The AVF250S series is a Micro float flowmeter developed by ALIA, with simple structure and easy installation, which is very suitable for the measurement of small flowrate of gas or liquid. The design of the trimming needle valve is convenient to adjust the flowrate. Combined with the flow regulator, the flow purge device is formed to achieve constant flowrate output. The AVF250S is widely used in petrochemical, oil refining, fertilizer, steel, medicine and other industries.
