Identify Ultrasonic Flowmeter Manufacturers
When choosing an ultrasonic flowmeter manufacturer, we can actually see from the technical selection of engineers and the typical customers owned by the manufacturer. Next, we will introduce the selection of an ultrasonic flowmeter to Kepu, so that you can see whether it is a real manufacturer when communicating with the manufacturer of the ultrasonic flowmeter.The Working Principle of Ultrasonic Flow Meters
First, the basic principle of the ultrasonic flowmeter. When an ultrasonic wave propagates in flowing fluid, it carries information on fluid velocity. Therefore, the flow velocity of the fluid can be detected through the received ultrasonic wave, which can be converted into the flow rate. The ultrasonic flowmeter is a non-contact instrument that has been applied in recent ten years with the rapid development of integrated circuit technology. It is suitable for measuring the fluid that is difficult to contact and observe and the flow of large pipe diameters. The use of ultrasonic flow ratio does not require the installation of measuring elements in the fluid, so it will not change the flow state of the fluid and generate additional resistance. The installation and maintenance of the instrument will not affect the operation of the production pipeline, so it is an ideal energy-saving flowmeter.
The Application of Ultrasonic Flowmeters
The second is the application occasions. The portable ultrasonic flowmeter can be used for a wide range of media, including common clean water, tap water, circulating water, various lubricating oils, edible oils, etc. In addition, the portable ultrasonic flowmeter is also compatible with pipes made of various materials, from common iron pipes, carbon steel pipes, and stainless steel pipes, to various aluminum copper pipes, PVC pipes, glass pipes, and other pipes, and it can be easily competent to select sensors with a response. Therefore, it is widely used in environmental protection, petrochemical, metallurgy, paper making, food, pharmaceutical, and other industries.
The Features of Portable Ultrasonic Flowmeters
Then there are characteristics. The portable ultrasonic flowmeter is a real portable flowmeter with a very small volume and is lightweight. The portable ultrasonic flowmeter has the following seven advantages.1. Non-contact measuring mode, small size, lightweight, easy to carry.
2. The sensor is easy to install and suitable for measuring the acoustic medium of various sizes of pipes.
3. No need to damage the pipeline and stop production during the measurement.
4. Built-in rechargeable battery, which can work continuously for more than 12 hours.
5. Compact, solid, internationally advanced die-casting aluminum host.
6. Automatically memorize the accumulated traffic in the previous 64 days, 64 months, and 5 years.
7. Backlit LCD displays instantaneous flow, positive, negative, static cumulative flow, flow rate, time, analog input, and other data in Chinese.
Ultrasonic Flowmeter Selection
Finally, it is about parameters and model selection. Take the most common parameters, calibers, for example, there are three types of calibers, which are equipped with different sensors. DN15~DN100 pipes can be equipped with small sensors, DN50~DN700 pipes can be equipped with medium sensors, and DN300~DN6000 pipes can be equipped with large sensors. In addition to the caliber, there is also precision. Theoretically, there are two levels of accuracy. One is at the laboratory level, with an accuracy of 1%; The conventional accuracy is 1.5%~2.5%. But in fact, because of the bad working conditions on site, the accuracy often cannot reach the theoretical accuracy.
