3.8 The controlling of pressure and temperature, flow showing
Pressure control
• uses micrometer valve to control and ensure stable pressure for extraction and separation
• Uses Y-160 piezometer to show pressure
Temperature control
• Uses digital meter to show and control precision
Flow display
• CO2 uses metal rotor flow meter, range is 0～150 ㎏/H
• Additive meter uses glass rotor flow meter, rang is 0~20Kg/H

3.9 Safety system
• The pressure pump has a safety limit pressure control, so if the operating pressure is exceeded the safety control will activate and stop the pump.
