5 Operation
Before switching on the power, be sure that:
System is checked for leakage of gases and liquids
All connections have been made
Flow-set points are zero
No liquid has been spilled into the equipment
Switch on and then:
Allow 30 minutes (from switching on) to warm up (common for thermal flow controllers)
Wait until pre-set temperatures are reached. When the LED indicators turn blue,
temperatures are reached.
Make sure that the carrier gas is always flowing before the liquid flow setpoint is applied.

Especially for tracing, the temperature is only controlled at a single location, while inadequate insulation may
introduce cold-spots at which condensation may occur.
5.2.4
Temperature and flow setpoint
5.3 Operating settings
Make sure that the tracing and heating temperatures are well above the dew point of the desired vapor flow at the process
conditions.
Be aware that the temperatures (both heater and tracing) depend on the location of the sensor. Therefore, it is advised to set the
heater temperature approximately 20°C above the theoretical temperature.
In addition, it is advised to set the tracing temperature another 10°C higher.

Properties. Visit www.fluidat.com
Assumptions: Consider water vapor as an ideal gas, 1 mole of ideal gas at normal
conditions = 22.4 l, 1 mole of water is 18 g and 1 hour is 60 min.
1 atm. = 1013.25 mbar.
The MoleRatio:
So in a gas flow of 2 ln/min, the saturated vapor flow (100% r.h.) is:
[ln/min]
and in [g/h]:
[g/h]
The MoleRatio:
so in a gas flow of 2 ln/min, the saturated vapor flow (50% r.h.) is:
and in [g/h]
[g/h]
Result: at 50% r.h., the water flow is 29.41 g/h.
5.3.1 Operation example
Application
The Vapor Delivery Module can be used for generating certain humidity in a gas stream. Carrier gas and liquid (water) are
controlled to regulate the humidity. The water is mixed with the gas and consequently evaporated. The humidity at a certain
temperature corresponds with a certain ratio of gas and water, this ratio can be set by the flow controllers which are part of the
Vapor Delivery module.
Calculation example for setting of relative humidity
At atmospheric pressure, at 80°C, 2 ln/min Air has to be moistened. Which water flow is needed for a r.h. of 50%. The vapor
pressure of water at 80°C is 473.3 mbar according to FLUIDAT®.
At 100% r.h., the (Mole)Ratio between gas and water is:
At 50% r.h., the (Mole)Ratio between gas and water:
