Turbimax CUS52D	Product description

3Product description

3.1Product design

The sensor with the 40 mm (1.57 in) diameter can be operated directly and completely in the process without the need for further sampling (in-situ).

The sensor includes all necessary modules:

•Power supply

•Light sources

•Detectors

Detectors record the measuring signals, digitize them and process them into a measured value.

•Sensor microcontroller

This is responsible for controlling internal processes and transmitting data.

All data - including the calibration data - are stored in the sensor. The sensor can be precalibrated and used at a measuring point, calibrated externally, or used for several measuring points with different calibrations.

3.1.1Measuring principle

The sensor works using the 90° light scattering principle in accordance with ISO 7027 and meets all the requirements of this standard (no divergence and a maximum convergence of 1.5°). The ISO 7027 standard is obligatory for turbidity measurements in the drinking water sector.

90° ± 2.5°

20° - 30°

8 Permitted and unacceptable orientations in pipes

•Install the sensor in places with consistent flow conditions.

•The best installation location is in the ascending pipe (item 1). Installation in the horizontal pipe (item 4) is also possible.

•Do not install the sensor in places where air spaces or bubbles occur (item 3) or where sedimentation may occur (item 2).

•Avoid installation in the down pipe (item 5).

•Avoid fittings downstream from pressure reduction stages which can lead to outgassing.

Wall effects

Backscattering on the pipe wall may result in the distortion of measured values in the case of turbidity values < 200 FNU. Therefore a pipeline diameter of at least 100 mm (3.9 in) is recommended for reflecting materials (e.g. stainless steel). An assembly adjustment onsite is also recommended.

Endress+Hauser

13

Installation	Turbimax CUS52D

Pipes made of stainless steel with diameter >DN 300 exhibit hardly any wall effects.

Black plastic pipes with diameter > DN 60 exhibit hardly any wall effects (<0.05 FNU). For this reason, the use of black plastic pipes is recommended.

9 Orientations for pipes and assemblies

•Install the sensor in such a way that the light beam is not reflected → 9, 14 (item 6).

•Avoid sudden changes in cross-section (item 9). Changes in cross-section should be gradual and located as far away as possible from the sensor (item 10).

•Do not install the sensor directly downstream from a bend (item 7). Instead position it as far away as possible from the bend (item 8).
