3 Functions and features
The unit monitors liquids�
It detects the 3 process categories volumetric flow, consumed quantity, medium
temperature�
Application area
Conductive liquids with the following properties:
• conductivity:≥20µS/cm
• viscosity: < 70 mm2/s at 40 °C
4 Function
4.1 Processing of the measured signals
• The unit displays the current process values�
• It generates 2 output signals according to the parameter setting�
OUT1: 3 selection options ���������������������������������������������������������� parameter setting
switching signal for volumetric flow limit values ���������������������������������������(→9.2.1)
or pulse sequence for totalising meter �����������������������������������������������������(→9.3.1)
or switching signal for preset counter ������������������������������������������������������(→9.3.2)
OUT2: 4 selection options
switching signal for volumetric flow limit value ����������������������������������������(→9.2.2)
or switching signal for temperature limit value �����������������������������������������(→9.4.1)
or analogue signal for volumetric flow �����������������������������������������������������(→9.2.3)
or analogue signal for temperature ����������������������������������������������������������(→9.4.2)
OUT2 (pin 2) cannot only be used as an output
but also as an input for an external reset signal: �������������������������������������(→9.3.5)
4.2 Volumetric flow monitoring
The medium flows through a magnetic field� It generates a signal voltage which is
directly proportional to the volumetric flow�
• 2 switching signals for volumetric flow limit values can be provided (output 1
andoutput2).Fortheswitchingfunctions→4.5.
• An analogue signal proportional to the volumetric flow (4���20 mA or 0���10 V)
canbeprovidedonoutput2.Fortheanaloguefunctions→4.6.
In addition to the flow velocity, the unit also detects the flow direction� The positive
flowdirectionismarkedontheunitbyanarrow(“flowdirection”→5.2).

6
• Flow = “flow direction”: process value and display positive�
• Flow against the “flow direction”: process value and display negative�
Only positive process values are processed for the signal output (limit values and
analogue values for volumetric flow)�
4.3 Consumed quantity monitoring (totalizer function)
The unit has an internal quantity meter which continuously totals the volumetric
flow� The sum corresponds to the current consumed quantity since the last reset�
• The meter totals with the correct sign�
Flow according to the flow direction marked by the arrow: meter totals�
Flow against the marked flow direction: meter subtracts�
Counting pulses are only provided as the sum increases� After subtraction (consumded
quantity decreases) pulses are not provided again before the consumded quantity has
exceeded the former maximum value�
V = volumetric flow quantity, Imp = output pulses
• The current meter count can be indicated�
• In addition the value before the last reset is stored� This value can also be
indicated�
The meter saves the totalled consumed quantity every 10 minutes� After a power failure
this value is available as the current meter count� If a time-controlled reset is set, the
elapsed time of the set reset interval is also stored� So the possible data loss can be
maximum 10 minutes�
The meter can be reset as follows:
• Manualreset(→9.3.3).
• Time-controlledautomaticreset(→9.3.3).
• Externalinputsignalonpin2(→9.3.5).

4.3.1 Consumed quantity monitoring with pulse output
Output1providesacountingpulseifthevaluesetin[ImPS]isreached(→9.3.1).
4.3.2 Consumed quantity monitoring with preset meter
2 types of monitoring are possible:
• Time-dependent quantity monitoring
- Settings: [ImPS] = quantity x, [ImPR] = [no], [rTO] = time t�
- If the quantity x is reached during the time t, output 1 switches and remains
switched until the meter is reset�
- If the quantity x has not been reached after the time t, the meter is automati-
cally reset and counting starts again; output 1 does not switch�
• Quantity monitoring not time-dependent
- Settings: [ImPS] = quantity x, [ImPR] = [no], [rTO] = [OFF]�
- If the quantity x is reached, output 1 switches and remains switched until the
meter is reset�
4.4 Monitoring of temperatures
• A switching signal for temperature limit values can be provided on output 2� For
theswitchingfunctions→4.5.
• An analogue signal proportional to the temperature (4���20 mA or 0���10 V) can
beprovidedonoutput2.Fortheanaloguefunctions→4.6.
4.5 Volumetric flow or temperature monitoring / switching
function
OUTx changes its switching state if it is above or below the set switching limits
(SPx, rPx)� The following switching functions can be selected:
• Hysteresis function / normally open: [OUx] = [Hno]�
• Hysteresis function / normally closed: [OUx] = [Hnc]�
First the set point (SPx) is set, then the reset point (rPx) at the requested
distance�
• Window function / normally open: [OUx] = [Fno]�
• Window function / normally closed: [OUx] = [Fnc]�
The width of the window can be set by means of the distance between SPx and
rPx� SPx = maximum value, rPx = minimum value�

8
1 2
HY = hysteresis; FE = window; examples for volumetric flow monitoring
When set to the window function the set and reset points have a fixed hysteresis of 0�25 %
of the final value of the measuring range� This keeps the switching state of the output stable
if the volumetric flow varies slightly�
4.6 Volumetric flow or temperature monitoring / analogue
function
• The analogue start point [ASP] determines at which measured value the output
signal is 4 mA or 0 V�
• The analogue end point [AEP] determines at which measured value the output
signal is 20 mA or 10 V�
• Minimum distance between [ASP] and [AEP] = 20 % of the final value of the
measuring range�

9
UK
Voltage output 0 ��� 10 V (example volumetric flow monitoring)
Factory setting Measuring range scaled
MEW = final value of the measuring range
In the set measuring range the output signal is between 0 and 10 V�
It is also indicated:
Volumetric flow above the measuring range: output signal > 10 V�
Current output 4 ��� 20 mA (example volumetric flow monitoring)
Factory setting Measuring range scaled
MEW = final value of the measuring range
In the set measuring range the output signal is between 4 and 20 mA�
It is also indicated:
Volumetric flow above the measuring range: output signal > 20 mA�

10
4.7 Start-up delay [dSt]
If the start-up delay is active ([dSt] > [0]), note: as soon as the volumetric flow
quantity exceeds 0�5 % of the final value of the measuring range (VMR), the fol-
lowing processes are carried out:
• The start-up delay is activated�
• Output 1 switches as programmed: ON for NO function, OFF for NC function�
• Output 2 switches when the flow is evaluated ([SEL2] = [FLOW]) as pro-
grammed: ON for NO function, OFF for NC function�
• [dSt] only has an effect on the switching signals for volumetric flow monitoring�
After the activation of the start-up delay there are 3 options:
• The volumetric flow quantity increases quickly and reaches the switch point /
goodrangewithindSt→outputsremainactive.
• The volumetric flow quantity increases slowly and does not reach the switch
point/goodrangewithindSt→outputsarereset.
• Thevolumetricflowquantityfallsbelow0.5%withindSt→outputsareimme-
diately reset; dSt is stopped�
