PROBLEM TO BE SOLVED: To provide a magnetic coupling type flowmeter in which a driven body certainly follows a mover even when the flow rate rapidly varies.SOLUTION: The flowmeter includes a linear groove unit parallel with a flow channel extended outward from a flow channel having a circular cross section in a nonmagnetic metal duct. An extension section having a built-in magnet projected outside of a lateral outer peripheral surface of a cylindrical mover 3 is movable in the linear groove unit. A driven body 5 is disposed movably in a linear groove part parallel with a flow channel disposed on the lateral outside of a duct. A magnetic pole end face of the magnet 4 built in the mover 3 and a magnetic pole end face of a magnet constituting the driven body 5 are arranged in parallel so as to face each other. 【課題】流量が急激に変化した場合においても、確実に従動体が移動子に追従する磁気結合式の流量計を提供する。【解決手段】非磁性金属製管体内の円形断面の流路から外側に向かって延設された流路と平行な直線状溝部と、円筒形の移動子３の側方外周面より外側に突出された磁石を内蔵する延設部分が前述の直線状溝部内を移動可能とされ、従動体５が管体外側方に設けられた流路と平行な直線状の溝部内に移動可能に置かれ、移動子３に内蔵された磁石４の磁極端面と、従動体５を構成する磁石の磁極端面が平行に相対して配置されることを特徴とする。【選択図】図１
