An Amateur Radio license is required to use certain frequencies or bands set aside for license holders and the FM radio band is NOT one of the bands. Per the FCC website: "Unlicensed operation on the AM and FM radio broadcast bands is permitted for some extremely low powered devices covered under Part 15 of the FCC's rules. On FM frequencies, these devices are limited to an effective service range of approximately 200 feet (61 meters)" That equates to very low power! Most likely about one tenth of a watt or less! If you break these rules it is a $10,000 fine! See More

I use an Arduino with interrupt routine. (every time the flowmeter creates a pulse, a software counter is activated) If you have no knowledge about Arduino (or any other microcontroler), I don't think this is something you can use.

Use the same method for the minimum and maximum temperature of each probe. Out lights up when the temperature recorded by the probe is far beyond the set point, but I'm not sure. See More
