Reasons for using ceramic tubes for capacitive electromagnetic flowmeters

1. Working principle of capacitive electromagnetic flowmeter

Capacitive electromagnetic flowmeter is a device that uses Faraday's law of electromagnetic induction to measure the volume flow of conductive liquid. Its working principle is to measure the conductive liquid moving in the medium through the electromagnetic field induction electrodes installed on both sides of the medium pipe. When a conductive liquid flows through the measurement pipe, the movement of ions in the liquid will generate an electromotive force, which triggers an electric potential on the sensing electrode. The volumetric flow rate of the liquid is calculated by measuring the capacitance change of the electrode.

The advantages of electromagnetic flowmeters are high accuracy and wide measurement range. They are suitable for measuring a variety of conductive media, but they have certain requirements for pipeline materials.

2. Why choose ceramic tube?

1. Good corrosion resistance

Ceramic materials have good corrosion resistance. Their main components are alumina or silicate, etc., and have high chemical stability and insulation. performance. This makes the use of ceramic tubes in media flow measurement more reliable.

2. Good high temperature resistance

Because of its good chemical stability, ceramic materials can withstand fluid media in high temperature environments without expansion or contraction and other deformation phenomena, thus ensuring Improve the reliability of the flow meter.

3. Good wear resistance

The hardness of the ceramic tube is very high, and it is not easy to be worn or damaged when the liquid passes through the pipe. Even in high-speed flow measurement, it can ensure a certain degree of wear and tear. stability.

In summary, ceramic tubes, as pipe materials for capacitive electromagnetic flowmeters, have obvious advantages, especially in some situations with high medium flow and complex environmental conditions.

Capacitive electromagnetic flowmeter uses ceramic material as pipe material, which has good corrosion resistance, high temperature resistance and wear resistance, ensuring the flow meter accuracy and reliability.
