Flow meter

Abstract

A flow meter includes a transparent base, a regulating valve, an outlet connector, a positioning member, two clamping members, a pressure assembly, and a flow scale. The transparent base has a first port, a second port, a fixing part connected to one end of the second port on the pipe side, and a conical flow hole located inside the transparent base and communicating with the first and second ports. The regulating valve is connected and fixed to the first port and includes an inlet connector and an adjustment knob fixed to one end of the inlet connector to adjust the flow rate. The outlet connector is connected and fixed to the second port. The positioning member is used to fit and fix the regulating valve and the outlet connector. The two clamping members are each clamped to a plurality of positioning rods on the outer sides of the two frames of the transparent base to prevent them from coming off due to vibration. The pressure assembly is fixed to one end of the transparent base by a fixing member passing through the fixing part and the pressure assembly, increasing the fixing force of the pressure member.
