Introduction
Device description
Gas volume conversion device PTZ-BOX 5.0 is a device used for measurements of gas volume at base
conditions and energy. It is designed to be used at gas measuring stations and pressure reduction-
measuring stations. It can cooperate with rotor and turbine gas meters.
PTZ-BOX 5.0 according to standard EN 12405-1:2018 is a gas volume conversion device
type 1.
Basic configuration of PTZ-BOX 5.0 offers:
-analogue input (pressure P1 –metrological channel),
-analogue input (temperature T –metrological channel),
-5 configurable potential-free contact inputs (DI1 to DI5):
oMeasuring inputs LF1, LF2 (inputs DI3, DI4) –frequency up to 60 Hz with the
possibility of cooperation with Wiegand transmitters, detection of flow direction
(when using two LF inputs with phase shifted pulses)
oTS input –default tamper switch, normally shorted (input DI5),
oUp to 5 digital inputs (inputs DI1, DI2, DI3, DI4, DI5)1,
-2 configurable NAMUR inputs (inputs DI6, DI7):

HF inputs with phase shifted pulses)
oHF2 (DI7) input can work with NAMUR encoder,
oUp to 2 NAMUR digital inputs1,
-SCR input for SCR encoder (optionally, interchangeable with DI8 - potential-free digital input,
depends on hardware configuration),
-4 outputs of „open collector” type:
oDO1: configurable –binary or frequency (1÷1000 Hz),
oDO2..DO4: binary,
-communications:
oCOM1 –standard RS-485, active with external power supply,
oCOM2 –standard RS-485, galvanic insulated, typically active with external power
supply, active on battery power when the casing is opened,

Function principle
1.2.1 General characteristics
•The measurement is based on counting of the volume at measurement conditions, based on
amount of pulses from reed contact LF or high frequency HF sensor mounted in the head of
the gas meter or from direct readout of gas meter counter with use of its built-in encoder.
•With built-in sensors device measures pressure and temperature of gas.
•Device converts the counted gas volume at measurement conditions into volume at base
conditions (EN 12405-1:2018) and using pre-set gas parameters it computes value of energy
(EN 12405-2:2012).
•Beside measurements and computation of current parameters, device also archives chosen
parameters and information about registered alarm states –available for later readout.
•The incorporated display and keyboard enable to monitor current measurement data, peak
values and alarms as well as to adjust the basic operating parameters, such as time and date,
measurement input limits, transmission parameters, and the like. Any modification of
parameters both via transmission and with use of the keyboard requires user authorization.
•PTZ-BOX 5.0 is a device powered by internal battery, but it also can be powered by external
power supply. In standard version, at typical operating conditions (1-2 readouts per month) 1
piece of battery allows up to five years of lifetime.
•Device has functions, which allow to use it in control and telemetry systems. During use of
these features it is necessary to connect applicable type of AC power adapter, which
provides separation of intrinsically safe circuits and allows to power by external supply of
device. AC power adapter is an optional accessory.
1.2.2 Measurement –calculation cycles
PTZ-BOX 5.0 device operates by default in measurement-calculation cycle:
•Every 30 seconds –when running in BATT mode (powered from internal battery),
•Every 1 second –when running in FULL mode (powered from external power source),
•Every 1 second –when display is turned on (in all power modes),
•Frequency of mentioned cycles in BATT mode could be set in range of 6..30s (up to 60s when
device is non-MID version);
•In every cycle, at first step device performs read of information about values of all measuring
inputs and calculates increments from chosen counting input. Basing on this input data PTZ-
BOX 5.0 calculates increment of volume at measurement conditions dVm, adds it up to
counter Vm and computes value of flow at measurement conditions Qm. At the same time,
device checks, whether new alarms have occurred or earlier alarm situations have been
closed.
•In next step, basing on the current values of pressure p1, temperature tand programmed gas
parameters, unit calculates conversion factor Cand then increment of volume at base
conditions dVb and flow Qb. Simultaneously there are calculated values of: dE, dM, QE, QM.
1.2.3 Emergency state
During typical usage of the device, depending on the appearance of alarm situation, it can operate
either in normal state or in emergency state. All parameters listed before are active in both states of
device operation (calculation of temporary values of flows and counters increments).
If the unit operates in normal state, all calculated increments are added up to main counters („n” -
new value of parameter, „p” - value from previous calculation cycle):

