| Parameters after change: | |
| Comments: | The MFC for the bypass ( 179327) had a sensor downstream of the valve. Parameters before change: - Control: 7.33 LPM Vol Flow - Vol Flow = 7.33 LPM - Mass FLow = 6.07 SLPM - pressure = 848mBarA I have swapped it for one with the sensor upstream ( 179324), making the measured volumetric flow more representative of VSCC flow (measured at same pressure). Parameters after change: - Control: 7.33 LPM Vol Flow - Vol Flow = 7.33 LPM - Mass FLow = 7.07 SLPM - Pressure = 987 mBarA Better for the VSCC |
