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.

CODA KC-Series Coriolis Mass Flow Controllers provide high-accuracy liquid flow control even when fluid composition is changing or unknown. LC-Series Liquid Flow Controllers rapidly

The entire flow stream was heated, and the thermometers measured the temperature rise (Δt) of the gas. Thomas showed that the mass flowrate (M) of the gas was.

Thermal mass flow meters are often used in monitoring or controlling mass-related processes such as chemical reactions that depend on the relative masses of unreacted ingredients. In detecting the mass flow of compressible vapors and gases, the measurement is unaffected by changes in pressure and/or temperature.

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

Thermal flow measuring principle This measuring principle is based on the fact that heat is drawn from a heated body when a fluid flows past. A thermal 

Pulsed surface arc discharge (PSAD) is one of the essential techniques in flow control. In this paper, the effects of electrode configuration on heat transfer characteristics of PSAD and disturbance characteristics of PSAD on the flow field were investigated by thermal imaging technology and high-speed photography technology.

Liquid ingress causes thermal mass flow electronics to fry · Alicat DP instruments don't rely on heat · Contact · What's New? · About Us.

Gas mass flowmeters and controllers (thermal dispersion) are very accurate, because they have no moving parts and measure the mass of gas not volume. They are ideal for chemical line monitoring, purging instrument air lines, and filtration leading. Our gas mass flowmeters can handle a wide range of gases including nitrogen, oxygen and argon.

Mass flow controllers with the highest accuracy and long-term stability for a large dynamic range of measurements. Benefits Whatever you need a mass flow controller for, whether for devices, machines or processes: thanks to many years of experience in industrial automation and medical technology, Sensirion can provide you with the best possible support.

Series 200 Mass Flow Controllers (Analog) Model 201 Flow control from 5 sccm to 10 slpm 24 Model 202 Flow control from 10 slpm to 100 slpm 24 Mass flow measurement relates to the amount of heat absorbed by the process gas. The amount of heat the gas absorbs is determined by the gas molecular structure. Specific heat, the amount of heat
