Yokogawa Flow Fitting FF40-S22
Model FF40/FS40 flow fittings and subassemblies for conductivity measuring loops
To install SC42 conductivity sensors in a permanent or semi-permanentlocation Yokogawa can supply a range of flow and immersion fittings
A high degree of standardisation simplifies mounting, servicing and removal or replacement of the sensors.
The program includes flow fittings and their subassemblies for in-line or direct mounting of conductivity sensors in piping systems.
A wide choice of construction materials gives the user the best solution for any process considering chemical resistance, pressure and temperature specifications Refer figure 10.
Features
Yokogawa Flow Fitting FF40-S22
• Wide choice of construction materials.
• High degree of standardisation for all cells.
• Easy mounting, service and removal of sensors.
• Electrolitically polished stainless steel designs for optimal
corrosion resistance.
• Available with flange adapters.
A. Flow Fittings
Yokogawa Flow Fitting FF40-S22
From a practical point of view, the best mounting place for
conductivity sensor is in a by-pass with a sample valve. For these applications the flow fittings / subassemblies are ideal.
Features
• Easy mounting and maintenance of the sensors.
• Changeable liquid outlet position (right or left).
• Wall mounting bracket.
• Blanking plug for mounting and test applications.

B. Subassemblies
The subassemblies are designed for mounting conductivity sensors in a tank wall or directly into a piping system.
They can be easily mounted in the process piping by welding, cementing or screwing.
The stainless steel subassemblies meet the requirements of
DIN 11850 and DIN 11851 for sanitary constructions.
Features
• Suitable for mounting in a T-piece or directly in the piping system.
• Designs for mounting the plug-in type sensor and the insertion type sensor with collar piece DN 25 (D-model).
