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.
BEFORE REMOVING THE SENSOR, be
absolutely certain the process pressure is
reduced to 0 psig and the process tempera-
ture is at a safe level!

Summary
Keep 1/4 inch (6 mm) clearance between electrodesand piping. The electrodes must be completely sub-merged in the process liquid, i.e., to the level of thethreaded connection. See Figure 1 for recommendedorientation. If the sensor is installed in a side stream with thesample draining to open atmosphe...
