MENU 1 – TOTAL
Total and flowrate are configured independently. Both have their own K-factor and measurement unit.
Example : Calculating the K-factor.
To manually calculate the K-factor to enter for total or flowrate, follow this example: Assume that the flowmeter generates 65.231 pulses per US gallon and the required measurement unit is cubic foot / ft3. A cubic foot consists of 7.48052 gallon which implies 487.9618 pulses per cubic feet. So, the K-Factor to enter is 487.9618.

Total and the scaled pulse output.

The following can be selected:

L– m3 – kg – LB – GAL – USGAL – bbl – (no unit).

1.2| DECIMALS| The decimal point determines for Total and Accumulated Total the number of digits following the decimal point.

The following can be selected: 0 – 0.1 – 0.02 – 0.003

1.3| K-FACTOR| With the Total K-Factor, the flowmeter pulse signals are converted to a total unit. The Total K-Factor is based on the number of pulses generated by the flowmeter per selected measurement unit

(SETUP 1.1). Use SETUP 1.4 to set the decimal point.

The more accurate the Total K-Factor, the more accurate the functioning of the system will be.

1.4| K-FACTOR DECIMALS| This decimal point determines for K-Factor (SETUP 1.3) the number of digits following the decimal point.

The following can be selected:

0 – 0.1 – 0.02 – 0.003 – 0.003 – 0.0004 – 0.00005 – 0.000006

MENU 2 – FLOWRATE
Changes to SETUP 2.1 Unit, SETUP 2.2 Time unit and SETUP 2.3 Decimals have an effect on the analog output settings of SETUP 4.2 Rate Min and SETUP 4.3 Rate Max. Therefore it is best practice to first determine the required settings for the flowrate!

following can be selected:

mL – L – m3 – g – kg – ton – GAL – bbl – lb – cf – none

2.2| TIME| The flowrate can be calculated per /sec – /min – /hour – /day.
2.3| DECIMALS| This setting determines for flowrate the number of decimals. The following can be selected:

0 – 0.1 – 0.02 – 0.003

2.4| K-FACTOR| With the Flowrate K-factor, the flowmeter pulse signals are converted to a flowrate unit. The Flowrate K-factor is based on the number of pulses generated by the flowmeter per selected measurement unit (SETUP 2.1).

The more accurate the K-factor, the more accurate the functioning of the system will be. Use SETUP 2.5 to set the decimal point.

The more accurate the Total K-Factor, the more accurate the functioning of the system will be.

2.5| K-FACTOR DECIMALS| This decimal point determines for K-Factor (SETUP 2.4) the number of digits following the decimal point.

The following can be selected:

0 – 0.1 – 0.02 – 0.003 – 0.003 – 0.0004 – 0.00005 – 0.000006

NAMUR| NAMUR input| 820 Ω pull-down| max. 4 kHz.| External power required
COIL| Coil input| –| min. 30 mVpp| –

MENU 4 – A-OUT (ANALOG OUTPUT)
An analog 4-20mA signal is generated according to the flowrate with a 10 bits resolution. The settings for Flowrate (SETUP-menu 2) influence the analog output directly and should be configured first. The relationship between rate and analog output is set with the following functions

power consumption to safe battery life. When the output is disabled, the current will be less than 3.4mA and the unit can still be supplied from this signal (provided a power supply is connected).

The following can be selected: enable – disable

While powering-up the loop, the initial current is approx. 3.3mA. When the output is enabled, it can take a few seconds to settle.
4.2| RATE-MIN (4mA)| Enter here the flowrate at which the output should generate the minimum signal (4mA) – in most applications at flowrate “0”.

The number of decimals displayed depend upon SETUP 2.3.

The time and measuring units (L/min for example) are dependent upon SETUP 2.1 and SETUP 2.2 and are displayed during editing.

If desired, you can program the analog output ‘up-side-down’. The

4mA represents the maximum flow rate. For example do enter 800 L/min.

4.3| RATE-MAX (20mA)| Enter here the flowrate-at which the output should generate the maximum signal (20mA) – in most applications at maximum flow. The number of decimals displayed depend upon SETUP 2.3.

