SITRANS FVA250 Variable Area Flowmeter Technical Data and Engineering Selection Guide
SITRANS FVA250 Variable Area Flowmeter is supplied by SANTAN for new projects, installed-base replacement and complete model-code review. Use the verified product-family data below for preliminary selection and quotation preparation.
Verified Technical Specifications
| مبدأ القياس | Float-type variable-area measurement with magnetic indication transfer |
|---|---|
| Media | Liquids, gases and steam, subject to sizing and material compatibility |
| الدقة | ±1.6% for liquids; ±2.0% for gases |
| Ambient temperature | -40 to +80 °C |
| Connections | EN 1092-1 and ANSI flange configurations |
| Wetted choices | Stainless-steel fitting; stainless steel, Hastelloy or PTFE float choices |
| الحماية | IP65/IP66 |
| Options | 4–20 mA/HART, PROFIBUS PA or limit-switch options; ATEX configurations |
Published values describe the product family and are configuration dependent. Final range, materials, accuracy, pressure, temperature, approvals, communications and accessories must be checked against the selected Siemens article number and current documentation.
Best-Fit Application
Use FVA250 for robust local flow indication and optional signal/limit outputs when the fluid, range, density, viscosity, pressure and temperature are known. Each scale is application sized; do not select only by pipe diameter.
Quotation and Selection Data Required
| متوسط | Liquid or gas, composition, conductivity, density and viscosity as applicable |
|---|---|
| Flow data | Minimum, normal and maximum flow; operating and reference conditions |
| Mechanical | Line size, schedule, connection standard, orientation and available straight run |
| Design limits | Operating/design pressure and temperature; wetted-material requirements |
| Electrical | Power, output/protocol, enclosure and hazardous-area requirements |
| Documentation | Required calibration, inspection, material and compliance certificates |
