Siemens Coriolis Flow Meter: Sitrans FC High-Precision Mass Systems

Quick Answer

Silver Automation Instruments supplies Siemens Sitrans FC Coriolis mass flow meters to process plants and OEMs in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. These meters measure mass flow directly and ignore changes in density, viscosity, or conductivity. You get ±0.1% mass flow accuracy for liquids and a 100:1 turndown ratio in a single instrument. Send your pipe size DN, fluid name, pressure, temperature, and flow range to receive a specific quote.

Why the Sitrans FC Excels in Real Installations

In practice, indirect flow measurement drifts with fluid property changes. The Coriolis sensor inside the Sitrans FC uses a vibrating tube pair. Mass flow determines the phase shift between two sensing coils on the tube. Temperature and density values come from the same sensor signal. Here is the thing, you do not need to install upstream or downstream straight pipe lengths. The meter fits directly into tight locations like offshore wellhead skids or chemical injection panels. We have seen this advantage many times on customer sites in Vietnam and Saudi Arabia.

Models include the FC410 for general purpose use, the FC430 with advanced digital processing and Modbus TCP, and the FC440 for custody transfer. The FC430 is the volume model when engineers want HART 7 with detailed diagnostic data. Silver Instruments holds stock of the FC430 in DN15, DN25, DN40, and DN50 sizes for fast shipment.

Technical Parameters That Affect Your Selection

Mass flow accuracy for liquids is ±0.1% of actual flow rate. For gases it is ±0.5%. Density accuracy reaches ±0.0005 g/cm³. Temperature is measured via a built-in PT100 element with an uncertainty of ±0.2 °C. The process temperature range covers -50 °C to +200 °C. Flow spans start from 0.1 kg/h on a DN15 sensor and reach 320 000 kg/h on a DN150. Wetted materials are 316L stainless steel or Hastelloy C22. Aggressive fluids like sulfuric acid or wet chlorine demand Hastelloy. Process connections are flange type from DN15 up to DN150, with threaded options available on smaller sizes. Output options include 4-20 mA HART, Modbus RTU, Modbus TCP, and Profibus PA. Certifications cover ATEX Zone 1 and 2, IECEx, and SIL 2 for safety instrumented functions. Power supply is 24 V DC nominal.

Industry Scenarios Where the Meter Delivers

Oil and gas operators use the Sitrans FC for wellhead production allocation. They need mass flow instead of volume b

ecause crude oil density shifts between wells. A customer in Oman replaced turbine meters with FC430 units and eliminated the monthly recalibration routine. Chemical sites use the meter for batching catalysts and solvents with very low overrun. A paint manufacturer in Indonesia built a dosing system with FC430 DN15 meters. The plant cut solvent waste by 2.3 percent because the meter reads mass directly and ignores morning temperature drift. Food and beverage plants apply it for raw milk intake, CIP fluid monitoring, and sugar syrup dosing. Because the tube is self-draining and cleanable, it suits hygienic lines. Marine vessels measure heavy fuel oil and lube oil for fuel consumption monitoring. A ship operator in Brazil installed an FC410 on the fuel inlet line and now retrieves accurate consumption data without density correction tables.

Frequently Asked Questions

Q: What is the maximum turndown of the Sitrans FC?
A: Typical turndown is 100:1 for mass flow. You can measure from 1% to 100% of the rated maximum flow and stay within the published accuracy limits.

Q: Can the Sitrans FC output density and temperature?
A: Yes, every FC sensor provides density with ±0.0005 g/cm³ accuracy and temperature from the PT100 element. This helps with product concentration checks and interface monitoring.

Q: What hazardous area certifications apply?
A: The meter carries ATEX Zone 1 and Zone 2 certifications, IECEx, and meets SIL 2 requirements for safety instrumented loops.

Q: Do I need a straight pipe run before the meter?
A: No straight run is required. The Coriolis measuring principle does not need flow conditioning. You can mount the meter directly after a pump, elbow, or valve.

Q: How do I get a firm price for a DN40 Sitrans FC430?
A: Email [email protected] with your full process conditions. We provide a quotation within one business day and can ship from our stock in Singapore or arrange factory dispatch.
