After the cannula 3 is inserted from the mounting hole on the flange, the flaring block 4 does not completely extend from the inside of the mounting port. The flaring blocks 4 at the ends of the cannula 3 fit together to form a truncated cone, and the outer ends of the flaring blocks 4 are all provided with arc chamfers, which are more convenient when the cannula 3 is inserted. Magnetic blocks 7 are fixed on the inner sides of the flaring blocks 4. The magnetic blocks 7 on the inner sides of the flaring blocks 4 fit each other to avoid the flaring blocks 4 automatically expanding during the insertion process and affecting the installation. A push rod 5 is slidably installed inside the cannula 3, and the push rod 5 extends from the end of the flaring block 4 to the outer end of the cannula 3. The end of the flow meter body 1 close to the fixed disk 2 is threadedly installed with an internal threaded disk 6.
