5.2 Volumetric flow direction

In addition to the flow velocity and the volumetric flow, the unit also detects the volumetric flow direction
5.2.1 Determining the volumetric flow direction [Fdir]

An arrow with the text “flow direction” on the unit indicates the positive flow direction The volumetric flow direction can be reversed ( 11.5.9)

Use the supplied label to mark the changed volumetric flow direction

(new positive flow direction)

5.2.2 Detection of the volumetric flow direction [dir.F] When [dirF] is activated ( 11.2.5), the volumetric flow direction is indicated by a switching signal
The output is switched on until the volumetric flow falls below the set minimum volumetric flow quantity in negative flow direction (- LFC)(1) Then the following applies:
– The output switches ON when volumetric flow is above + LFC (2)
– The output switches OFF when volumetric flow is below – LFC (3)

Positive volumetric flow direction = marked flow direction, with factory setting marked by the arrow on the unit or after change via [Fdir] marked by the supplied label ( 5.2.1)

5.3 Consumed quantity monitoring
The unit has three internal quantity meters (= totalisers) The totalisers continuously sum up the consumed quantity and provide three process values via the parameters [Vol1], [Vol2] and [VolL]:

Totaliser Vol1 Vol2 VolL

Process value totaliser 1 totaliser 2 lifetime totalisator (= meter reading over the whole lifetime)

Read access via IO-Link cyclical acyclical acyclical

The totalisers only sum up volumetric flow quantities above the LFC value 5.8 Low flow cut-off
The metering method of the totalisers Vol1 and Vol2 can be set so that volumetric flow values are either ignored, subtracted or totalled in negative volumetric flow direction ( 5.3.1) The metering method of VolL cannot be set It totals all volumetric flow quantities irrespective of the volumetric flow direction
The process values of the quantity meter (totaliser) can be displayed ( 11.3.8) or read via the IO-Link interface
Pulse signals (pulse output) or a switching signal (preset counter) can be used to monitor the consumed quantity 5.3.3 Consumed quantity monitoring via pulse signals 5.3.4 Consumed quantity monitoring via switching signal (preset counter)

5.3.1 Metering method of the quantity meters
The quantity meters take account of the volumetric flow direction when totalling the consumed quantity ( Fig. 2). The following metering methods can be defined via the parameters [FPro1] and [FPro2]:

[FPro1] Metering method [FPro2]*

0+

5.3.2 Meter reset There are different ways to reset the quantity meters 11.3.4 Manual meter reset 11.3.5 Time-controlled meter reset 11.3.7 Meter reset via external signal Meter reset via the IO-Link interface If the quantity meter is not reset by applying one of the above-mentioned methods, an automatic reset is made when the maximum volumetric flow quantity that can be displayed is exceeded (overflow)
UK
The total meter reading [VolL] cannot be reset
The meter saves the totalled volumetric flow quantity every 10 seconds After a power failure this value is available as the current meter reading If a time- controlled reset is set, the elapsed time of the set reset interval is also saved So the possible data loss is maximum 10 seconds
5.3.3 Consumed quantity monitoring via pulse signals Every time the volumetric flow quantity (pulse value) set under [ImPS] has been reached, the output provides a pulse signal The pulse signal consists of a short switching on and off of the output The switching status LEDs on the unit do not display the switching operation
Pulse signals are not available via the IO-Link interface

13

5.3.4 Consumed quantity monitoring via switching signal (preset counter)
When the volumetric flow quantity set under [ImPS] has been reached, the output provides a switching signal The output remains switched until the meter reset After a totaliser reset metering starts again

The accuracy of the consumed quantity measurement depends on the accuracy of the volumetric flow measurement

By setting [rTo1] it is set when the output switches and when the totaliser Vol1 is reset:

Within the measuring range the frequency signal is between 0 and 10 kHz
The frequency signal is scalable:
· [FrP1] defines the frequency signal in Hz that is provided when the upper measured value (MEW or FEP1) is reached

The measuring range is scalable:
· [FSP1] defines the lower measured value from which a frequency signal is provided Note: [FSP1] cannot be set for volumetric flow measurement
· [FEP1] defines the upper measured value at which the frequency signal FrP1 is provided Minimum difference between [FSP1] and [FEP1] = 20 % of the final value of the measuring range

5.6 Switching output
OUTx changes its switching status if it is above or below the set switching limits (flow velocity or volume flow or temperature) Hysteresis or window function can be selected Example of volumetric flow monitoring:

SP

FH

rP

FL

UK

Fig 5: hysteresis function
SP = set point rP = reset point HY = hysteresis Hno / Fno = NO (normally open)

Fig 6: window function
FH = upper limit FL = lower limit FE = window Hnc / Fnc = NC (normally closed)

