LDC0851EVM: small targets for LDC0851

Part Number: LDC0851EVM
Other Parts Discussed in Thread: LDC0851


Everywhere describes the detection of large metal plates for LDC0851EVM.
Can I detect a small targets by LDC0851? What should be done to detect a magnet or coil on the impeller of a standard flowmeters (see photo)?

It`s need to make a coil whose size is less than target, or tunes a coils by other manufacturers (such as SMD Inductors)?
