Installation 3. Installation 3.1 General Requirements Observe the following before installing a conductivity cell. Specific requirements for particular types of installation are given in Sections 3.3 and 3.4. • Do not remove the Teflon sheath on 1or 10 constant cells, as this will change the cell constant value. • Do not use the cell in solutions which can affect the fittings or the cell materials. If in doubt, contact Honeywell. • Avoid all chlorinated hydrocarbons. Titanium and PES (0.01 and 0.
Installation 3.3 In-Line Type Mounting In addition to the General Requirements outlined above, note the following with regard to insertion-type mounting: • Make certain the liquid head is above the cell location during measurement. A vertical insertion (from above) or a horizontal insertion can be used. • Allow at least one-half inch clearance beyond the end of the cell and 1/8 to 3/16 inch radius clearance to permit circulation of the solution.
Installation 3.5 Torque Recommendations For inserting a cell in metal fittings or bushings - 40 ft-lb maximum. For inserting a cell in plastic fittings or bushings - 10 ft-lb maximum. Always use pipe sealant (preferably Teflon tape). 3.6 Dimension Drawings 1 1/ 8" (38mm) Hexagon Flow Out 1 1/2" (38mm) 3/4" NPT (Female) 1 1/2" (38mm) Octagon 3/4" NPT (Male) IN CELL 1 1/2" (38mm) Flow Chamber Flow In 8 3/4" (222mm) 14 1/2" max (368mm) 3/4" Fitting Allow 4 1/8" (105mm) for re moval of cell Notes: 1.

Electrical Connections 4. Electrical Connections 4.1 Overview The terminal board connections for the various Honeywell measuring instruments are given in the appropriate Figures in this section. To avoid the possibility of AC pickup in the cell leads, separate them from all AC line-voltage wiring or run them in a separate grounded conduit. ATTENTION Do not use shielded cable except where shown in the following figures. 4.2 Instrument Wiring for 4973 Cells with Integral Cable 4.2.

FOR PURE WATER SAMPLES IN NON-CONDUCTIVE (PLASTIC, GLASS, ETC.) PIPING, GROUND THE BLACK CELL ELECTRODE LEAD NEAR THE CELL. ALTERNATIVELY, CONNECT TO THE UDA GROUND SCREW AS SHOWN DOTTED. DO NOT GROUND 10, 25, OR 50 CONSTANT CELLS. 6. FOR CELL LEADS BLACK AND WHITE, USE 16 TO 22 AWG CABLE, SHIELDED TWISTED PAIR, WITH 30 pF MAX.

Maintenance 5. Maintenance 5.1 Overview The only maintenance that may be required is occasional cleaning. When cleaning, avoid scratching electrode surfaces. Do not use a brush or pipe cleaner. 5.2 To Clean the Cell The cell will require cleaning if sludge, slime, etc., accumulate in the flow channels. Since the materials of construction are chemically inert, chemical agents may be used and are recommended for cleaning the cells.
Maintenance 5.5 Air Entrapped in Cell Flow Channel If measurement errors appear for horizontal mountings of a 1 or 10 constant cell, it may be that air is entrapped in the cell flow channel. Take one of the following actions to eliminate this problem: 16 • Increase flow to at least 1 gpm. • Rotate the cell mounting so that its flow channel faces the same direction as the pipeline flow exit. • Install the cell and/or flow chamber vertically.