PTZ-BOX 5.0 User manual, document edition: 13

Vmn= Vmp+ dVm
Vbn = Vbp+ dVb
En = Ep+ dE
Mn = Mp+ dM
During normal state, emergency counters are stopped.
If the unit operates in emergency state, all calculated increments are added up to emergency
counters:
Vmen= Vmep+ dVm
Vben= Vbep+ dVb
Een= Eep+ dE
Men= Mep+ dM
During emergency state, the main counters Vb, E and M are stopped. Vm counter is always
active.
Emergency state of PTZ-BOX 5.0 is active as long as an alarm from a system group is active.
1.2.4 Calculation of conversion factor C
The main objective of the gas volume conversion device is to calculate conversion factor to base
conditions C, which is later used to convert values obtained at the measurement conditions into
values at the base conditions.
To calculate coefficient C, following values are used:
-pressure p1 and temperature t, coming from modules at the left side of Figure 1.
-compressibility factors: at measurement conditions Zand at base conditions Zb –computed
basing on measured values of gas pressure, temperature and current gas composition.
If values of pressure or temperature will exceed the ranges determined for currently used algorithm,
an alarm of algorithm error will be generated, and further results will be saved into emergency
counters. Calculation of compressibility factors is possible even if values of p1 and twill be out of
ranges (however, keep in mind, that uncertainty of performed calculations in this conditions will be
increased). If chosen calculation algorithm is unable to perform further computation, then last
calculated values of Zand Zb are used.
-base pressure pb and base temperature Tb.
Both of those values are describing the base conditions, on which values obtained at measurement
conditions are going to be converted. Additionally, combustion temperature for computation of the
superior calorific value Hs (T1).
Basing on parameters presented before, a Conversion factor to base conditions Cis calculated:

WARNING! In algorithms SGERG-88, AGA8-G1, AGA8-G2, AGA NX-19-mod and K1-const device
requires to program values of superior calorific value Hs and relative density dspecified for used
base conditions Tb and pb and combustion process T1 and P1 (always P1=pb). If given values of Hs
and d are known for different base conditions than ones used in the device, they must be
recalculated for those base conditions before programming. Methods for recalculations of Hs and d
between different base conditions are described in standard EN ISO 6976:2005, annex J and in
standard EN ISO 12213-3:2010, annex D. When programming full gas composition, no further
recalculations are necessary.
1.2.5 Increment of volume at measurement conditions
Device’s configuration allows to choose method of obtaining volume at measurement conditions
basing on data from pulse inputs LF and HF, additionally from digital input of encoder.
In configurations with LF as main counting input (configurations: LF1, LF1/LF2, LF1/HF1, LF1/SCR,
LF1/EN) increment of volume at measurement conditions dVm is calculated with formula:

 (2a)
where:
dLF –increment of pulses on LF input during measurement-calculation cycle,

PTZ-BOX 5.0 User manual, document edition: 13

LF factor –LF input pulse rate.
In configurations with HF as main counting input (configurations: HF1, HF1/LF1, HF1/HF2, HF1/SCR,
HF1/EN) increment of volume at measurement conditions dVm is calculated with formula:
  
 (1b)
where:
dHF –increment of pulses on HF input during measurement-calculation cycle,
HF factor –HF input pulse rate.
In configurations with EN and SCR as main counting input (configurations: EN, EN/LF1, EN/HF1, SCR,