The time and measuring units (L/min for example) are dependent upon SETUP 2.1 and SETUP 2.2 and are displayed during editing.

If desired, you can program the analog output ‘up-side-down’. The 20 mA represents the minimum flow rate.

For example do enter 0 L/min.

4.4| TUNE MIN (4mA)| The initial minimum analog output value is 4mA. However, this value might differ slightly due to ambient influences such as temperature for example. The 4mA value can be tuned precisely with this setting.
---|---|---
Before tuning the signal, be sure that the analog signal is not being used for any application!
After pressing SELECT+CLEAR, the current will be about 4mA. The current can be increased / decreased with the arrow-keys and is directly active. Press SELECT+CLEAR to store the new value.
4.5| TUNE MAX (20mA)| The initial maximum analog output value is 20mA. However, this value might differ slightly due to ambient influences such as temperature for example. The 20mA value can be tuned precisely with this setting.
Before tuning the signal, be sure that the analog signal is not being used for any application!
After pressing SELECT+CLEAR, the current will be about 20mA. The current can be increased / decreased with the arrow-keys and is directly active. Press SELECT+CLEAR to store the new value.

MENU 5 – D-OUT (DIGITAL OR PULSE OUTPUT)
The digital (transistor) output has a maximum frequency of 100Hz

pulse output length.

·         Off: the output is switched-off.

·         Long : represents a pulse length of 100ms (max. 5Hz.)

·         Inter : represents a pulse length of 15ms (max. 33Hz)

·         Short: represents a pulse length of 5ms (max. 100Hz.)

5.2| DECIMALS| The decimal point determines for AMOUNT (SETUP 5.3) the number of digits following the decimal point. The following can be selected:

0 – 0.1 – 0.02 – 0.003

If the frequency should go out of range – when the flowrate increases for example – an internal buffer will be used to “store the missed pulses”: As soon as the flowrate slows down, the buffer will be “emptied”.

It might be that pulses will be missed due to a buffer-overflow, so it is advised to program this setting within its range!

5.3| AMOUNT| One pulse is generated every X-quantity measured. If for example you want 100 pulses per gallon: do enter 0.01 GAL (this means one pulse every 0.01 GAL, so 100 pulses per gallon).

MENU 6 – OTHER

• Two basic types of flowmeter signals can be connected to the unit: pulse or sine-wave (coil). The screen of the signal wire must be connected to the common ground terminal (unless earthed at the sensor itself).
• The sensor output of the flowmeter should match with the selected flowmeter input signal at
• SETUP 3.1. See paragraph 3.3.4 for more information. Sine-wave signal (Coil)
• The B-SMART is suitable for use with flowmeters which have a coil output signal. The minimum sensitivity level is 30mVpp

Pulse-signal NPN
The B-SMART is suitable for use with flowmeters which have a NPN output signal. For reliable pulse detection, the signal should be above 1.4V or below 1.0V under all circumstances. It is advised to use a sensor which is normally open and is closed for a small time (less power consumption).

Pulse-signal PNP
The B-SMART is suitable for use with flowmeters which have a PNP output signal. 3.0V is offered on terminal 3 which has to be switched by the sensor to terminal 2 (SIGNAL). For reliable pulse detection, the signal should be above 1.4V or below 1.0V under all circumstances. It is advised to use a sensor which is normally open and is closed for a small time (less power consumption). In case of an active signal, the maximum voltage is 30V DC. Terminal 4 can offer a sensor supply voltage of 8.2V DC with an external power supply.

Reed-switch
The B-SMART is suitable for use with flowmeters which have a reed-switch. Make sure the contact resistance of the reed switch is less than 10k Ohm.

NAMUR-signal
The B-SMART is suitable for flowmeters with a NAMUR signal. The B-SMART is able to power the NAMUR sensor via the 8.2V sensor supply (terminal 4).

