HH30 is a well-known PMS star in Taurus. HST observations have revealed a flared, edge-on disk driving a highly-collimated jet. Plateau de Bure observations of the 13CO(2-1) emission allow us to study the disk avoiding confusion from the outflow and the ambient cloud. Model fitting the uv-plane visibilities gives the following results: i) The disk outer radius is 380+-20 AU; ii) The disk rotation is Keplerian; iii) Using a distance of 140pc and the magnitude of the Keplerian rotation, we deduce a mass of 0.67+-0.04 Msol for the protostar.
