About Georg Fischer GF Rotameter VAFM Detail

Variable area flow meters from GF Piping Systems are dismountable meters for flow measuring in industrial piping applications.The measurement ranges, which are attuned to our customer needs, and the range of materials available for the tubes andconnection ends, mean that the flow meters can be used for a wide range of applications and a great variety of media.

Reliable Flow Measurement for Industrial Applications

The GF Rotameter VAFM delivers precise flow monitoring for water and neutral liquids in diverse industrial environments. Its mechanical structure eliminates the need for external power, and the direct-reading scale allows for straightforward operation. The range of available end connections including threaded, socket, and flanged, as well as multiple material options, ensure high compatibility with specific installation requirements.

Durable and Service-Friendly Design

Engineered using high-grade PVC, PP, or PVDF materials, the VAFM withstands temperatures from -10C to +60C and pressures up to 6 bar. The transparent tube allows for easy visual inspection, while the units field serviceability and low maintenance needs make it a practical choice for continuous operation. Compliance with EN ISO 9001:2008 assures quality and reliability.

FAQs of Georg Fischer GF Rotameter VAFM:

Q: How does the GF Rotameter VAFM measure liquid flow?

A: The GF Rotameter VAFM measures flow through a transparent, tapered tube with a float inside. As liquid flows upward (in a vertically mounted position), the float rises and stabilizes at a level corresponding to the flow rate, which can be read directly from the scale on the tube.

Q: What are the main benefits of using the VAFM Rotameter in industrial applications?

A: This rotameter provides high accuracy (4% F.S.), does not require power, and features a clear, direct-reading scale. Its robust construction, easy installation, and low maintenance make it ideal for continuous, reliable service in demanding industrial environments.

Q: When should I choose PVC, PP, or PVDF as the material for my VAFM rotameter?

A: Material selection depends on the chemical compatibility with your process liquids and environmental conditions. PVC is common for general water applications, PP offers improved chemical resistance, and PVDF is ideal for aggressive media or higher temperature requirements.

Q: Where is the ideal mounting position for the GF VAFM Rotameter?

A: The VAFM rotameter must be installed in a vertical position with the fluid flowing upwards. This ensures correct operation and accuracy, as the floats movement corresponds directly to the flow velocity in this orientation.

Q: How do I select the right size and flow range for my application?

A: Choose the rotameter model based on your expected flow range (e.g., 5-1000 L/h) and required port size (DN15 to DN50). Also, consider your media type and process conditions to ensure compatibility with available materials and sealing options.

Q: What is the maintenance process for the VAFM rotameter?

A: Routine maintenance involves periodic visual inspection, cleaning the tube and float to remove buildup, and checking seals for wear. Its field-serviceable design allows for easy disassembly and reassembly without specialized tools.
