FTB600 flow sensor Square wave pulse

Hello everyone,

I have been doing a lot of reading and website searching, but cannot find a way about how to wire and read the signal from FTB601 flow meter from OMEGA. Any suggestion and help in reading output from this flow meter is appreciated.

Here is the link for the flow meter and manual too.

No link, but sections 5 and 6 of the manual show the three wires and what to hook them to. Use 5 volts from the Arduino and ground, The signal goes to the pin of your choice on the Arduino.
