3 Functions and features

The unit monitors liquids�

It detects the 3 process categories volumetric flow, consumed quantity, medium

temperature�

Applications:

• Water

• Glycol solutions

• Oils(viscosity:viscosity:≤68cStat104°F/≤68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 flow rate is monitored by an ultrasonic meter, the measured signals by the

electronics�

• 2 switching signals for volumetric flow limit values can be provided (output 1

andoutput2).Fortheswitchingfunctions→4.5.

• An analogue signal proportional to the volumetric flow (4��20 mA or 0��10 V)

canbeprovidedonoutput2.Fortheanaloguefunctions→4.6.

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 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:

• Manualreset(→9.3.3).

• Time-controlledautomaticreset(→9.3.3).

• Externalinputsignalonpin2(→9.3.5)

4.3.1 Consumed quantity monitoring with pulse output

Output1providesacountingpulseifthevaluesetin[ImPS]isreached(→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

theswitchingfunctions→4.5.

• An analogue signal proportional to the temperature (4��20 mA or 0��10 V) can

beprovidedonoutput2.Fortheanaloguefunctions→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 (fig� 1): [OUx] = [Hno]�

• Hysteresis function / normally closed (fig� 1): [OUx] = [Hnc]�

First the set point (SPx) is set, then the reset point (rPx) at the requested

distance�

• Window function / normally open (fig� 2): [OUx] = [Fno]�

• Window function / normally closed (fig� 2): [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�

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�

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�

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 /

goodrangewithindSt→outputsremainactive.

• The volumetric flow quantity increases slowly and does not reach the switch

point/goodrangewithindSt→outputsarereset.

• Thevolumetricflowquantityfallsbelow0.5%withindSt→outputsareimme-

diately reset; dSt is stopped�
