Technical Information
Flowfit CCA151
Flow assembly for disinfection sensors CCS5xD
Simple assembly for measuring disinfection in
drinking and process water
Application
• Drinking water
• Utilities in all sectors
• Applications with low sample volumes
Your benefits
• Suitable for all disinfection processes without pH compensation - chlorine dioxide
and others
• Requires only low sample flow: At least 5 l/h (1.32 gal/h)
• A new addition to the flow assembly range: Same form as and can be exchanged
for CCA250

Mode of operation
Measuring system
You can carry out reliable chlorine dioxide measurements using suitable sensors with flow assembly
CCA151 . You can remove, clean, sterilize or calibrate/adjust the sensors without interrupting the
process.
The assembly can be installed in both vessels and pipes.
A complete measuring system comprises:
• Disinfection sensor CCS50D (membrane-covered, ⌀25 mm) with corresponding installation
adapter
• Flowfit CCA151 flow assembly
• Measuring cable CYK10
• Transmitter, e.g. Liquiline CM44x or CM44xR
• Optional: Extension cable CYK11

Installation
Orientation
Installation instructions
The assembly is designed for installation on panels, walls or level surfaces. G 1/8" connections and a
hose connection with an external diameter of 6 mm and an internal diameter of 4 mm are provided
for this purpose.
The assembly is designed in such a way that it must be installed vertically.
The sensor that is used can restrict the orientation.
WARNING
L
Risk of injury from high pressure, high temperature or chemical hazards if process medium
escapes.
Wear protective gloves, protective goggles and protective clothing.
‣
Mount the assembly only if vessels or pipes are empty and unpressurized.
‣
Prior to installation, check the flange seal between the flanges.
1. Mount assembly on vertical surface.
2. Connect to the vessel or pipe via the process connection.
Bypass operation
To achieve flow through the assembly with a bypass, pressure p1 must be higher than pressure p2.
This requires the installation of an orifice plate or throttle valve in the main pipe.
p1 must not exceed the permitted operating pressure for the assembly of 4 bar (58 psi).
If the sensor is installed, the sensor's pressure specifications must also be observed.
1. Mount the assembly vertically.
2. Connect the medium using the usual commercial connection fittings. Depending on
requirements, use the usual sealing materials, e.g. PMMA-compatible thread adhesive, Teflon
tape or O-ring made of FKM.
3. Installing the assembly in the bypass is preferable to installing it directly in the process line.
The bypass line can be blocked off without interrupting the process (a shut-off valve is required
upstream and downstream). This allows, for example, the sensor to be cleaned without
restricting the process.
4. Install a dirt trap (filter) with a mesh size of 500 μm upstream from the assembly. If a
pressure-reducing valve is used, it usually includes a dirt trap.
5. Set flow value upstream from the assembly, e. g. by installation of a flow setting.
6. Install a DN5-8 tap downstream from the assembly outlet to allow samples to be taken for
reference measurements in accordance with the DPD method.

Open outlet operation
p must not exceed the permitted operating pressure for the assembly of 4 bar (58 psi).
If the sensor is installed, the sensor's pressure specifications must also be observed.
If the medium pressure is above 4 bar (58 psi), a pressure-reducing valve is required.
1. Mount the assembly vertically.
2. Connect the medium using the usual commercial connection fittings. Depending on
requirements, use the usual sealing materials, e.g. PMMA-compatible thread adhesive, Teflon
