In the petroleum, chemical, water resources and other areas that use flowmeters the most, the most common is the ultrasonic flowmeter and electromagnetic flowmeter, why these two meters will become the first choice to be widely used? Let's analyze their main advantages.
1. Wide range of applications
Electromagnetic flowmeters can measure a variety of acid and alkali liquids, sewage, pulp and other conductive media, while non-conductive ultra-pure water, pure water, water and other non-conductive liquid media can be measured with ultrasonic flowmeters, so the two meters can measure almost all common liquids after combining;
2. High measurement accuracy
In terms of flow measurement, it can be said that the higher the accuracy, the better, the two instruments are very good in terms of accuracy, conventional accuracy 1.0, slightly higher requirements of 0.5, the highest can reach 0.3, or even 0.2 accuracy, at present, the performance of various flow measurement instruments is very good;
3. No pressure loss for free flow parts
Whether it is an electromagnetic flowmeter or an ultrasonic flowmeter, there are almost no parts inside the flow tube, so it will not hinder the medium and there will be no pressure loss. However, the electromagnetic flowmeter will be limited by some ultra-high pressure situations, then you can use an external clamp-type ultrasonic flowmeter, and the pressure will not have any impact on the flow measurement;
4. Easy to install
Generally speaking, the industrial field measurement flow is connected with a flange, which is inconvenient to damage the existing pipe can be installed with an external clamp, which is very convenient;
5. High cost performance
In addition to requiring ultra-high precision, the price of these two instruments is relatively close to the people, and the public can accept.
