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. They are supplied with a ring to
hold calibration dish for this cleaning and/or calibration.
The subassemblies should be cemented or welded direct in the piping system or in a
T-piece of it. The subassemblies of stainless steel meet the requirements of DIN 11850
for mounting in sanitary constructions.
1-2. Features
- Wide choice fo construction materials.
- High degree fo standardisation reduces spare holding requirements.
- Direct mounting of sensors with DIN dimensions.
- Liquid earth sensor for stable measurements.
- High pressure and temperature specifications.
- Chemical or brush cleaning (optional in 4-hole fittings).
2. UNPACKING AND CHECKING
2-1. Unpacking and inspection
When you receive the flow fitting (Model FF20) or the subassembly flow fitting (Model FS20)
it is packed in a cardboard box. Open the box and check that the model code is the same
as on the packing list (see §2-3 for the model code). Also check that it is supplied with the
options you ordered. These options are delivered in seperate bags.
If you have any problems or questions, please contact the nearest Yokogawa service
center or sales organisation for assistance.
2-2. Mounting location
The flow fitting or subassembly flow fitting is
intended to be used for pH and/or ORP
(Redox) measurement. The location should be
in a bypass of a piping system behind a
sample valve. The angle of the fitting with the
horizontal should be less than 15°
(see fig. 2-1).
The pressure and temperature ratings of the
electrode inside the fitting should be noticed to
determine the maximum rating of the
measurement point.
