This is the main display information of the F012-P. After selecting any other information, it will
always return to this main display automatically.
Total is displayed on the upper-line of the display and flowrate on the bottom line.
It is possible to display flowrate only with the large 17mm digits; in this instance press the
SELECT-key to read the total.
When "-------" is shown, then the flowrate value is too high to be displayed. The arrows 
indicate the increase/decrease of the flowrate trend.
Clear total
The value for total can be re-initialized. To do so, press CLEAR twice. After pressing CLEAR
once, the flashing text "PUSH CLEAR" is displayed. To avoid re-initialization at this stage,
press another key than CLEAR or wait for 20 seconds.
Re-initialization of total DOES NOT influence the accumulated total.
Display accumulated total
When the SELECT-key is pressed, total and accumulated total are displayed. The
accumulated total cannot be re-initialized. The value will count up to 99,999,999,999. The unit
and number of decimals are displayed according to the configuration settings for total.

3.2.3. EXPLANATION OF SETUP-FUNCTIONS
1 - TOTAL
MEASUREMENT UNIT
11 SETUP - 11 determines the measurement unit for total and accumulated
total. The following units can be selected:
L - m3 - kg - lb. - GAL - USGAL - bbl - _ (no unit).
Alteration of the measurement unit will have consequences for operator
and SETUP-level values.
Please note that the K-factor has to be adapted as well; the calculation is
not done automatically.
DECIMALS
12 The decimal point determines for total and accumulated total the number
of digits following the decimal point. The following can be selected:
0000000 - 111111.1 - 22222.22 - 3333.333
K-FACTOR
13 With the K-factor, the flowmeter pulse signals are converted to a quantity.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 11), for example per
cubic meter. The more accurate the K-factor, the more accurate the
functioning of the system will be.
Example 1: Calculating the K-factor.
Let us assume that the flowmeter generates 2.4813 pulses per
liter and the selected unit is "cubic meters / m3". A cubic meter
consists of 1000 parts of one liter which implies 2,481.3 pulses
per m3. So, the K-factor is 2,481.3. Enter for SETUP - 13:
"2481300" and for SETUP - 14 - decimals K-factor "3".
Example 2: Calculating the K-factor.
Let us assume that the flowmeter generates 6.5231 pulses per
gallon and the selected measurement unit is gallons. So, the K-
Factor is 6.5231. Enter for SETUP - 13: "6523100" and for
SETUP - 14 decimals K-factor "6".
DECIMALS K-FACTOR
14 This setting determines the number of decimals for the K-factor entered.
(SETUP 13). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this setting influences the accuracy of the K-factor
indirectly. (i.e. the position of the decimal point and thus the value given)
This setting has NO influence on the displayed number of digits for total
(SETUP 12)!

HF012PEN_v0402_03 Atex_IECEx_CSA_FM
Page 13
2 - FLOWRATE
The settings for total and flowrate are entirely separate. In this way, different units of measurement
can be used for each e.g. cubic meters for total and liters for flowrate.
The display update time for flowrate is one second or more.
MEASUREMENT UNIT
21 SETUP - 21 determines the measurement unit for flowrate.
The following units can be selected:
mL - L - m3 - mg - g - kg - ton - GAL - bbl - lb - cf - REV -
no unit - scf - Nm3 - NL - P.
Alteration of the measurement unit will have consequences for operator
and SETUP-level values.
Please note that the K-factor has to be adapted as well; the calculation is
not done automatically.
TIME UNIT
22 The flowrate can be calculated per second (SEC), minute (MIN), hour
(HR) or day (DAY).
DECIMALS
23 This setting determines for flowrate the number of digits following the
decimal point. The following can be selected:
00000 - 1111.1 - 2222.22 - 3333.333
K-FACTOR
24 With the K-factor, the flowmeter pulse signals are converted to a flowrate.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 21), for example per
liter. The more accurate the K-factor, the more accurate the functioning of
the system will be. For examples read SETUP 13.
DECIMALS K-FACTOR
25 This setting determines the number of decimals for the K-factor
(SETUP 24). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this SETUP - influences the accuracy of the K-factor
indirectly.
This setting has NO influence on the displayed number of digits for
"flowrate" (SETUP 23)!
CALCULATION
26 The flowrate is calculated by measuring the time between a number of
pulses, for example 10 pulses. The more pulses the more accurate the
flowrate will be. The maximum value is 255 pulses.
Note: the lower the number of pulses, the higher the power consumption
of the unit will be (important for battery powered applications).
Note: for low frequency applications (below 10Hz): do not program more
than 10 pulses else the update time will be very slow.
Note: for high frequency application (above 1kHz) do program a value of
100 or more pulses.
CUT-OFF TIME
27 With this setting, you determine a minimum flow requirement thresh-hold,
if during this time less than XXX-pulses (SETUP 26) are generated, the
flowrate will be displayed as zero.
The cut-off time has to be entered in seconds - maximum time is 999
seconds (about 15 minutes).

