FRDM-KL25Z and multiple hall sensors

Hi All,


Requirement :

Count the pulses generated by hall sensor inside a flow meter.  The hall sensor produces around 330 pulse / second.  There would be around 6-10 flow meters connected to a circuit for calculating the total consumption.


Is frdm-kl25z my best bet to start this project or is there any other better alternative available.  


I am thinking of using the GPIO pins in interrupt mode to count the pulse.  Can multiple interrupts work without data loss parallely. Can the MKL25Z128VLK4 MCU handle this.
