Emerson Coriolis Mass Flow Meters consist of two main components: the flow sensor and the transmitter. The flow sensor includes a measurement tube, support bridges, a vibration excitation system with drive coils, optical or electromagnetic detection probes, and temperature sensors to compensate for mat...
If the MS does not pump down correctly, see the manual or online help for information on troubleshooting air leaks and other vacuum problems. 9 Turn on the carrier gas flow after the vacuum pumps have been running for 15 minutes. 10 When prompted, turn on the GC/MS interface heater and ...
Theory of Operation The model FT4A is an innovative thermal gas mass flow meter and temperature transmitter. It is microprocessor-based and field programmable. The FT4A thermal sensor operates on the law that gases absorb heat. A heated sensor placed in an air or gas stream transfers heat in...
Action: If your flow readings won't change regardless of actual flow, your flow sensor may be damaged. Please contact support to troubleshoot (page 12 ). 22 Troubleshooting and Maintenance Issue: Can I use the meter with other gases? Action: Yes! Your flow meter is designed specifically to...
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure the mass flow rate of air and gases. Fox Models FT2A and FT3 are equipped with the PowerPro™ Sensor, while Models FT1, FT4A & FT4X have the DDC-Sensor™. Both thermal mass flow se...
During operation process gas enters the instrument's flow body and divides into two flow paths, one through the sensor tube, the other through the la- minar flow element bypass. The laminar flow bypass generates a pressure drop, P1–P2, forcing a small fraction of the total flow to pass ...
