Asmke Micro Metal Tube Rotor Flowmeter Rotameter

Description: The micro-metal tube float flowmeter is a variable area flowmeter based on float position measurement. The new design makes it possible to measure tiny flows. It is particularly suitable for measuring tiny flows of liquids and gases.It adopts an all-metal structure with small size, small pressure loss, and large range ratio (10:1). It is widely used in various industries in complex and harsh environments, and is used for flow measurement and process control of tiny flows, low flow rates, and var
