Ultrasonic flowmeter is an instrument that calculates the flow rate by measuring the ultrasonic propagation speed in the fluid. It has the characteristics of non-contact measurement, high precision, good stability, strong adaptability, easy installation and maintenance. The following is a detailed guide to the price, performance, brand and other aspects that need to be considered when purchasing ultrasonic flowmeters:
Price
The price of ultrasonic flowmeters varies depending on the brand, model, function, measurement range and other factors. In general, the price of portable ultrasonic flowmeters is relatively low, while the price of high-precision, multi-functional ultrasonic flowmeters is higher. In addition, there are also differences in the price of different brands of ultrasonic flowmeters. Therefore, in the purchase, should be based on their own needs and budget for comprehensive consideration, choose cost-effective products.
Property
- Measurement accuracy: The measurement accuracy of ultrasonic flowmeters is usually within ±1%, and the accuracy of some high-end models can even reach ±0.5% or higher. The high-precision ultrasonic flowmeter can provide more accurate measurement results, and is suitable for occasions where the measurement accuracy is required.
- Stability: Due to the non-contact measurement, the ultrasonic flowmeter is not affected by changes in the physical properties of the fluid, such as temperature, pressure, viscosity, etc., so its stability is good. Ultrasonic flowmeters with good stability can maintain the accuracy of measurement results for a long time.
- Measurement Range: Ultrasonic flowmeters can measure a variety of fluids, including gases, liquids and slurries, and are not affected by fluid turbulence, particles and impurities. At the same time, it can also measure two-way flow and has a wide range of applications. At the time of purchase, the appropriate measurement range should be selected according to your own measurement needs.
- Installation method: The installation method of ultrasonic flowmeter includes external clamp type, insert type and pipe segment type. External clamp-type ultrasonic flowmeter is easy to install and does not require downtime and maintenance; The plug-in ultrasonic flowmeter needs to be shut down and installed, but the measurement accuracy is high. The pipe segment ultrasonic flowmeter needs to be installed in the pipeline, which is suitable for occasions where the measurement accuracy is very high. At the time of purchase, you should choose the appropriate installation method according to your actual situation.
Brand
There are many brands in the ultrasonic flowmeter market, such as Siemens, Emerson (Micro Motion), KROHNE, Endress+Hauser, Q&T, Aister and so on. These brands are outstanding in terms of technology, performance and service, and can meet the needs of different users. When choosing a brand, consider the following factors:
- Brand awareness: Well-known brands usually have better technical strength and more perfect service system, can provide more reliable products and better service.
- User word of mouth: User word of mouth is one of the important criteria to measure the quality of a brand. You can understand the user reputation of the brand by viewing user reviews, consulting professionals and other ways.
- After-sales service: Good after-sales service can ensure that the problems encountered in the process of use are solved in time, improve the efficiency and satisfaction. Therefore, when choosing a brand, you should pay attention to its after-sales service.
Other notes
- Understand product characteristics: Before purchasing, you should understand the characteristics, functions and methods of use of the product in detail to ensure that the product meets your needs and use habits.
- Choose regular channels: When purchasing, you should choose regular channels to avoid buying fake and shoddy products. You can choose official websites, authorized agents or well-known e-commerce platforms and other channels to purchase.
- Pay attention to maintenance: In the process of use, attention should be paid to the maintenance of the ultrasonic flowmeter to ensure its long-term stable operation. You can regularly clean sensors and check the integrity of components such as cables to discover and deal with potential problems in a timely manner.
In summary, the purchase of ultrasonic flow timing needs to consider multiple aspects such as price, performance, brand and other considerations. Through careful comparison and selection, you can find the best product for you.
