MODEL 430 DO SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
1.3 AVAILABLE MODELS
The Model 430-01 and -02 Sensor is a flow through
assembly. The sensor is supplied in a 1-1/2 inch PVC
tee for installation into a process line.
The Model 430-03 Submersible Sensor is for use in
those applications where the required flow velocity can
be maintained without the use of an agitator. When the
measurement is being made in a stagnant pond or
other media where the minimum flow rate of 1.5 FPS
cannot be obtained, the Model 430-04 must be select-
ed. This model is designed for submersible use and is
provided with its own agitator to ensure adequate flow
velocity at the membrane.
The Models 430-03 and 04 may be provided with an
optional mounting bracket assembly. This bracket is
constructed of light weight aluminum and can be
adjusted to satisfy virtually any aeration basin mount-
ing requirement. Once installed, the probe can be
removed without the use of tools. A single locking pin
holds the assembly rigidly in place but allows it to be
easily removed for inspection or cleaning.
