INSTALLING A MEASURING CELL IN A PIPING SYSTEM (IN-LINE) / (Continuation)
To assure a reliable measurement please observe the following:
• The optical windows must be clean!
• The formation of gas bubbles in the medium should be prevented to avoid false measurements!
• The emitter and the receiver must always be aligned with the horizontal axis of the pipe when installed horizontally in order to avoid
incorrect measurements due to deposits on the glass discs (see picture below)!

• Only a completely filled pipeline guarantees a correct measurement!
• It may be advisable to provide for back pressure by means of restriction, or to install a trap.
• Dried-on residues on the glass discs distort measurements, e.g. after an operating process was in standby.
• It is recommended to include straight pipe distances, upstream and downstream the measuring cell, of at least 3 to 5 times the diameter of
the pipe.
• When mounted in a trap, stop valves or/and drain valve should be installed for easy maintenance and removing the measuring cell.
• Use the supplied mounting kit (key tool and suction cup) in order to remove and install the glass discs. Observe torque! (Torque spanner
Turbiclick 5.7 optionally available, please contact us).
INSTALLING AND CONNECTING THE IMMERSION PROBE (CP2 or CP5)
Installing the immersion probe
The TURBISWITCH CP2 and CP5 transducers are designed as hanging probes or for use with an extension tube.
It can be installed in slurry tanks, basins or open wells.
The probe should be installed so that it can be easily removed for cleaning.
Gas bubbles cause false measurements!
The frequency of cleaning routines depends on operating conditions.
Do not scratch the optics when cleaning the sensors!
The following measuring ranges apply to the TURBISWITCH CP2 and CP5 transducers:
Minimum detectable turbidity in the LOW range: starts at roughly 100...300FAU
Maximum detectable turbidity in the HIGH range: approx. 30000FAU (corresponds to approx. 100g/l SiO₂)
Maximum detectable turbidity in the MEDIUM range: 10% of the HIGH range
Maximum detectable turbidity in the LOW range: 1% of the HIGH range
Installation of the immersion probe TURBISWITCH CP2 or CP5 variant ZK or Z0
CP2 PVC
CP5 PP
The Z0 version is supplied without fitting accessories.
The ZK version is supplied with an angle bracket and its cable gland.
Please note: Caution with powerful flow, turbulences the cable must not be
overstretched!
In such cases, a cable or a rod may be used to secure the sensor (fixed on to the
two holes in the base of the sensor).
M6 threads can be tapped into the holes if necessary.
