SITRANS FVA250 - Variable Area Flowmeter

SITRANS FVA250 is robust variable area flowmeter for precise measurement of liquids and gases in harsh conditions, including high pressures and temperatures.

SITRANS FVA250 is a robust variable area flowmeter for precise measurement of liquids and gases in harsh conditions, including high pressures and temperatures.

With its fully metal design, the SITRANS FVA250 flowmeter reliably measures a wide range of liquids and gases in closed piping systems—including corrosive and flammable media. A choice of flanges, liners and float materials meets the requirements of the pharmaceutical and chemical industries. Standard designs are available at short notice.

Achieve dependable readings for liquids and gases even under extreme conditions, supporting operational efficiency and safety.

Robust all-metal construction and impact-resistant housing reduce maintenance needs and extend service life.

Operate confidently in high-pressure and high-temperature environments, including corrosive and flammable media as well as potentially explosive atmospheres.

± 1.6% for liquids ± 2.0% for gases

Fitting: Stainless steel 1.4404/1.4571 Float: Stainless steel 1.4404/1.4571, Hastelloy, PTFE

Use variable area technology to monitor flow directly with a float principle for simple, visual indication and optional electronic output.

Configure with different flanges, liners and float materials to meet chemical, pharmaceutical, water or power generation requirements.

Add transmitters or limit switches for process monitoring and automation compatibility.

The SITRANS FVA250 operates on the float principle. The flowing medium lifts a conical float inside a measuring ring, increasing the ring gap until an equilibrium is established between the buoyant force of the medium and the weight of the float. The height of the float is directly proportional to the flow rate. This movement is transmitted magnetically to a display unit outside the measuring tube, providing a direct reading on the scale without the need for external power. For process monitoring and control, the device can also be equipped with a transmitter (MEM) with 4–20 mA and HART output, PROFIBUS PA or limit switches.
