There are many types of flowmeters, which will not be expanded introduce here. Some of them require magnets (Hall flowmeters), and some do not (photoelectric flowmeters). The following is how the magnetization direction of the flowmeter magnets looks like. Let me introduce to you.
For example, the magnetic ring used in the water flow sensor is basically radially magnetized, and the magnet material is mainly ferrite, such as sintered ferrite, injection molded ferrite, some with impeller, commonly used charging The number of magnetic poles is 2 poles, 4 poles, 6 poles, 10 poles, etc.
Our company is a professional motor magnet manufacturer. We can provide multi-pole ring magnets of various materials for the majority of motors, sensors, encoders, instruments, and precision electronic customers. If you need samples, please send us the size you need. , support non-standard customization.
