MASS-VIEW Mass Flow Regulator with Display for Helium ( 0.2 .. 20 ln/min )
The MASS-VIEW®series operate on the principle of direct thermal mass flow measurement. A major advantage of using this type of sensor is that the instruments measure direct mass flow, without the need for temperature and pressure correction.
