CAUTION
SENSOR/PROCESS APPLICATION COMPATIBILITY
The wetted sensor materials may not be compatible with process com position and operating conditions.
Application compat ibility is entirely the responsibility of the user.
WARNING
Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and the process
temperature is lowered to a safe level!

Installation
Depending on the option selected, the sensor can be installed in either a 1 ½-inch or 2-inch Tri-Clamp tee. The gasket,
clamp, and tee must be supplied by the user. The electrodes must be completely submerged in the process liquid, i.e., up
to the inside surface of the flange.
If the sensor is installed in a side stream with the sample draining to open atmosphere, bubbles may accumulate on the
electrodes. Trapped bubbles will cause errors. Normally, as bubbles accumulate the conductivity reading drifts down. To
control bubble formation, apply a small amount of back pressure to the sensor.
