Signet 4150 Stilling Chamber with automatic air release valve
3-4150.096 Rev C 09/13 English
*3-4150.096*
Description
The Signet 4150 Stilling Chamber is used to remove air bubbles
from the fl ow stream before it passes through the measuring
cell of the Turbidimeter. Air bubbles will cause unstable or
incorrect readings if not eliminated from the fl ow stream.
The stilling chamber is a cylinder approximately 5 cm x 66 cm
(2 in. x 26 in.). Water enters the chamber via the outlet fi tting
near the top of the cylinder (see fi gure 1). As it passes through
the chamber, the fl ow velocity is reduced by the larger volume
of the chamber. This allows time for any entrained air to rise to
the top of the cylinder, where the automatic air vent releases it
into the environment.
For proper operation the stilling chamber must be mounted
lower than the sensor. For optimum results there should be at
least 76 cm (30 in.) as measured from midpoint of the air vent
to the inlet at the sensor.
The air vent has a maximum working pressure of 6 bar (90 psi)
and maximum temperature range to 106 °C (225 °F).