When the hysteresis function is set, the set point (SP) is defined first and then the reset point (rP) which must have a lower value If only the set point is changed, the reset point is changed automatically; the difference remains constant

When the window function is set, the upper limit (FH) and the lower limit (FL) have a fixed hysteresis of 025 % of the final value of the measuring range This keeps the switching status of the output stable if the volumetric flow varies slightly

19

5.7 Measured value damping The damping time [dAP] enables setting after how many seconds the output signal has reached 63 % of the final value if the volumetric flow value changes suddenly The set damping time stabilises the switching outputs, the analogue outputs, the display and the process value transmission via the IO-Link interface The damping time is added to the response time of the sensor ( Technical data) The signals UL, crUL, OL and crOL ( ) are determined by taking the damping time into account
The damping time only has an effect on the volumetric flow measurement
5.8 Low flow cut-off With the function low flow cut-off [LFC] it is possible to suppress low volumetric flow values Volumetric flow below the LFC value is evaluated by the sensor as standstill (Q = 0)
5.9 Start-up delay
The start-up delay [dSt] influences the switching outputs of the volumetric flow monitoring
If the start-up delay is active ([dSt] > 0), the following applies: As soon as the volumetric flow quantity exceeds the LFC value ( 5.8), the following processes are carried out: > The start-up delay is activated > The outputs switch as programmed: ON for NO function, OFF for NC function After activation of the start-up delay there are 3 options: 1 The volumetric flow increases quickly and reaches the set point / good range
within [dSt] > Outputs remain active 2 The volumetric flow increases slowly and does not reach the set point / good
range within [dSt] > Outputs are reset

20

3 Volumetric flow falls below [LFC] within [dSt] > Outputs are reset at once; [dSt] is stopped

UK

3 Q below SP but above rP

5 Q reaches again LFC

range 8 Q reaches good range

5.10 Simulation

With this function, the process values volumetric flow, temperature and meter reading of the totaliser are simulated and their signal chain is checked

When the parameters crUL, UL, OL und crOL are set, process values that lead to an error message or warning can be simulated ( )

When the simulation is started, the values of the totalisers 1-3 are frozen and the

simulated totaliser is set to 0 The simulated volumetric flow value then has an

effect on the simulated totaliser When the simulation is ended, the initial totaliser

values are restored

UK

The simulation has no effect on the current process values The outputs

operate as previously set

During the simulation the original totaliser value remains saved without any changes even if there is a real volumetric flow

During the simulation no error message of the current application is available They are suppressed by the simulation

23

5.11 Colour of the characters in the display Via the parameters [coLF], [coLT] and [coLV] the colour of the characters in the display can be set: · Permanent definition of the display colour:
– bk/wh (black/white) – yellow – green – red · Colour change from red to green or vice versa (Fig 9): – r-cF (red display colour between the limits cFLcFH) – G-cF (green display colour between the limits cFLcFH)

cFL.T cFL.F MAW

cFH.T MEW cFH.F

Fig 9: Colour setting window function

cFLT = lower limit for temperature cFLF = lower limit for volumetric flow cFHT = upper limit for temperature cFHF = upper limit for volumetric flow

Select [Lox] or [Hix] to display the highest or lowest process value measured:
– [LoF] = min value of the volume flow measured in the process – [HiF] = max value of the volume flow measured in the process – [LoT] = min value of the temperature measured in the process – [HiT] = max value of the temperature measured in the process

Menu MEM: [LoF] [HiF] [LoT] [HiT]

Delete memory:

Select [Lox] or [Hix]

UK

Keep [] and [] pressed.

[—-] is displayed

Briefly press []

It makes sense to delete the memories as soon as the unit operates under normal operating conditions for the first time

11.6.2 Simulation
Select [SFLW] and set the volume flow value to be simulated Select [STMP] and set the temperature value to be simulated Select [STim] and set the time of the simulation in minutes Select [SOn] and set the function:
– On = The simulation starts The values are simulated for the time set under [STim] Abort by pressing any button
– OFF = The simulation is not active

Menu SIM: [SFLW] [STMP] [STim] [SOn]

12 Operation
The process values to be displayed permanently can be preset ( 11.5.2 Standard display) A standard unit of measurement can be defined for the volumetric flow measurement and temperature measurement ( 11.5.3 and 1154)
As an option for the preset standard display, the display can be changed by pressing the button [] or [] 9.1 Process value display (RUN)

13 Troubleshooting
The unit has many self-diagnostic options It monitors itself automatically during operation Warnings and error states are displayed even if the display is switched off Error indications are also available via IO-Link The status signals are classified according to NAMUR recommendation NE107 If several diagnostic events occur simultaneously, only the diagnostic message of the event with the highest priority is displayed
If a process value fails, the other process values are still available
Additional diagnostic functions are available via IO-Link IODD interface description at wwwifmcom