TERMINAL 5-6: ANALOG OUTPUT

• The functionality of the analog output is programmed through the A-OUT menu (SETUP-menu 4). See paragraph 3.3.5 for more details.
• The analog output generates a 4-20mA output signal proportional to the measured flowrate and can power the B-SMART from the loop. When the output is disabled, a constant current of 3.3mA is generated.
• The analog output is passive and requires an external 12-30V DC supply to function with a maximum driving capacity of 600 ohm @ 24V DC (24-12V/20mA). The output is not isolated from the internal electronics. If the unit is only powered by the loop the backlight will not be activated

TERMINAL 7-8: DIGITAL OUTPUT

• The functionality of the digital output is programmed through the D-OUT menu (SETUP-menu 5). See paragraph 3.3.6 for more details.
• One passive transistor output is available with a maximum pulse frequency of 100Hz. Max. driving capacity 300mA@30V DC.

TERMINAL 9-10: POWER SUPPLY
Connect an external power supply of 10-30VDC to these terminals. The maximum current is 25mA. When power is applied to these terminals, the sensor voltage on terminal 4 becomes available, discharge of the internal battery is disabled and the backlight can be used.

SERVICE PORT

The service port is available to configure the B-SMART via an external device, e.g. a laptop. The port does not use the standard type connectors, but the connections are made with a special service port communications cable, which is available through your supplier or our website, as shown below.
The service port is not intended to be connected with a permanent connection

MAINTENANCE

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. Take careful notice of the “Safety rules, instructions and precautionary measures” in the front of this manual.
• The B-SMART 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. 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 B-SMART 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 user’s responsibility to take all precautions to dehumidify the internal atmosphere of the B-SMART 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 lifetime
The life-time of the battery is influenced by several issues:

• Pulse output.
• Analog output signal: be sure that an external power supply is connected or that the function is disabled if not in use, as this has a major influence on the battery lifetime.
• Low temperatures; the available power will be less due to battery chemistry.
• NPN and PNP inputs consume more energy than coil inputs.
• High input frequency.

It is strongly advised to use only necessary functions.

Check periodically

• The condition of the enclosure, 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. Replacement battery: see technical specifications.
• Clean the enclosure with a lint-free cloth, soaked with a mild soap solution or fresh water.

PROBLEM SOLVING

In this appendix, several problems are included that can occur when the B-SMART is going to be installed or while it is in operation.

Flowmeter does not generate pulses
Check:

• Signal selection SETUP 3.1.
• Pulse amplitude (paragraph 3.3.4).
• Flowmeter, wiring and connection of terminal connectors (paragraph 4.7.1).
• Power supply of flowmeter (paragraph 4.5.2).

Flowmeter generates “too many pulses”
Check:

• Settings for Total (SETUP 1) and Flowrate (SETUP 2).
• Type of signal selected with actual signal generated (paragraph 3.3.4),
• Sensitivity of coil input.
• Proper grounding of the B-SMART, avoid ground loops.
• Use screened wire for flowmeter signals and connect screen to the ground input terminal of the flowmeter input.

Flowrate displays “0 / zero” while there is flow (total is counting)
Check:

• SETUP 2.2 / 2.4: are the K-factor and time unit correct?

Analog output does not function properly
Check:

• SETUP 4.1: is the function enabled?
• SETUP 4.2 / 4.3: are the flow-levels programmed correctly?
• SETUP 4.4 / 4.5: are the 4mA and 20mA tuned correctly?
• Connection of the external power-supply according to the specification.

Pulse output does not function
Check:

• SETUP 5.1 – mode: is the correct function selected?
• SETUP 5.1 – mode: is the external device able to recognize the selected pulse width and frequency?
• SETUP 5.2/5.3 – amount per “x” quantity: is the value programmed reasonable?

The password is unknown
If the PIN cannot be retrieved, 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 key several times to display the error code. The codes are:

• 0001 = display error
• 0002 = data-storage error
• 0004 = initialization error

When multiple alarms occur, the error code shown is the sum of the error codes as given above. E.g. 0005 is a combination of error code 0001 and 0004. If the alarm occurs more often or stays active for a long time, please contact your supplier.
