Introduction 1. Introduction 1.1 Overview The 4909 Conductivity Cell Insertion/Removal Assembly is designed for use in a pipeline or closed vessel where it is desirable to remove the cell for inspection and maintenance without shutting down the system and releasing the pressure. The assembly comprises a 4908 Conductivity Cell and a 31074357 Removal Device which are shown assembled in Figs. 1-2 and 1-3. It is to be used in applications for which maximum pressure does not exceed 125 psig, and ca

Installation 3. Installation 3.1 Requirements To insure that a representative sample is being measured at all times, the solution must move through and completely purge out the cell channels or guard tube. If the measurement is made in a rapidly moving liquid, the existing circulation of the solution can be utilized by mounting the assembly as described in the next section so that the flow of the solution forces liquid through the cell. However, when measurements are to be made in quiescent so

4909 CPVC Conductivity Cell Insertion/Removal Assembly Operations Manual Allow at least 1/2 inch clearance beyond the end of the cell and 1/8 to 3/16 inch radius clearance surrounding the cell to permit circulation of the solution. Avoid locations where excessive temperature changes may occur. Allow clearance behind the support grip to permit removal of the cell per dimensions in Fig. 3-1 or 3-2. Locate the insertion/removal assembly on the pressure side of pumps; not the vacuum side. Avoid loc
