5/29 · Pressure transient insensitive (PTI) mass flow controller is designed for semiconductor manufacturing. Model GF135 improves yield and uptime with real-time integral rate-of-decay flow measurement and advanced diagnostic capabilities. It can be used to verify

Increasing the fluid mass flow rate of the main stream enabled the two heat exchangers to be fully utilized and improved the overall heat transfer efficiency. The temperature of the cold fluid in the bypass was greatly increased after being heated by DFBR, which reduced the average temperature difference of EHE and heat transfer efficiency.

Model GFC thermal Mass Flow Controllers are designed to indicate and control set flow rates of gases. The GFC combines the characteristics, and accuracy of 

The FMA5400A/5500A Series electronic gas mass flow controllers provide for controlling the flow of a wide variety of gases from 0-10 SCCM up to 100 SLM. Utilizing heat transfer through a heated tube to measure molecular gas flowrate, the FMA5400A/5500A provides measurement of direct gas mass flowrate, without the need to compensate for

Since a flowing fluid removes a known quantity of heat as it passes, the temperature difference between the heated sensor and the flow stream is directly 

A thermal mass flow controller for controlling flow rate of a fluid of gas caused by the free convection between the heated thermal flow sensor and the 

The thermal gas mass flow controller is composed of a flow sensor, a diverter channel, a flow regulating valve and an amplifier controller. The gas flow sensor uses the principle of capillary heat transfer thermocalorimetry to measure the mass flow of gas (without temperature and pressure compensation).

How a laminar differential pressure-based mass flow controller works As the name implies, thermal flow meters and controllers use heat to measure the 

Feb. 3, 2013. Some of the earliest ideas for a thermal mass flow controller go back as far as 1911, when C.C. Thomas described a flowmeter containing a heated element with two thermometers Mass Flow Controller.
