FS4308-15-O8-BV-A FS4308-15-O8-BV-B Flow sensor

General Information:

• Product Series: It belongs to the FS4308 series of mass flow sensors, which are designed for general - purpose gas flow monitoring and control applications.
• Measuring Medium: Suitable for measuring the mass flow of gases.

Working Principle:

• The sensing elements adopt Siargo's proprietary MEMS (Micro - Electro - Mechanical Systems) thermal mass flow sensing technology (Thermal - D®). This technology measures the calorimetry and diffusivity of the flow medium. By adding a small amount of heat to the medium through a heating element on the microchip and using two temperature sensors symmetrically located above and below the heat source to detect temperature differences, the spread of heat, which is directly related to the flow rate, can be obtained.

Technical Parameters:

• Flow Range: Various mass flow ranges are available, typically from 0 - 10 slpm up to 0 - 50 slpm.
• Pressure Rating: Up to 1 MPa.
• Accuracy: ±1.5% + 0.2 fs.
• Output Options: RS485 or 0.5 - 5V DC.
• Pipe Diameter: The standard pipe diameter is 8 mm, and the model "15" in FS4308 - 15 - O8 - BV - A may represent other specific dimensions or characteristics, which need to be further confirmed according to the manufacturer's instructions.
• Temperature Range: -10°C to 55°C.

Structural Features:

• Connector: The standard connector is BS - PT 1/4", and one - touch connectors of 4 mm, 6 mm, or 8 mm are also available. Other customized connectors can be provided upon request.
• Sensor Surface: The sensor surface is passivated with silicon nitride ceramic materials and has a water/oil - proof nano - coating to improve performance and reliability.

Product Advantages:

• Compared with the conventional calorimetric flow sensing technology, this unique sensing method has better linearity, can eliminate gas sensitivity for gases with similar thermal diffusivities, and improves temperature performance. It can also auto - recognize pre - programmed gases with significant differences in thermal diffusivity. It is the first - of - its - kind in the industry to sense the mass flow of multiple gases without a manual gas conversion factor, ensuring high - precision gas measurement with air calibration.

Application Areas:

• It can be used for flow monitoring of air or nitrogen in the purification industry, and is also applicable to the environmental detection industry (such as air samplers) and analytical instruments (such as chromatographic analyzers), etc.
