Submersion Mounting
Most applications for D.O. monitoring are done using a submersible sensor.
Optical oxygen sensor can be used in stagnant water conditions, as they do not
need sample flow for measurement. Most aeration tank applications in
wastewater treatment plants can for biologically active coatings on the face of the
sensor, resulting in low readings. ATI’s Auto-Clean version of this product is
preferred in these applications. Submersible sensors are mounted to a 1" pipe
using a special sensor adapter that screws to the top of the sensor. The
mounting pipe can be secured to standard 1½” or 2” pipe rail using a mounting
bracket kit available from ATI (part number 00-0624) as shown in Figure 8.
For standard applications, the air line fitting may be removed as it is used only for
Auto-Clean installations.
