PROBLEM TO BE SOLVED: To provide a fluid vibration type flowmeter that can be developed in a short time at a low cost by changing the height of two-dimensional flow passage in the case of developing flowmeters having different measurement capacities. SOLUTION: In the case that the width of nozzle flow passage 210 is W, height of target 3 is H, diameter of outer face of target 3 isΦ, radius of concave of target 3 is R, depth of concave of target 3 is h, they have following relationship. H/W=2.4355 to 7.1786,Φ/W=1.817 to 3.7, R/W=0.629 to 1.4643, h/W=0.3167 to 0.7.
