Abstract
A flow meter comprises a flow tube, a magnetic switch and an adjustment assembly. The flow tube has two ends screwed respectively with a first fastening member and a second fastening member, and includes a jutting seat, a sleeve, a magnetic element and an elastic element inside. The magnetic switch is located on a lateral surface of the flow tube, and includes a magnetic induction member disposed inside to form magnetic induction with the magnetic element and a first gear rack. The adjustment assembly engages with the first gear rack for control. When the sleeve is pushed by liquid to generate displacement alteration, distance between the magnetic induction member and sleeve can be quickly adjusted by the adjustment assembly. In the event that the magnetic element in the sleeve exceeds the limit range of the magnetic induction member, a notice is sent to shut down electric power.
