The domestic market saw the introduction of ultrasonic flowmeters. The ultrasonic flowmeters manufactured by Fuji Electric Co. , Ltd. and Tokyo Keiso Co. , Ltd. are distributed in China by Dalian Sonya Instrument Co. , Ltd. , a company that was founded in 1992 and is based in Dalian, Shandong Province, China. The chief technical engineer of the card initially started to gradually contact and study the ultrasonic flowmeter. Following this, Dalian Sonica started to independently develop the ultrasonic flowmeter under the direction of Mr. Wang.

When measuring or detecting flow in industrial settings, an ultrasonic flowmeter is required to be present. This is because, according to the current conditions of the market, ultrasonic flowmeters are widely used in certain water treatment flow detection. In contrast to the pipeline flowmeter, which is only capable of measuring one pipe caliber's worth of flow, the ultrasonic flowmeter can detect the flow of multiple pipe calibers due to its portability, portability, ease of installation and use, and relatively large flow detection range. This allows it to detect the flow of multiple pipe calibers.

The SIN-2000H ultrasonic flowmeter is a hand-held ultrasonic flowmeter that is currently receiving widespread praise from the market and is in high demand in the industrial sector. The market demand for handheld ultrasonic flowmeters is high, which has also led to an increase in the number of domestic manufacturers of ultrasonic flowmeters. This has also made it difficult for the majority of users to select electromagnetic flowmeters because there are so many options available.

When an ultrasonic beam moves through a liquid, the flow of the liquid will cause a slight change in the amount of time it takes for the beam to move through the liquid. This change in the amount of time it takes for the beam to move through the liquid is proportional to the flow velocity of the liquid. Both sensors take exactly the same amount of time to transmit and receive sound waves when there is no flow (the only technology that can actually measure zero flow), but when there is flow, the travel time of the sound wave in the upstream direction is longer than that in the downstream direction. At zero flow, both sensors take exactly the same amount of time to transmit and receive sound waves.

A portable or handheld ultrasonic flowmeter, also known as an energy meter, can be used to measure the flow and heat of a variety of single-phase liquids that are capable of transmitting ultrasonic waves. An ultrasonic flowmeter that is portable and handheld uses a non-contact measurement method, has a large measurement range, contains no moving mechanical parts, and is unaffected by system pressure and harsh environments. It has proven effective in a variety of water environments, including fresh water, salt water, sewage, chemical liquids, rivers, and others. The measuring of fluids such ultrasonic level sensors for liquids as water, fuel oil, and others.

Handheld, clamp-on, and wall-mounted ultrasonic flowmeters are the primary categories that fall under the umbrella term "ultrasonic flowmeters. "The portability of the ultrasonic flowmeter, its ease of carrying, installation, and operation, as well as its relatively large flow detection range, are the primary advantages of this type of flowmeter. It is able to detect the flow in pipes of a variety of diameters. In contrast to the pipeline flowmeter, it is not capable of measuring anything other than the flow of a calibre.

It is inevitable that there will also be some drawbacks associated with the advantages. There is a possibility that the accuracy of ultrasonic flowmeters is not nearly as high as that of pipeline flowmeters, which is the potential for the ultrasonic flowmeters to be the most significant drawback. A steady flow of fluid, on the other hand, helps to stabilize the measurement, which contributes to the accuracy of the measurement. The measurement data, on the other hand, will be unreliable or impossible to measure if the fluid in question has a state of chaotic flow. It is necessary to use an extension bracket whenever the pipe being measured has a diameter that is greater than DN300. When measured with the extension bracket, the diameter of the pipe must be at least DN700 and cannot be less than that. The extension bracket can be attached to the wall using either the V method or the Z method; however, the Z method is the one that is generally recommended for installation because it results in a stronger signal.

When it comes to the installation of clamp-on sensors, you can choose between the V method and the Z method.

V methodIt is recommended to use the V method for pipelines ranging from DN15mm to 200mm. During the installation process, the two sensors are positioned so that they are aligned horizontally, and non contact radar level transmitter the center line is aligned so that it is parallel to the axis of the pipeline. It is important to note that the direction of the emission must be in the opposite direction (the direction in which the two sensors face inward). The V method is distinguished by its straightforward application and precise measurement capabilities. When it comes to pipes with a diameter less than DN50mm, the installation accuracy is very good. Please make sure that you are paying attention to the parameters of transmission time ratio, signal strength, and signal quality.

Z methodWhen the signal cannot be detected by the V method or the signal quality is poor, the Z method should be used instead of the V method. The Z method is also the method of choice for pipes with a DN200mm-6000mm. When installing, ensure that the two sensors are on the same axis, and pay attention to the emission directions, which must be opposite (the direction of the two sensors faces inward). The vertical distance between the two sensors along the tube axis should be equal to the installation distance. Because the ultrasonic waves are transmitted and received directly in the medium propagation when using the Z method, the signal does not have any reflection, and as a result, the signal strength attenuation is kept to a minimum. Because of this, the Z method has a stronger signal strength and is appropriate for situations in which the ultrasonic signal attenuation is relatively high. These situations include scaling in the pipeline, large caliber, impurities or bubbles in the medium, and large caliber.

The following will provide an overview of the process of installing the point. The key to accurate measurement is the careful selection explosion proof level sensor of the point at which the installation will take place. When deciding where to put an installation point, you need to take into account the impact of a number of factors, including whether or not the pipe is full, whether or not the flow is steady, whether or not there is fouling, and whether or not there is interferenceFilling the pipe with fluid at the measurement point is necessary in order to guarantee accurate and consistent results from the measurement. As a result, the following prerequisites need to be satisfied before installation can begin:To avoid the phenomenon of dissatisfaction in the upper part, air bubbles or precipitation in the lower part, the two sensors should be installed in the horizontal direction of the axial surface of the pipe, within the range of 45 degrees as shown in Figure 2. The sensor's readings are perfectly normal.
