#173933 - Counter IC for Ultrasonic flow meter
Hello,
I am working on Transit time method Ultrasonic flow meter for liqud flow.
In this method I transmit 200nano sec pulse on liquide pipe and start one counter in mega hirtz and after receiving echo i stop counter & use this count
in flow calculations.

Can any one suggest me any counter IC for this application.
Counter resolution must be in Pico or nano seconds.

Regards.
