2 Safety instructions

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

service life�

mental conditions without any restrictions�

• Only use the product for its intended purpose (→ 3 Functions and features)�

• Only use the product for permissible media (→ 12 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 liquids and gases�

It detects the process categories flow and medium temperature�

Application area

• Air

• Water

• Glycol solutions (reference medium: 35 % ethylene glycol solution)

• Low-viscosity oils (viscosity: ≤ 40 mm²/s at 40 °C / ≤ 40 cSt at 104 °F)

• High-viscosity oils (viscosity: ≥ 40 mm²/s at 40 °C / ≥ 40 cSt at 104 °F)

Selection of the medium to be monitored → 10.4.3�

This is a class A product�

The unit may cause radio interference in domestic areas�

►If required, take appropriate EMC screening measures�

4 Function

• The unit detects flow based on the calorimetric measuring principle�

• The unit also detects the medium temperature�

• It features an IO-Link interface�

• The unit displays the current process value�

It generates 2 output signals according to the parameter setting:

OUT1/IO-Link: 2 selection options Parameter setting

- Switching signal for flow limit values → 10.2.3

- Frequency signal for flow → 10.2.5

OUT2: 7 selection options Parameter setting

- Switching signal for flow limit values → 10.2.4

- Switching signal for temperature limit values → 10.3.1

- Analogue signal for flow → 10.2.7

- Analogue signal for temperature → 10.3.3

- Frequency signal for flow → 10.2.6

- Frequency signal for temperature → 10.3.2

- Input for external teach signal → 10.2.9

4.1 Operating modes (ModE)

The unit provides three selectable operating modes for flow measurement:

Operating

mode

Medium Display unit

REL Liquids, air % (of the taught range) → 10.2.8

LIQU Liquids m/s, l/min, m3/h (fps, gpm, cfm)

GAS Air m/s, l/min, m3/h (fps, gpm, cfm)

The selected operating mode has no effect on the temperature measure-

ment, only absolute values in °C or °F are indicated.

The parameter settings are saved in the respective operating mode, i�e�

when the operating mode is changed, the settings are not lost�

If the operating modes LIQU and GAS are selected:

►Define the medium and the internal pipe diameter (→ 10.2.1)�

►If required, calibrate curve of measured values (→ 10.4.9)�

4.2 Select the medium (MEdI)

The unit has characteristic curves for different media� Depending on the operating

mode, the following media can be selected in the menu (→ 10.4.3):

Operating mode

Medium REL LIQU GAS

*OIL1:

viscosity ≥ 40 mm²/s at 40 °C / ≥ 40 cSt at 104 °F

**OIL2:

viscosity ≤ 40 mm²/s at 40 °C / ≤ 40 cSt at 104 °F

H2O x x

OIL1* x x

OIL2** x x

GLYC x x

AIR x x

4.3 Define the internal pipe diameter (diA)

In the operating modes LIQU and GAS the internal pipe diameter has to be en-

tered to define the volumetric flow (→ 10.2.2)

�

4.4 Customer-specific calibration (CGA)

Via the calibration factor CGA the sensor can be adjusted to a reference flow in

the application�

The customer-specific calibration allows changing the gradient of the curve of

measured values� It influences the display and the outputs�

140 % ME

100 % ME

60 % MEW

MEWQ

AV1

A = Operating value for display and

output signals

Q = Flow

MEW = Final value of the measuring

range

V0 = Curve of measured values at

factory setting

V1,

= Curve of measured values after

calibration

The change in the gradient is indicated in percentage�

Factory setting: CGA = 100 %�

After a change the calibration can be reset to factory setting (→ 10.5.2)�

Depending on the set CGA factor, it may not be possible to use the com-

plete measuring range�

4.5 Switching function

OUTx changes its switching status if it is above or below the set switching limits

(flow or temperature)� Hysteresis or window function can be selected� Example of

flow monitoring:

Hysteresis function Window function

rP FL

SP = set point

rP = reset point

HY = hysteresis

Hno = hysteresis NO (normally open)

Hnc = hysteresis NC (normally closed)

FH = upper limit value

FL = lower limit value

FE = window

Fno = window NO (normally open)

Fnc = window NC (normally closed)

When the hysteresis function is set, the set point SP and the reset point rP

are defined� The rP value must be lower than the SP value� The distance

between SP and rP is at least 4 % of the final value of the measuring range

(= hysteresis)�

If only the set point is changed, the reset point is changed automatically;

the difference remains constant�

When set to the window function the upper limit value FH and the lower lim-

it value FL are defined� The distance between FH and FL is at least 4 % of

the final value of the measuring range�FH and FL have a fixed hysteresis of

0�25 % of the final value of the measuring range� This keeps the switching

status of the output stable if the flow rate varies slightly�

4.6 Analogue function

The unit provides an analogue signal that is proportional to the flow quantity or the

medium temperature�

Within the measuring range the analogue signal is 4��20 mA�

The measuring range is scalable:

• [ASP2] determines at which measured value the output signal is 4 mA�

• [AEP2] determines at which measured value the output signal is 20 mA�

Minimum distance between [ASP2] and [AEP2] = 20 % of the final value of

the measuring range�

For flow measurement in the operating mode [ModE] = REL, [ASP2] and

[AEP2] are not available� In this operating mode, the characteristic curve of

the analogue output is defined by the flow adjustment:

high flow = 20 mA; low flow = 4 mA�

If the measured value is outside the measuring range or in the event of an internal

error, the current signals indicated in figure 1 are provided�

For measured values outside the display range or in case of a fault, messages are

displayed (UL, OL, Err; → 13)�

The analogue signal in case of a fault is adjustable (→ 10.4.8):

• [FOU] = On determines that the analogue signal goes to the upper final value

(22 mA) in case of an error�

• [FOU] = OFF determines that the analogue signal goes to the lower final value

(3�5 mA) in case of an error�
