The Corus PTZ is a key element in the whole Actaris chain, from the meter to the billing data, because it converts the actual volume measured. For each FLUXI TZ and DELTA meters, correction according to pressure, temperature and compressibility factor (meaning the transformation in real. CORUS is an electronic volume converter dedicated to commercial and industrial applications. It converts the actual volume measured by the gas meter to.

It is designed to calculate gas volumes under base conditions, based on a volume at metering conditions, a temperature, a pressure, a compressibility.
Its atcaris input is a low frequency one that can be connected to any Ex compliant gas meter that provides such information. Corus PTZ belongs to a new generation of volume converters that are designed to achieve a high level of performance thanks to a powerful electronic equipment. Based on the use of flash memory, its architecture allows the download of a new firmware dorus through a laptop without board modification. Corus PTZ is approved according the new European standard EN and it can be used for commercial and fiscal gas transactions.
According to the European regulation, it bears the CE marking and complies prz the following directives: Vm Pb T Z where: A hinge on the left of the box makes any operation on the corhs very easy, providing a clear access to all major parts of the product terminals, switches, internal battery,… Corus PTZ is built with three electronic boards: RAM and flash memories, …? These plates are screwed and sealed. Any attempt to open the box lets permanent visible marks on the seal or on the enclosure.
This seal notably protects the access to: This label is inviolable: This label provides the following data: LF input pulse weight? CE marking and data required by the potentially explosive atmospheres regulation Title: Its four wires mounting provides a high accuracy by eliminating the actarid of the cable.

The temperature sensor has an IP67 protection degree according to EN and is delivered with a pt length of either 2. The temperature measurement period is programmable from 1 to 20 seconds. This data is protected by the metrological switch. Two 2 operating pressure range are available: It can withstand an overpressure of 1.
It is delivered with a cable length of either 2. All pressure sensors are delivered with their own characterization coefficients 12 that must be programmed into the converter so actariss the accuracy required by EN can be reached over the whole pressure and temperature range. The adtaris measurement period is programmable from 1 to 30 seconds.
At a programmable period from 1s to 30s if the display is off same period than P and T acquisition?
Proofreader of volume of gas SEVc-D (Corus) PTZ, TZ, Itron (Actaris).
Pb T Z The reference pressure Pb and the reference temperature Tb must be programmed xctaris the device. The input pulse weight can be chosen among the following values: Corus PTZ can be delivered with several different LF cables, in order to comply with all existing types of meter connections. All cables are available with length of 0. They can be either: This input shares the same terminals J3 and J4 and the same cable as the main LF input. The tamper input can be put into one of the following modes: Ptzz allows to check the good operating of the metering function and of the pulse emitter of the meter.
The tamper input can be set into one of the following modes: The time closed of the volume pulse outputs can be programmed its default is value of ms. Base volume outputs are automatically disabled as long as any metrological alarm is active.
The activation duration of the alarm outputs can be selected. The alarm outputs can remain active: If the functions is activated, every time they are updated, the instantaneous flows are compared respectively to: This port can be used for serial asynchronous start-stop half-duplex communications. It operates at baud, baud, baud, baud.
A disc made into a magnetic material is fixed under the cover and allows the mechanical fixing of the optical head.

The presence of an optical head is magnetically detected. This allows the optical port to be by default in a power-down mode and to wake up automatically when necessary. In case of failure, the magnetic detection can be overridden by turning on the user interface. The terminal J6 that correspond to the serial port is located in the customer area: It operates at baud, baud, baud, baud, baud, baud. The RS port is by default in a power-down mode.
When the connected device initiates a communication, it has to take in account a wake up time of a few milliseconds. All daily consumptions are stamped from the gas hour to the gas hour of the next day. All monthly consumptions are stamped from the gas day at the gas hour to the gas day of the next month at the gas hour. The fixed part includes the following data: The capacity of the interval log extends from all optional fields selected to no optional field selected. For each event, following data are available: Date and time of the event?

Nature of the event? Specific value for some event only? Status The event log has a capacity of events and cannot be reset. Corus PTZ manages three pressure alarms: When a pressure alarm occurs: Corus PTZ manages three temperature alarms: The user can program a number of pulses Np and a duration Dp.
When the alarm occurs: Then, when Corus PTZ detects actairs an input is not in its normal state, the corresponding alarm is generated. When such an alarm occurs: This alarm is not metrological and is dedicated to the control of the whole metering chain.
Corus PTZ manages two conversion factor alarms: The interval can be selected among: If the function is activated, an alarm of the above list is set if the corresponding flow-rate gets higher or lower than the threshold.
When changing the battery, the battery counter has to be re-programmed so as to remove the battery alarm. When the battery alarm occurs: Then, this alarm is set actafis long as the external supply is not present.
During the main cut, the internal backup battery will ensure the total functioning of Corus PTZ and the battery counter will be ptx with the same management described in cotus “battery alarm” chapter. When such a alarm occurs: Press OK to confirm Through communication? Select the type of alarm to be resetted: The five keys allows to move into the various menus as described below. There displayed sequence is based on five main menus: Items can be selected using the ‘OK’ key.
When the display is off, any press on a key puts the display on. After 2 minutes with no action on the keyboard, the display switches off. When the display actarjs on, the acquisition of pressure, pz and the calculation of compressibility and conversion factor is performed every second. The ‘OK’ displays the date and time, as well as the firmware version numbers. From this screen, a long cors on the ‘OK’ key launches a test of the display. A press on the OK key displays a chart for the selected value.
The data is then displayed. Six 6 different menus are available including following parameters: Input pulse weight, unconverted Index, Converted Index: Pbase, Tbase, Gas composition according formula: Mode battery, externalautonomy: All alarms will be reset.
Press OK to confirm. Battery Current value Mode: Following the installation procedure, Corus PTZ has to be carefully closed using the four screws placed on each corner.
All cable glands have moreover to be tightened enough. These two actions are mandatory to achieve a correct water tightness of the enclosure.
The generally accepted installation actagis are: It must be preferentially screwed to the “Pr” reference pressure tap of the meter:
