Turbimax CUA262

Summary

Product identification

Product: CUA262 Flow assembly Purpose: For installation of the CUS52D turbidity sensor in process water skids and closed pipe systems. Manufacturer: Endress+Hauser Document: TI01152C/07/EN/02.19

Application

The CUA262 is designed for direct installation of the CUS52D turbidity sensor into stainless steel pipes. It is suitable for:

• Turbidity measurement at all process stages in water treatment skids.
• Turbidity measurement in closed stainless steel pipe systems.
• Turbidity monitoring in filter modules.

Benefits include direct process installation, no water loss, self-venting with vertical installation, and suitability for drinking water applications due to stainless steel material.

Function and system design

A complete measuring system comprises:

• Flow assembly Flowfit CUA262
• Sensor Turbimax CUS52D
• Transmitter (e.g., Liquiline CM442)
• Measuring cable

Installation

General Instructions

• The flow assembly should be installed vertically.
• Connect the inflow at the bottom end for upward flow in the pipe.
• Avoid buckles and loops in hose systems.
• Pay attention to sensor installation instructions regarding flow direction.

Wall Effects

Backscattering from the pipe wall can cause false measurements for turbidity values < 200 FNU.

• If wall effects occur, change the orientation of the sensor.
• Avoid sudden changes in cross-section; gradual changes should be located far from the sensor.
• Do not install the sensor directly downstream from a bend; position it as far as possible from the bend.
• For reflective materials like stainless steel, pipe diameter should be at least 100 mm (4 in). On-site adjustment of installation position is recommended.
• Stainless steel pipes with diameter > DN 300 exhibit minimal wall effects.

Mounting the flow assembly

1. Attach the flow assembly to the pipe as a weld-on element.
2. Install the assembly vertically.
3. Connect the inflow at the bottom end (upward flow).

Mounting the sensor

• Only insert turbidity sensors with a 2" clamp into the assembly.
• Install the sensor such that the optical windows are aligned against the direction of flow.
• Use the installation marking on the sensor for correct orientation.
