Abstract
A measuring unit 12 comprises a vibrator 13 which is disposed in a fluid flowing into the measuring unit 12 and is able to reciprocally vibrate in a direction of width of the flow passage when there occurs a differential pressure due to a flow velocity, a flow separator 15 which is disposed downstream of the vibrator 13 to abut with the vibrator 13 for holding the vibrator 13 in the measuring unit 12 and also separating the fluid, and forms a frequency converter 14 capable of supplying the differential pressure to the vibrator 13 from the upstream side so that the vibrator 13 can reciprocally vibrate, a vibrator abutting portion 16 disposed upstream of the vibrator 13 and coming into abutment with the vibrator 13 when the vibrator 13 is vibrated, and a frequency detector 17 capable of detecting reciprocal frequency of the vibrator 13.
