Before You Start The G4S series meter is a high accuracy measuring instrument that must be handled with care. The meter should always be kept in vertical position, in service and during transportation. The device should be fitted only by competent engineers, qualified to the relevant national legal requirements and following all national and local regulations such as BS 6400 Product Description G4S series meter is a smart diaphragm gas meter, SMETS compliant, with an electronic...

The meter has an internal valve, electronically controlled, to allow the gas supply to be disconnected and reconnected as required. The gas supply cannot be reconnected without the presence of someone at the meter. When the command to open the valve is received by the meter, a button press is then required at the meter.

You will also find the unique Meter Serial Number (MSN) of the meter, in the form “G4F………..” below the display. There is also the Flonidan internal serial number in the form “S/N 115xxxxxxxx”, there is full traceability of the internal components of the meter from the either of these numbers.
Liquid Crystal Display Display is readable at angles ± 45° horizontally as well as vertically at temperatures within the operating range. Volume read out for the UK is set to the form “xxxxx.yyy” it is not configurable and will always display leading zeros, as per SECAS rules. Example: (note leading Zeros may be hidden) Symbols shown at the top of the display when either the volume or the balance screen is displayed:...

Billing and Tariffs Legally relevant data for billing is sent over the Home Area Network (HAN) to the communications hub once per day. However, consumption data is transmitted every half an hour. This can be relayed to the in-home display and the Head End System (HES) Tariffs The meter is able to count the gas consumption in 4 different registers (Tariff T1, T2, T3 and T4), depending on the time of use.
Block tariff counters, m Block tariff prices Mechanical Operation Diaphragm Valve Mechanism The diaphragm meter consists of an “engine” placed inside a metal case. The engine has 2 chambers, each separated by a flexible diaphragm. A valve system allows the gas within the unit to pass into one side of the diaphragm.

The system will generate an alarm if the wheel is rotating backwards or if the Gray code detected differs from the Gray code expected. The meter will detect backflow of up to 1/2 cyclic volume. Further backflow will activate an error Gray coded wheel fits in this slot Index PCB...
Gas Flow Measurement The rotating of the Gray code wheel is converted into volume measured. The volume measured is corrected by the error curve correction function as described in 4.4. The corrected cyclic volume is then corrected for temperature as described in chapter 4.5. and shows as V on the balance display.
Meter Security Index Cover The index cover is held in place using two secondary anti tamper seals. Removal of these seals will mean permanent damage to the seal or permanent damage to the cover. Tamper detection methods will be used to detect the removal of the cover and an alarm symbol may be displayed on the LCD.
Memory Configuration and Security data is kept in an internal flash in the microprocessor and is loaded at manufacture and never changed again. All other data is held in external memory (Flash or EEPROM) Supply Valve (Electro Valve) The electrically operated ball valve is located close to the output connection of the gas meter.
Note: the valve will not actually open unless there is someone present at the gas meter, reading and following the instructions. This is for Health and Safety reasons, to prevent the gas being re-connected when no one is at home or when an appliance is ”on” but not ignited, this is known as the safe opening process and is detailed later Supply re-connection from HES 7.1.5...
When the supply is asked to be re-connected (open the valve) the following happens 1. At the bottom line of the display the following messages will be shown alternatively (flashing) “turn off all appliances” & “Press button to connect” 2. After pressing the button, the valve will open a little and the meter will check that there is no gas flow/consumption 3.
COMMS module 3.yy.zz Example: 3.10.7 • yy = SMETS determinant: ▪ 10 = SMETS 2 • zz = firmware version number The firmware version can be viewed on the display from “DEVICE INFO”. Firmware Upgrade Firmware can be upgraded Over The Air (OTA) via the back office using the HES and HAN.
Communication Features and Functionality The index has 2 communication methods Optical head (IR-head), for service and diagnostics Wireless ZigBee connection to HAN (Home Area Network) Optical Note: this feature is not available in the field (see 2.4 above) Optical interface (IEC 62056-21) has optimal security using AES encryption with symmetric encryption keys.
The Alerts in SMETS 2 are defined by the GBCS Table 3 Mandatory and Non-mandatory ALERTS All mandatory alerts are supported by the Flonidan G4SZV-1 SMETS 2 meter. Most of the non- mandatory alerts are also supported a full list can be found in the Customer card.
Maintenance Battery life Calculation 15.1 The energy remaining in the battery is calculated continuously based on the actual behaviour of the index. The “days left” before “battery low” is displayed on the index and calculated from the average consumption over the period of the last week. Consumption is calculated from these activities: Base consumption (measured with flow) Radio/ZigBee activity...
