TI062C/07/en/07.09 71099077 Technical Information Flowfit CCA250 Flow assembly for chlorine and pH/ORP sensors Application The flow assembly CCA250 has been specially designed to hold the chlorine resp. chlorine dioxide sensors CCS120, CCS140, CCS141, CCS240, CCS241 or CCS142D. Additionally there are two mounting positions for sensors with Pg 13.5 thread and 120 mm (4.72 inch) installation length, e.g. pH or ORP sensors. Main areas of application are:
- Drinking water
- W a s h w a t e r
- Process applications
- Swimming pool water Your benefits
- Needle valve to adjust the flow and flow meter for optical control
- Inductive proximity switch in combination with Liquisys M CCM223/253: a "Flow alarm" can be activated
- Potential matching pin for pH measurement
- Cap screwed from below allows calibration of the pH and ORP sensors without sensor removal

Installation instructions Bypass operation To achieve a flow through the bypass, pressure p1 has to be higher than pressure p2. Therefore, you have to install an orifice plate or a throttle valve in the main pipe (→ å, pos. 4). a0011520 Installation example with bypass and orifice plate in the main pipe
1 Stop valve (to be provided by customer)
2 Pressure reducer (if p1 > 4 bar (58 psi)) (to be provided by customer)
3 Stop valve (to be provided by customer)
4 Orifice plate in the main pipe (to be provided by customer)
Caution! p2 must not exceed the permissible operating pressure of the assembly of 4 bar (58 psi). Open outlet operation a0011521 Installation example with open outlet
