The flow sensor is mainly divided into: a shunt, an electromagnetic current transformer, an electronic current transformer, etc. according to different measurement principles.
Electronic current transformers include Hall current sensors, Rogowski current sensors, and AnyWay variable frequency power sensors (for voltage, current, and power measurements) that are dedicated to variable frequency fuel measurements.
Compared with electromagnetic current sensors, electronic current transformers have no ferromagnetic saturation, transmission frequency bandwidth, small secondary load capacity, small size and light weight, which is the development direction of current sensors in the future.
