• Read this document before setting up the product and keep it during the entire

service life�

• The product must be suitable for the corresponding applications and environ-

mental conditions without any restrictions�

• Only use the product for its intended purpose (→ Functions and features).

• Only use the product for permissible media (→ Technical data).

• If the operating instructions or the technical data are not adhered to, personal

injury and/or damage to property may occur�

• The manufacturer assumes no liability or warranty for any consequences

caused by tampering with the product or incorrect use by the operator�

• Installation, electrical connection, set-up, operation and maintenance of the unit

must be carried out by qualified personnel authorised by the machine operator�

• Protect units and cables against damage�

3 Functions and features

The unit monitors liquid media� It detects the 2 process categories volumetric flow

and medium temperature�

Pressure Equipment Directive (PED)

The units comply with the Pressure Equipment Directive and are designed and

manufactured for group 2 fluids in accordance with the sound engineering prac-

tice� Use of group 1 fluids on request�

Application area

Conductive liquids with the following properties:

• Conductivity: ≥ 20 µS/cm

• Viscosity: < 70 mm2/s at 40 °C; < 70 cSt at 104 °F

4 Function

• The unit detects the flow based on the magnetic-inductive volumetric flow

measuring principle�

• The unit also detects the medium temperature�

• The unit displays the current process value�

4.1 Processing of the measured signals

The unit generates 2 output signals according to the parameter settings:

OUT1: Parameter setting

- Analogue signal for temperature → 10.2

OUT2: Parameter setting

- Analogue signal for volumetric flow quantity → 10.3

4.2 Direction of flow

In addition to the flow velocity and the volumetric flow quantity, the unit also

detects the direction of flow�

An arrow with the text "flow direction" on the unit indicates the positive flow

direction�

Flow... Process value display

corresponds to the marked flow direction + (positive)

against the marked flow direction - (negative)

Only positive process values are processed for the signal output�
