A flow meter unit that detects the flow rate is interposed, and when the differential pressure between the upstream side and the downstream side of this flow meter unit increases, the valve element separates from the valve seat and becomes open, and the flow meter unit detects the flow rate. What is claimed is: 1. A flowmeter equipped with a safety valve that allows fluid to flow from the side to the downstream side, the flowmeter comprising a safety valve, characterized in that means for blocking the flow path of the safety valve is detachably provided in the housing. (2) In the middle of the flow path formed in the housing,
A flow meter unit that detects the flow rate is interposed, and when the differential pressure between the upstream side and the downstream side of this flow meter unit increases, the valve element separates from the valve seat and becomes open, and the flow meter unit detects the flow rate. In a flowmeter equipped with a safety valve that allows fluid to flow from the side to the downstream side, the safety valve is characterized in that a means for keeping the valve body of the safety valve in a state seated on the valve seat is detachably provided in the housing. Equipped with a flow meter.
