By winning the Open Finland with the youth in 2006, Ron was allowed to participate in the World Darts Trophy 2006, where he became youth champion by winning 6-1 in legs against Sven van Dun in the final. Since Meulenkamp joined the men division, he has won one international WDF tournament; the France Open 2006.

In March 2007 Meulenkamp switched to the PDC. At the time, he was ranked 833rd in the Order of Merit. In about six months he rose to 173rd place, but already in September 2007 he decided to return to the BDO. In 2014 Meulenkamp made the switch to the PDC again.

Ron played his first PDC World Championship in 2015, which he earned for being the 2nd highest unqualified European player on the Pro Tour Order of Merit. Ron won a 2-year tour card at Q school in 2016.

When Ron is not playing darts, he regularly works as a darts analyst at Viaplay.
