Metal Tube Rotameter

Model / Series: AN-F-ZZ006

All-metal variable-area (rotameter) flow meter with local indication and optional remote transmission.

Bore: DN15–DN150
Other: Local display + smart remote optional; 4-20mA/RS485; all-metal anti-vibration; high-temp/pressure; anti-corrosion custom
Range: Accurate small-flow metering, multiple range steps
Medium: Liquids, gases, low-pressure steam
Installation: Vertical flange, threaded; vertical pipe

Function

The metal tube rotameter monitors flow using the balance of buoyancy and gravity, giving a direct local indication of instantaneous flow for liquids and gases; smart versions support remote signal output. It provides intuitive local readings, and with a transmitter module offers 4-20mA output and RS485 for remote monitoring, data logging and flow regulation via automation systems.

Features & Advantages

Rugged all-metal construction is impact-resistant and durable, withstanding high temperature and pressure for harsh conditions. Stable, clearly visible measurement with local reading requiring no external power, while remote versions suit automation networking. Stable accuracy, very low failure rate and easy maintenance, meeting international export standards for small and medium overseas metering.

Applications & Industries

Used in chemicals, petroleum, power, water treatment, pharmaceuticals, light industry and environmental protection for small-flow process monitoring and equipment-mounted local measurement in domestic and overseas projects.

Models & Options

Bores DN15–DN150 in local-indicating and smart remote types; stainless steel housing and measuring tube; anti-corrosion, high-temperature and high-pressure options; threaded and flange mounting; multi-standard conditions and OEM branding for export.