   (2c)
where:
dVo –increment of auxiliary counter Vo, derived from direct reading of encoder.
Increments dVm are summed in Vm counter during normal and emergency mode. During emergency
mode, additional auxiliary emergency counter of volume at measurement conditions Vme is driven.
1.2.6 Averaged conversion factor
A value of arithmetic average of conversion factor Cis calculated in the device. By default,
averaged value is equal to momentary value from current measurement-calculation cycle. Averaging
of conversion factor covers the period in which flow of gas has been observed (flow rate Qm>0), but
in following measurement-calculation cycles increment of volume at measurement conditions
counter value dVm was not detected. When finally increment of that counter is detected –period of
averaging value of Cends.
E.g. measurement-calculations cycle period is 30 seconds and increment of volume at measurement
conditions dVm occurs e.g. every 180 seconds (it could be correct period of incoming low frequency
pulses LF or readouts of encoder’s counter state). Counting from 0 second – every 30 seconds device
calculates momentary value of conversion factor Cand its averaged value. In 180th second, increment
of dVm counter will be detected and calculation of increased volume at base conditions will be
carried with use of averaged C. This allows to take into account of following calculations possible
dynamic changes of pressure or temperature or gas composition during period of volume increment.

PTZ-BOX 5.0 is the intrinsically safe equipment. The housing of the device should be
sealed –replacement of the battery can only be carried out by an authorized person, i.e.
a factory or authorized service representative or other persons authorized by the
manufacturer.
It is permissible to replace the batteries in the explosion hazard zone.
For power supply of PTZ-BOX 5.0 only batteries of the types: LS33600 (Saft), SL2780
(Tadiran) or ER34615 (EVE), may be used. When using batteries type EVE ER34615 range
of ambient temperature is limited to (-25 ÷+50) °C.
It is prohibited to combine different types of batteries in one device.
Opening of device’s housing is forbidden under conditions that allow ingress of water
(for example rain, snow) or dirt inside the unit.
Always replace the battery with a new, full charge batteries.
Battery replacement causes break in measurements of pressure and temperature, but allows to keep
counting of LF pulses (not converted to volume until new battery is connected) and working of real
time clock. Settings and registered data are not affected.
Figure 4. Insertion of batteries
Inserting of old, partly discharged batteries will cause incorrect readouts of charge level
and may lead to unexpected device operation (such as restarting, errors in counting, errors
in archives and in current values).
Discharged batteries are in the hazardous waste category, therefore they must not be
disposed together with common waste.

Declared by manufacturer IP class of housing protection will be maintained when the
gasket is properly seated and the housing cover is tightened.
2.3.3 Backup battery
The battery maintains backup of device’s crucial functions in case of discharge or replacement of
main battery. It allows to keep counting of LF pulses and working of real time clock while battery
replacement procedure is in place. The backup battery may be replaced by authorized service after
metrological seal is broken.
Only type 1/2AA LS14250 (Saft) or ER14250H (Fanso) backup batteries may be used.
2.3.4 External power supply
External power supply is required when using:
-HF inputs.
External power supply is recommended for cases of high power usage:
-frequent communications,
-frequent screen usage,
-NAMUR/SCR encoder.
Power supply is intrinsically safe type circuit, with intrinsic safety parameters given in paragraph 13.
External power supply of device should be connected to terminals 1, 2 –according to indications on
wiring diagram. Parameters of power supply are described in paragraph 13.
The cables used must meet requirements for type B cables in accordance with standard EN 60079-14
–in particular, wire insulation should withstand the test voltage 500 V AC and cannot be thinner than
0.1 mm (for insulation of polyethylene 0.2 mm).
Sealing of the unit
PTZ-BOX 5.0 as a device for billing, should be protected against unauthorized access. To do this, unit
housing is secured with seals like presented on figure below and access to the menu is protected by a
password system. Damage of any sealing marks causes loss of confirmation of device’s metrological
features and certifications. Avoid damaging of seals during installation and operation of the device.
Installation staff is obligated to verify condition of seals before mounting of device. If the seals are
damaged, the proper functioning of device must be checked by the manufacturer authorized service.
Unauthorized opening of the device, mounting inconsistent with this documentation or
any changes to construction of the device can lead to loss of intrinsically-safe features
and/or metrological characteristics and/or radio equipment characteristics. Damage of
any sealing marks causes loss of confirmation of metrological, intrinsically-safe, radio
equipment features of the device.
