1 1. INTRODUCTION 1-1. General The flow fittings (Model FF20) and their subassemblies (Model FS20) are used to mount sensor tips in a piping system so that the pH and/or the ORP (Redox) potential of the liquid flowing through it can be measured. The flow fittings are for connection between two pipes of the piping system providing a “flow through” path. From a practical plant aspect (for easy maintenance and calibration) the mounting place is in a by-pass behind a sample valve.

8 3. PIPING AND INSTALLATION 3-1. General It is important that, whatever method of mounting is used, the point of measurment is truly representative of the entrie solution. Avoid an area where the measurement varies significantly or the flow can be interrupted (the sensors must always be immersed in the process liquid). The recommended type of fitting or subassembly will depend on pressure, 12B6K1-40 MOUNTING A temperature, kind of liquid, pollution, etc.

Installation 3-3-1. Mounting the fitting Install the fitting at a convenient location for maintenance and calibration. Ensure that there is some place at the top of the fitting (approx.
10 3-3-2. Mounting the subassembly The subassembly can be cemented or welded directly in a piping system or in a T-piece of it. Install the subassembly at a convenient location for maintenance and calibration. Ensure that there is some place at the top of the fitting (approx. 20 cm) for mounting or replacing electrodes. Fig. 3-6 shows some mounting examples. Select the mounting position so that the sensors are immersed in the process liquid during measurement. (Model WU20) should be used (see fig. 3-7).
11 3-4-2. Mounting in a 1-hole design Unscrew the electrode mounting set and fix the cable and electrode as shown in fig. 3-8. 3-4-3. Mounting in a 3- and 4-hole design Unscrew the nut from the top end of the fitting or subassembly. Fix the electrodes and cables as shown in fig. 3-9. Note: In the holes for placing the electrodes are blanking plugs (stoppers). These plugs can be placed in unused holes after pushing the two O-rings over the bottom end.

M ounting kit for refillable ref. electrodes This mounting kit replaces the standard electrode mouting set so that elctrodes of Yokogawa with a long glass shaft can be fixed in the fitting or subassembly (see fig. 4-3). This mounting kit may be used as process pressure up to 3 bar. Higher pressure ratings require the standard mounting set for electrodes with DIN dimensions or, alternately a salt bridge (see §4-5).

18 ATTENTION Avoid using non-polar solvents like tri-chloro ethylene, toluene or hexane. Even cleaning with ethanol or acetone is not recommended. These solvents will break up the gel-layer on the glass bulb and afterwards needs to remain soaked in water for at least 12 hours before functioning normal. The PTFE diaphragm of the combined electrode can sometimes be regenerated by putting it in hot (60 to 80 °C) 1 molar Potassium chloride (KCl) solution and letting it cool to room temperature.
