Production materials and principles

The main materials of electromagnetic flow meter include conductive liquid flow tube, magnetic field generator and probe. When the conductive liquid passes through the flow tube, an induced electromotive force perpendicular to the direction of the liquid and the magnetic field will be induced. The magnitude of the electromotive force is proportional to the flow rate of the liquid, so the flow rate of the liquid can be determined by measuring the magnitude of the induced electromotive force.

A magnetic field generator usually consists of an electromagnet and a permanent magnet. The electromagnet generates a strong magnetic field by energizing it, and the permanent magnet provides a constant magnetic field. The superposition of these two magnetic fields creates a strong and stable magnetic field that is used to induce the electromotive force in the liquid.

The probe is used to detect the induced electromotive force and convert it into an electrical signal that can be read. The probe usually consists of a coil and a circuit board. When the induced electromotive force passes through the coil, an induced current is generated. After amplification and processing, an electrical signal proportional to the liquid flow rate can be output.

What are the differences between electromagnetic flow meter with different prices?

The price of an electromagnetic flow meter is usually related to factors such as its measurement accuracy, materials, and manufacturing processes. Generally speaking, higher-priced electromagnetic flow meter usually have higher measurement accuracy and more durable materials, and are more suitable for use in harsh environments. In addition, higher-priced electromagnetic flow meter usually have more functions and better self-diagnosis and self-calibration capabilities.

Of course, electromagnetic flow meter produced by different manufacturers will also have certain price differences. Some well-known brand manufacturers, such as Doweston, Rosemount, etc., usually have higher prices, but their product quality and service will also be more guaranteed. The prices of electromagnetic flow meter produced by some small manufacturers are relatively low, but the product quality and after-sales service are not guaranteed.

In general, choosing an electromagnetic flow meter that suits your application scenarios and needs is the most important, and price is only one factor. Before purchasing, it is recommended that users carefully compare and evaluate electromagnetic flow meter of different brands and models to choose the product that best suits them.
