Metal Tube Rotameter

The OVAF series metal tube rotameter measures flow by floating a float within a vertical metal tube. As flow increases, the float rises, and in connection the pointer indicating the flow rate. Advantages include rugged construction, high durability, and suitability for a wide range of gases and liquids, even under high-pressure conditions. The series Metal Tube Rotameter can be pure mechanical flowmeter or pair with electronics to achieve signal output.
