Full Scale Flow - The Full Scale Flow Rate must be entered in Standard Cubic Feet per Hour (SCFH).
Upstream Pressure - Enter the expected pressure upstream of the valve. It must be entered in Pounds per Square Inch Atmosphere (PSIA): PSIG + 14.7.
Downstream Pressure - Enter the expected pressure downstream of the valve. It must be entered in Pounds per Square Inch Atmosphere (PSIA): PSIG + 14.7.
Specific Gravity - Enter specific gravity of gas. List of common gases.
Flowing Temperature - The flowing temperature must be entered in Deg. F. Deg F. = Deg. C * 1.8 + 32.
