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.
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
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 KFactor is 6.5231. Enter for SETUP - 13: "6523100" and for
SETUP - 14 decimals K-factor "6".
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)!

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.

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.
The flowrate can be calculated per second (SEC), minute (MIN), hour
(HR) or day (DAY).
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
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.
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)!
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.
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).

BATTERY-MODE
42
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 1 sec 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.
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.

For Intrinsically Safe applications: read chapter 5.
The following terminal connectors are available:
PULSE INPUT
TYPE: P
Fig. 8: Overview of terminal connectors H5012-P-(PB / PD / PX) and options.
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. 5mA@8.2V is available to power e.g. a
Namur sensor.
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or coil. The
screen of the signal wire must be connected to the common ground terminal
The input signal type has to be selected with the correct SETUP-function (read par. 3.2.3.)
Coil-signal:
The H5012-P is suitable for use with flowmeters which have a coil output signal.
Two sensitivity levels can be selected with the SETUP-function:
COIL LO: sensitivity from about 90mVp-p.
COIL HI: sensitivity from about 20mVp-p.
Type ZF (option): offers for setting COIL HI : sensitivity from about 10mVp-p.
Type ZG (option): offers for setting COIL HI : sensitivity from about 5mVp-p.

6. MAINTENANCE
6.1. GENERAL DIRECTIONS
Mounting, electrical installation, start-up and maintenance of the instrument may only
be carried out by trained personnel authorized by the operator of the facility. Personnel
must read and understand this Operating Manual before carrying out its instructions.
The H5012-P may only be operated by personnel who are authorized and trained by the
operator of the facility. All instructions in this manual are to be observed.
Ensure that the measuring system is correctly wired up according to the wiring
diagrams. Protection against accidental contact is no longer assured when the housing
cover is removed or the panel cabinet has been opened (danger from electrical shock).
The housing may only be opened by trained personnel.
Take careful notice of the " Safety rules, instructions and precautionary measures " in
the front of this manual.
The H5012-P does not require special maintenance unless it is used in low-temperature applications
or surroundings with high humidity (above 90% annual mean). It is the users responsibility to take all
precautions to dehumidify the internal atmosphere of the H5012-P in such a way that no
condensation will occur, for example by placing dry silica-gel sachet in the casing just before closing
it. Furthermore, it is required to replace or dry the silica gel periodically as advised by the silica gel
supplier.
Battery life-time:
It is influenced by several issues :
Type of sensor: read chapter 3.2.3. NPN and PNP inputs consume more energy than coil inputs.
Input frequency: the higher the frequency, the shorter the battery life-time.
Flowrate calculation: the lower number of pulses (SETUP 26) the shorter the battery life-time.
Display update: fast display update uses significantly more power.
Low temperatures; the available power will be less due to battery chemistry.
Note: It is strongly advised to use only necessary functions.
Check periodically:
The condition of the casing, cable glands and front panel.
The input/output wiring for reliability and aging symptoms.
The process accuracy. As a result of wear and tear, re-calibration of the flowmeter might be
necessary. Do not forget to re-enter any subsequent K-factor alterations.
The indication for low-battery.
Clean the casing with soapy-water. Do not use any aggressive solvents as these might damage
the coating.
6.2. REPAIR
This product cannot be repaired by the user and must be replaced with an equivalent certified
product. Repairs should only be carried out by the manufacturer or his authorized agent.

APPENDIX B: PROBLEM SOLVING
In this appendix, several problems are included that can occur when the H5012-P is going to be
installed or while it is in operation.
Flowmeter does not generate pulses:
Check:
Signal selection SETUP - 51,
Pulse amplitude (par. 4.4.2. / 4.4.3.),
Flowmeter, wiring and connection of terminal connectors (par. 4.4.2. / 4.4.3.),
Power supply of flowmeter (par. 4.4.2. / 4.4.3.).
Flowmeter generates "too many pulses":
Check:
Settings for total and Flowrate: SETUP 11-14 and 21-27,
Type of signal selected with actual signal generated - SETUP - 51,
Sensitivity of coil input - SETUP - 51 and par. 4.4.2 / 4.4.3.
Proper grounding of the H5012-P - par. 4.4.1.
Use screened wire for flowmeter signals and connect screen to the “┴ “ terminal.
Flowrate displays "0 / zero" while there is flow (total is counting):
Check:
SETUP 22 / 25: are the K-factor and time unit correct?
SETUP 26 / 27: The unit has to count the number of pulses according to SETUP 26 within the
time according to SETUP 27. Make sure that 27 is set to 10.0 seconds for example : the result is
that the unit has at least 10 seconds time to measure the number of pulses according to SETUP
26.
The pass code is unknown:
If the pass code is not 1234, there is only one possibility left: call your supplier.
ALARM
When the alarm flag starts to blink an internal alarm condition has occurred. Press the "select
button" several times to display the 5-digit error code. The codes are:
0001: irrecoverable display-data error: data on the display might be corrupted.
0002: irrecoverable data-storage error: the programming cycle might have gone wrong: check
programmed values.
0003: error 1 and error 2 occurred simultaneously
The alarm condition will almost certainly be handled internally and if all mentioned values still appear
correct, no intervention by the operator is needed. If the alarm occurs more often or stays active for
a longer time, please contact your supplier.
