The filling balance weight (or nozzle lift) refers to the amount of 
weight the balloon is capable of lifting when filled. In other words, it 
is the amount of weight that needs to be loaded during balloon filling 
(FB13 nozzle and weights). 

Filling the Balloon 

NOTE 

Check visually that all of the balloons to be filled are structurally 
sound and have no perforations or other apparent defects in the nozzle 
section. 

 

To fill the balloon, do the following: 

1. 

Connect the side tube of the filling balance to the pressure 
reducing valve on the gas cylinder (or hydrogen generator) with 
a flexible plastic hose. 

2. 

Select the nozzle which best fits into the neck of the balloon to 
be used. 

3. 

Load the additional weights that are needed to obtain the 
required lift. 

4. 

Secure the neck of the balloon to the balance nozzle with a 
clamp. Look out for sharp objects near the filling balance so that 
no damage is caused to the relaxed balloon when it rests on its 
bed. 

5. 

Turn on the gas from the pressure reducing valve. Let the gas 
flow slowly into the balloon. 

6. 

When the balloon is sufficiently filled, i.e. the balloon just raises 
the balance, turn off the gas and tie the neck of the balloon 
above the balance nozzle with approximately 0.5 m (2 ft) bit of 
string. Remove the balloon from the nozzle. 

NOTE 

While the balloon filling instructions in this manual are based on 
Totex balloons, they can also be applied when other meteorological 
balloons are being used.
