OPERATION OF THE
MICRO
BUBBLE GENERATOR
APPLICATION NOTE PIV-028 (US)
Introduction
The Model BG-1000 (or BG-1000E) was designed to be simple to use
as seed particle generator for wind tunnel applications. The
operation for the generator can be summarized in eight simple steps.
Follow the steps and the generator can be ready for your
measurement in five minutes.
1. Remove the BG-1000 generator from the crate.
2. Fill the tank with water/soap solution.
3. Plug in the power cord.
4. Prime the pump.
5. Purge the nozzles.
6. Attach compressed air line.
7. Attach flexible feed hose.
8. Generator is ready to use.
All the controls for the generator are located on the front panel
for easy access:
•Pump Power
•Air Ball Valve
•Air Regulator
•Air Needle Valve
Filling the Tank with the Distilled Water/Soap Solution
The recommended water/soap mixture is with 10% soap by volume. For example, when using 19 liter of
distilled water, add 1.9 liter of soap detergent. As for the type of detergent, dish detergent without any dye or
scent, and not High Efficiency (HE) type is suggested. Such volume ratio provides the highest amount of micro
bubbles generated.

Prime the Pump
Open the cabinet door on the side and verify the valve is closed as indicated in the picture below. Turn the
black knob to allow water to flow through the pump and leave the pump running for about 10 seconds. The
pump is now primed.
Purge the Air from the Nozzles
Open the top of the tank to expose the nozzle cluster
inside the tank. Open the valve of the side of the
cluster and turn on the pump for about 10 seconds,
to allow water/soap solution to spray out of the top
nozzle hole. Turn off the pump and then shut off the
valve on the side.
Compressed Air Line and Flexible
Hose Connections
Connect the compressed air line on the back unit as
indicated in the picture. Connect also the flexible
hose on the top of the tank. There is a hose clamp to
allow the hose to be tightly secured.
Generator Ready to Generate the Micro Bubbles
Turn on the Pump Switch and open the Air Ball Valve, Use the Air Regulator and Air Valve to control the flow
rate of the bubble output. The mean size of the micro bubbles is about 15 microns.
Draining the BG-1000 Tank
When the measurement is completed, it is always recommended to drain the water/soap solution if the
generator is not to be used for a long period of time (say a couple of weeks). To drain the solution out, attach
a hose to the drain connection on the back of the BG-1000 and open the Yellow drain valve inside.
