WebConversion Factor for Helium for FMA-8500 Models: 1.389 Flow Rate of Helium: (0 to 1000 SCCM) x 1.389 = 0 to 1389 SCCM Description: The FMA-8506 Mass Flow Sensor has a linear 0 to 5 Vdc output. When used with Helium gas, the output will be proportional to a flowrate of 0 to 1389 SCCM. Actual Flow Rate of Gas = Flow Rate x Correction of … WebTo determine corrected flowrate: find the gas for which the meter is calibrated in the left column, move to the right to the gas that is being used. Multiply the flowrate indicated on the meter by the correction factor. … curia vescovile frosinone

WebThe FS5002 are mass flow sensors for gas. They come in various calibrations from 50 sccm up to 1000 sccm with both analog and digital outputs. The series covers a wide dynamic flow range with a working pressure rating of up to 0.5 MPa (5 bar or 73 psi) and a compensated temperature range from -10°C to 55°C. Webmass flow would be 100 sccm. If the gas were N2, the gas flow would be, = 100 sccm x (GCFN2 / GCFAr) = 100 sccm x (1.0 / 1.39) = 72 sccm Note: 1. When using the GCF, the accuracy of the flow reading may vary by +/-5%. 2. The repeatability remains within +/-0.2% FS. Mass flow controller gas correction factors for common gases are available at WebThermal-based Mass Flow Controller Gas Correction Factors. Thermal-based mass flow controller gas correction factors for various gases with respect to Nitrogen. Please note that a non-linearity may exist between a Nitrogen calibration and the actual flow of process gases. Thermal-based Mass Flow Controller Gas Correction Factors. maria chiara de biasio
