HF scientific Stilling Chamber - Manual (Page 3)

passes through the stilling chamber, its velocity becomes very low due to
the large diameter of the stilling chamber. This permits the fine air bubbles
in the liquid to rise to the top of the stilling chamber.
The automatic air vent in the top of the stilling chamber removes the air as
it collects at the top of the stilling chamber.
The stilling chamber should be located in the line before the liquid reaches
the sensor. The outlet from the stilling chamber should be run vertically at
least 30” (75cm) above the top of the automatic air release before being led
to the sensor.
The BRAUKMANN Automatic Air Vent has a maximum working pressure of
90 psi and maximum temperature range to 225°F (106° C). It is designed
for use on all types of hot water radiators, convectors, base board
convectors, heating units, venting pipes and fittings.
OPERATING INSTRUCTIONS
1. Before filling the system, make sure the red vent cap is securely
tight and that the valve is in the closed position (see figure 2) by
turning vent body clockwise. Use hands only to avoid damaging
the vent.
2. With the valve in the closed position, flush the system as required
to remove dirt, debris and contaminates.
3. Fill the system with the appropriate solution.
4. Start operation by turning the air vent body counter-clockwise to
the open position (see figure 2).
