, which has the advantages of high precision, strong reliability and long service life, so it has been widely used in industrial production. The following is the ranking of imported ultrasonic flowmeters:

1.The Prosonic Flow series of ultrasonic flowmeters from Endress+Hauser in Germany are suitable for flow measurement of various industrial fluids due to their high precision, high reliability, and easy installation and maintenance.

2.The Micro Motion series ultrasonic flowmeter of Emerson Company in the United States adopts advanced digital signal processing technology and multi-beam measurement technology, which has the characteristics of high precision, high stability and strong anti-interference ability.

5.The Sitrans F series ultrasonic flowmeter of Siemens Company of the United States adopts advanced digital signal processing technology and multi-beam measurement technology, which has the characteristics of high precision, high stability and strong anti-interference ability.

In short, imported ultrasonic flowmeter has the advantages of high precision, high reliability, easy installation and maintenance, etc., and is an indispensable and important equipment in industrial production.

First of all, the installation mode of these two flowmeters is different, most of the electromagnetic flowmeters are pipe section type installation and a small part of the plug-in type, these two installation methods need to cut and dig holes on the pipeline, and the whole pipeline needs to be intercepted and stopped, in order to install;

The ultrasonic flowmeter can be installed in three ways: clamp-on, plug-in and pipe section, and the commonly used ones are clamp-on and plug-in, which are installed without stoppage. Among them, the external clamp installation will not damage the pipeline, will not contact with the tested fluid, and there is no possibility of any leakage.

Then, the versatility of these two flowmeters for pipe diameter is very different, electromagnetic flowmeters are used for one pipe diameter, and even the corresponding flowmeter lining of different pipeline fluids is also different, and cannot be used on other pipelines;

The external clamp type and plug-in type of ultrasonic flowmeter do not have this trouble, and can be used in different materials, different sizes, and different pipelines of the tested fluid.

Moreover, the way these two flowmeters measure the pipeline fluid is different, the electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction, and measures the flow rate of the conductive fluid according to the electromotive force induced by the conductive fluid through the applied magnetic field, and all the data that cause it to only measure the conductive body;

The ultrasonic flowmeter uses the time difference method to measure, and the fluid flow is calculated by the time difference between the signal sent by the upstream sensor and the signal sent by the downstream sensor, so the ultrasonic flowmeter can measure almost all fluids except for the fluid with more solid content or many bubbles.

ps.The above measurements are all in the state of full pipe, and both the electromagnetic flowmeter and the ultrasonic flowmeter can only measure the flow rate in the state of full pipe.

The communication protocols of these two flowmeters are relatively rich, almost all of them are equipped with 4-20mA and RS485 as standard, and even other communication protocols on the market can be selected, which is an advantage over other flowmeters. Xunsheng ultrasonic flowmeter is not only equipped with 4-20mA and RS485 as standard, but also has OCT alarm settings (the upper and lower limits can be set, and an alarm signal will be sent when reached), and also supports optional communication protocols such as BACnet and LoRa.

The state stipulates that the verification cycle of ultrasonic flowmeters is once every three years, while the verification cycle of electromagnetic flowmeters is once every two years.

The electromagnetic flowmeter needs to check whether the external equipment is flooded with water or other substances, whether there is an electromagnetic field device or wires across the meter, which will have an impact on the measurement of the electromagnetic flowmeter.

The ultrasonic flowmeter will be much more convenient, maintenance only need to check the flowmeter display of the sq value, sound velocity ratio and other parameters are good, if there is a problem with the value, you can check whether the sensor position is foreign or loose, and the clamp type and plug-in type can be tested and maintained under pressure.

Ultrasonic flowmeter is a commonly used flow measurement instrument, which uses ultrasonic technology for flow measurement, which has the advantages of wide measurement range, high precision, and not easy to be affected by medium. However, there are also some disadvantages of ultrasonic flowmeters, which mainly include the following aspects:

1.Higher: Ultrasonic flowmeters are more expensive to manufacture and therefore relatively high, which makes them less suitable for some applications.

2.High requirements for the medium: the ultrasonic flowmeter has high requirements for the medium, only the medium has a certain sound conductivity and sound permeability to measure, for some media with high viscosity or containing particles, the measurement accuracy of the ultrasonic flowmeter will be affected.

3.High installation requirements: The installation requirements of ultrasonic flowmeters are relatively high, and the sensor needs to be installed in the pipeline, and the position and angle of the sensor have a great impact on the measurement accuracy, if it is not installed properly, it will lead to inaccurate measurement results.

4.Affected by the environment: The measurement accuracy of the ultrasonic flowmeter is greatly affected by the environment, such as temperature, humidity, air pressure and other factors will affect the measurement results, so environmental calibration is required.

5.Regular maintenance required: Ultrasonic flow meters need to be maintained and calibrated regularly, otherwise the measurement accuracy and stability will be affected.

To sum up, although ultrasonic flowmeters have many advantages, there are also some disadvantages, which need to be selected and used according to the specific situation in practical applications.

High requirements for temperament, impurities, especially water or triethylene glycol and other liquids in natural gas, will adhere to the surface of the probe, affect the emission and reception of sound waves, and seriously affect the measurement; Ultrasound must not be present in the surrounding environment; There must be no electronic noise in the surrounding environment.
