- Page 15 Cleanfit CUA451 Installation 5.1.3 Installation instructions Installation location The assembly is designed for installation on vessels and pipes. Suitable nozzles must be available for this. The minimum pipe diameter is DN 80. ‣ Before mounting the sensor, mount the assembly on the vessel or in the pipe.
- Page 16 Installation Cleanfit CUA451 ‣ Make sure to avoid a siphon effect at the rinse chamber outlet. The inflow to the rinse chamber is always from below. Clearance between the sensor and pipe wall If the sensor is installed in pipes or very close to the wall, this can cause backscatter and therefore a higher sensor signal.