HF012PEN_v0402_03 Atex_IECEx_CSA_FM
Page 14
3 - DISPLAY
FUNCTION
31 The large 17mm digits can be set to display total or flowrate.
When "total" is selected, both total and flowrate are displayed
simultaneously.
When "flowrate" is selected, only flowrate will be displayed with it’s
measuring unit while total will be displayed after pressing SELECT.
The functions below will only effect the optional LED-backlight.

The density of the backlight can be set in following range:
1-5
One is minimum and five is maximum brightness.
4 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F012-P has several smart power management functions to extend the battery life
time significantly. Two of these functions can be set:
LCD NEW
41 The calculation of the display-information influences the power
consumption significantly. When the application does not require a fast
display update, it is strongly advised to select a slow refresh rate.
Please understand that NO information will be lost; every pulse will be
counted and the output signal will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example battery life-time:
life-time with a coil pick-up, 1kHz. pulses and FAST update: about 2 years.
life-time with a coil pick-up, 1kHz. pulses and 1sec update: about 5 years.
Note: after a button has been pressed by the operator - the display
refresh rate will always switch to FAST for 30 seconds. When "OFF" is
selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
BATTERY-MODE
42 The unit has two modes: operational or shelf.
After "shelf" has been selected, the unit can be stored for several years; it
will not process the sensor signal; the display is switched off but all
settings and totals are stored. In this mode, power consumption is
extremely low.
To wake up the unit again, press the SELECT-key twice.

4.4. INSTALLING THE HARDWARE
4.4.1. INTRODUCTION
Electro static discharge does inflict irreparable damage to electronics! Before installing
or opening the unit, the installer has to discharge himself by touching a well-grounded
object.
This unit must be installed in accordance with the EMC guidelines (Electro Magnetic
Compatibility).
Do ground the aluminum casing properly as indicated, if the F012-P has been supplied
with the 115-230V AC power-supply type PM. The green / yellow wire between the back-
casing and removable terminal-block may never be removed.
Fig. 7: Grounding aluminum enclosure with option PM 115-230V AC.
FOR INSTALLATION, PAY EMPHATIC ATTENTION TO:
Separate cable glands with effective IP67 (NEMA4X) seals for all wires.
Unused cable entries: ensure that you fit IP67 (NEMA4X) plugs to maintain rating.
A reliable ground connection for both the sensor, and if applicable, for the metal casing. (above)
An effective screened cable for the input signal, and grounding of it’s screen to the “┴“ terminal
or at the sensor itself, whichever is appropriate to the application.

4.4.2. TERMINAL CONNECTORS WITH POWER SUPPLY - TYPE : PB / PD / PX
For Intrinsically Safe applications: read chapter 5.
The following terminal connectors are available:
Fig. 8: Overview of terminal connectors F012-P-(PB / PD / PX) and options.
SENSOR SUPPLY
Type PB / PD / PX - terminal 3: sensor supply 1.2V, 3.2V:
Terminal 3 provides a limited supply voltage of 3.2 V DC (coil signals 1.2V) for the signal output of
the flowmeter.
Note: This voltage MAY NOT be used to power the flowmeters electronics, converters etc, as it will
not provide adequate sustained power ! All energy used by the flowmeters pick-up will directly
influence the battery life-time (type PB). It is strongly advised to use a "zero power" pickup such as a
coil or reed-switch when operating without external power. It is possible to use some low power NPN
or PNP output signals, but the battery life time will be significantly reduced (consult your distributor).
Type PD - terminal 6: sensor supply 8.2V:
With this option, a basic but real sensor supply of max. [email protected] is available to power e.g. a
Namur sensor.
