2 Basic safety instructions

2.1 Requirements for personnel

• Installation, commissioning, operation and maintenance of the measuring system may be

carried out only by specially trained technical personnel.

• The technical personnel must be authorized by the plant operator to carry out the specified

activities.

• The electrical connection may be performed only by an electrical technician.

• The technical personnel must have read and understood these Operating Instructions and

must follow the instructions contained therein.

• Faults at the measuring point may only be rectified by authorized and specially trained

personnel.

Repairs not described in the Operating Instructions provided must be carried out only

directly at the manufacturer's site or by the service organization.

2.2 Designated use

CUS71D is a sensor designed for interface measurement in water and wastewater.

The sensor is particularly suited for use in the following applications:

• Wastewater treatment: primary clarifier, sludge thickener, secondary clarifier

• Water treatment: sedimentation tank after flocculant dosage, sludge height in contact

sludge processes

• Static separation processes: with/without slow stirring and without introduction of air

Use of the device for any purpose other than that described, poses a threat to the safety of

people and of the entire measuring system and is therefore not permitted.

The manufacturer is not liable for damage caused by improper or non-designated use.

NOTICE

Applications outside specifications!

Incorrect measurements, malfunctions and even measuring point failure could result

‣Use the product only in accordance with the specifications.

‣Pay attention to the technical data on the nameplate.

2.4 Operational safety

Before commissioning the entire measuring point:

1. Verify that all connections are correct.

2. Ensure that electrical cables and hose connections are undamaged.

3. Do not operate damaged products, and protect them against unintentional operation.

4. Label damaged products as defective.

During operation:

‣If faults cannot be rectified:

products must be taken out of service and protected against unintentional operation.

2.5 Product safety

The product is designed to meet state-of-the-art safety requirements, has been tested, and

left the factory in a condition in which it is safe to operate. The relevant regulations and

European standards have been observed.

2.6 IT security

We only provide a warranty if the device is installed and used as described in the Operating

Instructions. The device is equipped with security mechanisms to protect it against any

inadvertent changes to the device settings.

IT security measures in line with operators' security standards and designed to provide

additional protection for the device and device data transfer must be implemented by the

operators themselves.

Product description Turbimax CUS71D

3 Product description

3.1 Product design

The sensor is designed for continuous in-situ determination of interfaces.

The sensor includes all necessary modules:

• Power supply

• The ultrasonic source emits the measurement signals.

• The ultrasonic receiver receives the measurement signals, digitalizes the signals and

converts them to a measurement value.

• The sensor microcontroller controls the internal operations and data transmission.

The preconfigured sensor can be used at a measuring point.

3.1.1 Measuring principle

A piezoelectric crystal is enclosed in a flat cylindrical plastic housing. When the crystal is

excited by an electrical voltage, it generates a sonar signal. This causes ultrasonic waves to be

transmitted at a frequency of approx. 650 kHz and at an angle of 6° to scan the separation

zones.

The measured variable is the time the transmitted ultrasonic signal needs to reach the solid

particles in the separation zone and return to the receiver. The separation zone is computed

after the maximum slope and the maximum signal amplitude.

A sensor version featuring a wiper is available to reliably avoid the buildup of deposit on the

sensor membrane.
