How to select the material of the measuring tube of the electromagnetic flowmeter

Whether the electromagnetic flowmeter can smoothly carry out the normal operation of each structure in the flowmeter is very important, and the measurement and conduction is a factor that carries the normal passage of the electrical liquid of the conductor under test. First, it can be said that measuring the normal operation of the catheter in the entire flowmeter is very important, so the requirements for the material of the measuring catheter are generally higher.

Usually, the measuring catheters we see are made of non-magnetic materials. It should be said that non-magnetic conduction is one of the most critical factors to ensure the normal operation of the electromagnetic flowmeter. It is necessary to have a certain mechanical strength, for example, to have low electrical conductivity, low thermal conductivity, etc., so it is also possible to use FRP, stainless steel, or some high-strength plastics in the industry. Of course, what kind of materials should be used specifically should say that different industries will have different requirements, and the key to the industry is to have strong applicability and meet the characteristics of normal operation.

In short, the selection of the material of the measuring tube of the electromagnetic flowmeter should pay attention to one principle, that is, the shunt that is measured and guided can not be short-circuited, electromagnetic waves are not generated, and materials with low thermal conductivity are selected as much as possible, so that it can be made more A wider range of applications in a wide range of industries can also make their work performance more stable.
